If you then try to move components in the Structure TreeView by Drag&Drop you can't drop it onto a TreeView node which is currently not visible because the TreeView doesn't scroll when you're pointing your mouse near the edges of the TreeView.

[QC Description] The tab key should indent a block of text when it is highlighted. This is the behaviour of most other IDEs and makes more sense than the current key combination.
Shift+tab should unindent a block of text when it is highlighted.
This suggestion costs nothing to implement, has no negatives, makes life easier for people changing from VB, is intuitive for new users, and makes it easier for everyone who has ever had to indent text.
There is no need to remove the current functionality of tab when no block is highlighted. And there is no need to remove the other keystrokes which indent blocks of text.

[QC Description] When finding in files only the source code is searched. There is no such function for searching in all forms / data models within a project / directory etc.

Your customer asks you to change all texts / labels / ... from Automobile to Vehicle. You know this word is present is source code, on many forms in captions, hints etc.
Do a "Find in files" on Automobile with the (Associated files checkbox enabled or something like that). When you select the Automobiles found on DFMs it popups the form, selects the correct component/control, popups the Object Inspector and selects the correct property.

This could be [QC Description] particularly tricky to identify as a problem, considering that this, only slightly different, query works as expected: When parsing an SQL statement that contains strings literals, the ParseSQL implementation does not properly SELECT SYSDATE FROM DUAL WHERE USER IN ( 'LPs are 12" in diameter', 'CDs are 5" in diameter', 'My interpret quote characters embedded within those literals. TV is 16:9 ratio' )
A double-quote char (") encountered within a string literal (enclosed by a pair of ') is interpreted as the end of the string literal.
In most cases this is a silent failure, but if you also have string literals in the SQL that contain colons, then under the right conditions that colon is treated as a parameter identifier and not part of a literal.
We found this because we had a query that built a "WHERE COLUMN IN (

[QC Description] When you select Open Project from either the menu item or the toolbar, the filter used is wrong. By default the filter used is the "Borland Developer Studio File" which incase you don't know, includes just about every file you could ever hope to use in the IDE.
This is wrong. The reason I have done "Open Project" is so that I can open a PROJECT file. A PROJECT file for Delphi 2005 and it should be either a bdsproj or bdsgroup (I like to live in the NOW not the past). Not all of the legacy project file types. Once I've updated my project to Delphi 2005, I should not have to continually see these files in a default filter. For one thing it's off putting seeing twice as many files lists as I expected.
Perhaps there needs to be a "Delphi 2005 Project File" filter that includes bdsproj and bdsgroup ONLY and it's the default filter for the Open Project action.
If people want to upgrade a project to D2005, then let them select the Delphi Project or Delphi Package filters (which should be combined into a Delphi Legacy Filter IMHO).

Create empty VCL application. 2. Paste this procedure TForm1.FormCreate(Sender: TObject); var I : integer; Basic bug in clear leads to huge execution time begin FListView := TListView.Create(Self); with FListView do begin Parent := self; Align := alLeft; ViewStyle := vsReport; Columns.Add.Width := 200; SortType := stNone; Items.BeginUpdate; for I := 1 to 10000 do AddItem [QC Description] (IntToStr(I), nil); Items.EndUpdate; end; end; 3.

Then First the behavior: if you have a simple list with 10000 items, clearing takes a lot of time (populating takes also you can try the same using the attached comctrls unit (be sure to build with it). time, but that's something else).
Clear is sending LVM_DELETEALLITEMS message, which triggers LVN_DELETEALLITEMS notification.
There are several basic problems with notifications:
- Item.Destroy sends LVM_DELETEITEM message even if it's coming from a notification. This means that LVN_DELETEALLITEMS triggers one LVN_DELETEITEM also, which is totally unnecessary (there is some logic to avoid double free) IF LVN_DELETEALLITEMS returns 1.
- LVN_DELETEALLITEMS does NOT set the return value to 1 (same in LVN_DELETEITEM)! Because of this each list item must be deleted (in destroy) sending an explicit call.
Correcting these problems leads to an instant response for the clear call.

[QC Description] Currently, the current file search feature of the IDE pops up a modal dialog box, which the user fills out, and which then requires a click.
Since modal dialogs are rapidly going out of style, please institute a search functionality similar to that found in the Firefox web browser.
Rather than pop up a modal dialog, the IDE should display at the bottom of the editor a small tool bar that allows the user to type the search phrase into an edit box. Incremental search is done as the user types. If the user types something that is not found in the file, then a small "not found" sound is played. The tool bar can have common search choices such as "Match Case", "Find Next", "Find Previous", etc.
I've grown quite used to the Firefox Search model, and really like it. I think it would make a great addition to the Delphi IDE.

Previously, I could just hover. See Steps.
The above may be a change in behavior because it thinks I might be moving the mouse into the hint to expand something?
From Chris: Yes, before expandable hints, the code would keep the hint visible as long as the mouse stayed in the bounding rectangle of the editor token. Now, it uses a union of the editor token rect and the hint rect itself. So in most cases it won't go away when simply moving the mouse horizontally to a different token on the same line (depending on how wide the hint itself is).
There may be a way to be smarter about this. If you file a QC report for this, I'll investigate it.

(Creates another problem, see QC 10661: Install all components [QC Description] from JVCL and DevExpress, and then try this. Notice that it will take about 2-3 seconds for it to switch) Tested in non embedded, classic undocked.
Default behaviour is broken, as the designer now always show the design form of the unit when using Ctrl+F12 to view a new unit.
Default behaviour before was showing the source code, and is the most logical thing to have here since you want to vew the unit, not the form. You have Shift+F12 (View form) for that.
Since viewing a form takes 2 seconds on a XP 3200 with 1G RAM (when JVCL and DevExpress is installed), a bi effect is that switching units will take a long time. See QC 10661 for more info on this (speeded up a bit in D2005 update 3). But still slow.

Tried also with a simple delphi vcl forms app and had the same problem. - the command line output lists an option of -C0 [That's a Zero], which dccil doesn't understand.
- the command line output also lists the .dpk as *last* item of the commandline, leading dccil to emit "project $A-" not found. the project has to be the FIRST item on the command line
- it doesn't bother to prefix the $A+ etc compiler options with a "-"

This means that the toolbar buttons used to control the debug target application (such as pause) are no longer clickable. Perhaps some kind of throttling, or some kind of buffering is necessary for OutputDebugString output.
This is really severe because it means that the target delphi app (or C++Builder app, or perhaps even a dotNet app) that outputs enough output via the win32 api OutputDebugString could make the whole IDE unstable.
If the target application keeps outputing lots of OutputDebugString output permanently, then the only way out of the situation is to kill the IDE and the target Application exe. This causes major data loss.
This does NOT happen in Delphi 7. It appears to happen in Delphi 2005 and 2006. It may be infrequent for most users, since most users don't have a lot of outputdebugstring messages, and are probably careful not to generate a huge amount of it. but if you ever slip up and put a debug message somewhere where it gets hit 100 times a second, you can kiss your IDE goodbye.

[QC Description] When using TThread in suspended state, and FreeOnTerminate, TThread.Resume miss threadsafe handling of the thread.
Today the code looks like this: procedure TThread.Resume; var SuspendCount: Integer; begin SuspendCount := ResumeThread(FHandle); CheckThreadError(SuspendCount >= 0); if SuspendCount = 1 then FSuspended := False; end;
The problem is, if there are many threads created and freed, the delay after ResumeThread(FHandle) could be big enough for the thread to finish and free itself before the routine arrives at FSuspended := False.
This will cause TThread.Resume to set a value on the freed object, and in worst case corrupt memory on newly allocated memory for some other structure.
This routine has to be made threadsafe, with interlocked states or using a critical section. One solution could be something like this: [See resolution comment]

2. When a project is loaded: Clicking the Components/Install Packages menu item brings up a dialog/window 'Project Options for ThisProject.exe' which is NOT resizable. However obviously this is not the same dialog as when clicking Project/Options so the question arises why this dialog is not resizable as the dialog/window under 1.
Not resizable dialogs which contain lists of variable length are a very bad design, because the user has to scroll a lot to find the desired list item and he has no overview to the whole list.
Dialogs which are not resizable containing lists of variable length are a reminiscence to the old times of DOS where such cumbersome user interfaces were a result of the restricted technology at that time.

[QC Description] Delphi 2006 has rudimentary support for UTF-8 text through the UTF8String type. This report requests the completion of the compiler and language support necessary to make this type fully functional and on par with the AnsiString and WideString types.
Currently the type maps to a long string, which is great since that means it inherits some great features (allocation/deallocation speed, reference counting, etc.). However, there are many areas in which support is currently lacking:
1) Implicit type conversion: UTF8String is currently treated in exactly the same way as an AnsiString when doing assignments to different types, so assigning a UTF8String to a WideString or Ansistring will cause data corruption if the UTF8String contains code points outside the ASCII range (code points U+0 to U+7F). 2) Object Inspector support: UTF8Strings cannot be edited in the Object Inspector. Again, the UTF8String is treated as an ordinary AnsiString, and thus code points outside the ASCII range are lost or corrupted. 3) Compiler support for UTF-8 string constants: The compiler does not support the assignment of Unicode text constants to UTF8String variables. All code points outside the ASCII range are lost or corrupted when assigning a Unicode text constant to a UTF8String variable. The compiler should implicitly convert the constant to UTF-8 during compilation. 4) Manual type conversion functions (Utf8ToUnicode and UnicodeToUTF8) only support the BMP (Basic Multilingual Plane, plane 0. i.e. the first 64K code points): The RTL and IDE's Unicode support is still limited to UCS-2, whereas Windows has moved on to UTF-16.
Full support of UTF-8 is a worthwhile companion to full support of UTF-16. UTF-8 is more storage space efficient than UTF-16 when working with predominantly European languages. Backed by the long string type the UTF8String type is also faster than the WideString type because it is not allocated on the (slow) Windows heap, and it is also reference counted.

I have to be very vigilant to avoid accidentally editing the wrong file, because the IDE's ctrl focuses on the tab for the wrong Unit1.pas - the one located in Folder2 and left-click mechanism cannot always be trusted.

Unused Threadcount in classes.pas ThreadCount: Integer; procedure AddThread; begin InterlockedIncrement(ThreadCount); end; procedure RemoveThread; begin InterlockedDecrement(ThreadCount); end; [QC Description] Classes.pas has a unit variable ThreadCount in the implementation that is added to and subtracted from. Only it is never used. And since it is in implementation it cannot be used outside this unit. So there is a useless blocking (interlockedexchange) call for every thread created and destroyed. It is likely old leftover code because in D5 classes.pas threadcount variable is really used, but D7 en D2006 classes.pas do not use it anymore. It cannot be for threadsafety as interlockedexchange only synchs the variable inc/dec, nothing else.

The cause of the problem is that the code in TGIFImage.Assign assumes that TGIFFrame.Create doesn't add the frame to the parent TGIFImage and that TGIFImage.Add does. This was true in the old version but not in the new.

[QC Description] This functionality is needed by applications that can potentially load and display large number of GIFs.
Since an animated GIF can contain a large number of frames, and each frames uses up to two bitmap handles and one palette handle, apllications that needs to display arbitrary number of animated GIFs must be able to limit the GDI resource usage.
Most of the required functionality already exist, it just need to be made accesible.

I believe an alternate UI for those areas of the settings, or allowing this dialog to resize would make this dialog more usable.
The first 4(*) items in the list would give me a significant benefit, because I believe developers use them more frequently.
Tools (Environment) Options (Ignoring Together) ------Significant Benefit (central portion could resize, less scrolling, etc.): - Library Win32 (path lists)* - Environment Variables (variable lists)* - Color (syntax preview)* - Language Exceptions (exception list)* - Native OS Exceptions (exception list) - Event Log (color listbox very cramped)
Minor Benefit: - Environment Options (paths) - Object Inspector (color listbox) - Explorer (explorer categories) - CodeGear Debuggers (paths)
Little/No Benefit: - Tool Palette - Colors - Type Library - VCL Designer - Editor Options - Source Options (could resize, but large enough now) - Display - Key mappings (could resize, but large enough now) - Code Insight - Debugger Options
I'm happy to accept a better/alternate UI instead of resizing, if CodeGear can come up with one that performs the same function in less space, but resizing is the bet option I've imagined so far.

Class constructors in Delphi/Win32 Currently, I have to make the class var "private" instead of "strict private", and initialize it in the unit initialization section. This works, but it's poor encapsulation: the code for my class is not all with the class, and I have to use [QC Description] a weak visibility specifier (private) instead of a properly encapsulated visibility (strict private). ------unit It would be nice if Delphi for Win32 supported the "class constructor" syntax that is already supported in Delphi Comparers; interface type IComparer = interface function Compare(A, B: string): Integer; end; for .NET. TDefaultComparer = class(TInterfacedObject, IComparer) strict private class var FInstance: IComparer; public class constructor Create; function Compare(A, B: string): Integer; class property Instance: IComparer read This would basically be another "initialization" section (and run at the same time as all other "initialization" FInstance; end; implementation uses SysUtils; { TDefaultComparer } function TDefaultComparer.Compare(A, sections), but it would be scoped to the class, and therefore better encapsulated (both with regards to member B: string): Integer; begin Result := AnsiCompareStr(A, B); end; class constructor TDefaultComparer.Create; visibility, and just from the viewpoint of having all of the code that relates to the class as part of the class). begin // run at the same time as all unit initialization, // but has access to strict private & strict protected members FInstance := TDefaultComparer.Create; end; end.

[QC Description] Please implement closures / lambda / anonymous functions. Because the topic is (I presume) widely known, I don't insist now in benefits or in syntax descriptions. Of course, this can be implemented in Delphi using a CG like Boehm. Related to this, explore also this possibility to have unmanaged program elements and managed ones - but this is another topic.
My small proposal is to use an attribute like 'closure' (syntax is subject to change, of course) which will create behind the scenes an object which will be passed, as needed. For ex.: function Func1(aStr: string; aInt: integer): string; closure;
Will create internally something similar with the following structure
TFunc1 = class(TBaseClosure) ... Public _Context: somepointer; //the pointer to the context in which the code is executed aStr: string; //the parameters with the appropriate type aInt: integer; Execute: string; // the result has the appropriate type //for a procedure is a method here with no result end;
{var} Func1: TFunc1;
In short, we can see a closure declaration like a much more concise way to declare classes.
If someone has in his code ShowMessage(Func1('Test', 1)); the compiler will check if Func1 points to nil, if yes, then create the object, load the parameters in the object's fields, (or pass a pointer there if we speak about variable parameters) and execute the code returning the result (if appropriate). In fact, it's a usual way to simulate the closures, but without the overhead which is required from the programmer's POV regarding the object's lifecycle management, class declaration, code flexibility aso. As we saw, the 'closures' are created automatically at first call; they can be freed manually by invoking Func1.Free, which also must set the Func1 pointer to 'nil' in order to allow their safe re-creation on a new, possible call. If they aren't freed, the compiler must free them at the program termination. Also, explore the possibility of freeing them earlier (when they got out of scope etc.) but, imho, because, usually, the overhead by not freeing them is very little (in normal conditions), by simply freeing them at the program termination is already a very good solution.

3.4. Jake Jacobson's blog doesn't load correctly - you see lots of CSS markup instead of text (could of course be his own fault, but then his blogs should not show). ----- #3.4 Update: Cannot reproduce. User has been removed. ------

QC #: Date Reported: Area: 51427 8/31/2007 RTL\Delphi\RTL Exceptions Description: Steps: [QC Short Description] Run this code: program Project1; uses Windows, SysUtils; begin try raise Exception.Create('xxx'); except Halt Calling Halt in 'except' or 'finally' forcibly displays the exception message, and causes process to return wrong (5); end; end. Expected results (what happened in Delphi 2.0 through 2006): 1. The process should return with exit code an exit code of 5. Actual results on Delphi 2007: 1. A message box is displayed: ------Application Error ------Exception Exception in module Project1.exe at 00055753. xxx. ------OK ------2. The process returns with an exit code of 1, not 5. (JJS: Seems related to 255308 but reproducible with D2007 December Update)
[QC Description] This is a new problem introduced in Delphi 2007 (and still repro with the Dec2007 update installed):
If Halt is called inside an 'except' or 'finally' block, the current exception's message is forcibly displayed on the screen, and the process returns with an exit code of 1 instead of the exit code specified in the Halt call.
The cause appears to be these lines in SysUtils' DoneException procedure, which are new to Delphi 2007: if ExceptObject <> nil then ExceptHandler(ExceptObject, ExceptAddr);
I assume the intention there is to ensure that any new exceptions raised during termination are brought to the attention of the user.
In my case, however (see the example code), the exception was raised before termination commenced. DoneException should ignore such pre-existing exceptions. And it certainly should not be changing my exit code from 5 to 1.

[QC Description] SysUtils.Abort may cause an AV exception if a call to the Abort is maked from a procedure, that uses EBP as a local variable.
Source for SysUtils.Abort in 2006: procedure Abort; function ReturnAddr: Pointer; asm MOV EAX,[EBP + 4] end; begin raise EAbort.CreateRes(@SOperationAborted) at ReturnAddr; end;
Source in Delphi 4 procedure Abort; function ReturnAddr: Pointer; asm MOV EAX,[EBP - 4] end; begin raise EAbort.Create(SOperationAborted) at ReturnAddr; end;
The defference is that Delphi 4 version has a compiler-generated local variable for loading resource string. So compiler saves old value of EBP and assigns it to ESP.
But in Delphi 2006 resource string is acceessed by a @ reference and there is no need in such a local variable and value if EBP is preserved and it has a value from the calling procedure.
Sometimes it can hold a local variable.

C++ templates permit this but generate complexes errors cases if a type can't use with a template (verifications are do only when the code for a template is creating).
.Net constraints are a good idea but extend them will produce hard reading code : TMyGeneric
So what i propose : a new key word to specifie what kind of type is allowed for the generic. The next C++ standard can also introduce this feature (http://www.open- std.org/jtc1/sc22/wg21/docs/papers/2006/n2081.pdf).
With this generics in Delphi would be as powerfull as C++ template but with a easy to read code.
This new key word would work as interfaces but only at compiling time and could be used with class, record, class helper and record helper.
Exemples of possible use (with a "concept" key word) below.

When editing a unit (not even a form), all these commands remain visible and many of them ("Align...", "Size..." and all below them) are even enabled, although they obviously can't do anything useful in this context.

When a (secondary) form has the PopupMode=pmExplicit and PopupParent the main form, then, if, while the 2ndary form is open, the focus is switched to another program and back, by closing the 2ndary form (which implicitly should bring the focus to the Delphi application), the main form is sent in back to the program which was focused at some moment in time.

[QC Description] Please eliminate all automatic and uncontrollable alpahabetization in Project Manager for all personalities.
Currently in Delphi alphabetization is automatic and enforced at all times. I prefer to keep libs, resource files, etc together at the bottom of the list since I cannot edit thes files in the IDE. Others may wish to group files by topic. PM does not allow reording files at all in the Delphi personality.
In C++, the situation is worse because the order of files in PM controls the build order. User can drag and drop files into a different order, but the files are realphabetized every time a new file is added to the project QC61376 or when the view is changed QC61372.
I would like to see all forced reordering of the PM file list eliminated and optional alphabetization implemented instead.

1. The DataSet is opened at design time. (ie. when we start the app, the DataSet is already Active). 2. Run the application. Add some records. Commit if necesary. Close. 2. We have on the form a TDBRichEdit visible /and/ already bound to a field from above DataSet... 3. (Re)run the app. You'll see that the TDataSet's state is dsEdit. (You can see this by, eg. putting a TDBGrid ...then the DataSet is already in the Edit state when the app starts. and/or TDBNavigator on form or inspecting the property directly in code - something like if DataSet1.State=dsEdit then ShowMessage('problem');). The cause is that Note: The above behavior should be seen also at step 2, but I didn't tested it. a.) We have procedure TDBRichEdit.EMSetCharFormat(var Message: TMessage); begin BeginEditing; inherited; end;
...which is needed in order to save the DBRichEdit's formatting and b.) TCustomRichEdit (the ancestor of TDBRichEdit) has the nasty behavior to send to itself EM_SETCHARFORMAT as a result of its initialization process (if you have time, see TCustomRichEdit.CreateWnd for details). In fact the 'problematic' code is procedure TTextAttributes.SetAttributes(var Format: TCharFormat2); var Flag: Longint; begin if FType = atSelected then Flag := SCF_SELECTION else Flag := 0; if RichEdit.HandleAllocated then SendStructMessage(RichEdit.Handle, EM_SETCHARFORMAT, Flag, Format); end;

Add the following lines (marked bellow with //+) in TDBRichEdit's class interface:
TDBRichEdit = class(TCustomRichEdit) private FCreatingWnd: integer; //+ ... protected procedure CreateWnd; override; //+ ...
...and in the class implementation add: procedure TDBRichEdit.CreateWnd; begin inc(FCreatingWnd); try inherited; finally dec(FCreatingWnd); end; end;

Populate the tree with several nodes. Be sure that at least one node has TTreeView.SaveToFile does not support TEncoding Unicode characters in its caption. I suggest putting the Unicode characters in the first node as the problem will be more obvious. 3. Drop a button on the form - Caption = Save. 4. Write an event handler for the button and [QC Description] call TreeView1.SaveToFile( ) specifying a file name. 5. Drop another button on the form - Caption = Load. 6. There is only one version of the TTreeView.SaveToFile method, and it does NOT take a TEncoding parameter. Write an event handler for the Load button and call TreeView1.LoadFromFile() specifying the same file name from step 4. 7. Run the program. Click the Save button. Check the resulting file. The text is readable by The problem with this is that if the tree nodes contain any Unicode characters in their captions, the resulting file Notepad, but there is no BOM in the file. Next, Click the Load button. The nodes are not correctly loaded and cannot be successfully loaded back into the tree. the tree is corrupted.
The root cause of the problem is in the TTreeStrings.SaveTreeToStream method. This method scans through the nodes of the tree basically creating a string for each node prefixed by a tab character for every level deep in the tree the node is, and followed by a CR-LF to indicate the end of line. Each string is then written to the stream. The correct number of bytes is written because the ByteLength( NodeStr) method is used.
However, what is missing is that since no encoding is used, there is no BOM at the beginning of the file.
So, when you go and use the TTreeView.LoadFromFile method, which calls TTreeStrings.LoadTreeFromStream, there is no BOM in the file, and so the load thinks the data is Ansi data, and this causes the file to be processed incorrectly.
----
One way to solve this problem is to use a temporary string list inside the SaveTreeToStrings method instead of writing directly to the stream. That is, use the temporary string list to build up the list of node items (no need to use EndOfLine because it is in a string list.) Then at the end, use the TStringList.SaveToFile method to save the file. Of course, you would also have to add overloaded methods for TTreeView.SaveToFile and TTreeView.LoadFromFile to accept TEncoding parameters. But these would get passed to the string list method calls. The same is true for the LoadTreeFromStream method, but in that case, the method already uses a temp string list to load the file/stream.

It appears that the comparison tries to compare a UnicodeString and a ShortString without any conversion of either of them. This does not happen if you use, say, 'Hello', instead of '@'.
Take a look at the CPU view:
Project141.dpr.12: P := '@'; 0040A915 B894A94000 mov eax,$0040a994 0040A91A 8945FC mov [ebp-$04],eax Project141.dpr.13: if P <> '@' then 0040A91D 8D45F8 lea eax,[ebp-$08] 0040A920 8B55FC mov edx,[ebp-$04] 0040A923 E850A9FFFF call @UStrFromPWChar 0040A928 8B45F8 mov eax,[ebp-$08] 0040A92B BA98A94000 mov edx,$0040a998 0040A930 33C9 xor ecx,ecx 0040A932 8A08 mov cl,[eax] 0040A934 41 inc ecx 0040A935 E8028BFFFF call @AStrCmp 0040A93A 741B jz $0040a957
As you can see, P is converted to a UnicodeString, and that is passed to AStrCmp as one of the parameters, which is incorrect! The other parameter, the string at address $0040a998, is a short string (bytes 01 40 00).

Our Oracle applications in D2007 use String for *all* fields of all tables and stored procedures, never WideString. I think it's very likely that if you create a Oracle10g database with characterset WE8ISO8859P15 and connect using this client: Just recompiling in D2009 *all* querys and stored procedures fail with type mismatch errors "expecting String actual WideString". http://download.oracle.com/otn/nt/instantclient/10204/instantclient-basic-win32-10.2.0.4.zip
My guess is that D2009 is wrongly identifying our database as Unicode. I don't know how D2009 identifies if an you can reproduce it. Oracle10 database is Unicode-enabled or not, but in our case it must be doing it the wrong way. I think the right way should be something like:
SELECT value FROM nls_database_parameters where parameter = 'NLS_CHARACTERSET'
In our database that query returns WE8ISO8859P15. Unless that query returns UTF8, UTF16... you shouldn't force us to use Widestrings.
For us using Widestrings throughout all our applications, combined with QC 4790 is a real showstopper.
(An alternative solution would be to add a property SqlConnection.UseUnicode with values Always/Never/Default, so users could decide themselves if they want to use WideStrings).

[QC Description] Project Options|Compiling has this:
Long strings by default Delphi for Win32 only. This option (equivalent to the $H directive) controls the meaning of the reserved word string when used alone in a type declaration. The generic type string can represent either a long, dynamically-allocated string (the fundamental type AnsiString) or a short, statically allocated string (the fundamental type ShortString). By default, Delphi defines the generic string type to be the long AnsiString. All components in the component libraries are compiled in this state. If you write components, they should also use long strings, as should any code that receives data from component library string-type properties. The disabled (equivalent to {$H-}) state is mostly useful for using code from versions of Delphi that used short strings by default. You can locally override the meaning of string-type definitions to ensure generation of short strings. You can also change declarations of short string types to string[255] or ShortString, which are unambiguous and independent of the enabled option. Default = True
Which needs updating for Unicode strings. QC Entry 67146 QC #: Date Reported: Area: 67150 9/24/2008 RTL Description: Steps: [QC Short Description] Open the ACLAPI.pas and check the declarations of any of the functions. Incorrect Declaration for multiple functions in ACLAPI library

I'm not sure if the same is also needed for the SaveToFile, since that seems to work fine. Cause: TTreeView LoadFromFile, implemented as TCustomTreeView.LoadFromFile has no Encoding parameter and calls TCustomTreeView.LoadFromStream which in turn calls TTreeStrings.LoadTreeFromStream, again passing no Encoding.
LoadTreeFromStream uses a List.LoadFromStream, passing no Encoding (this is the place where an Encoding could be passed).

Make sure you bring out a "Event Log" debug window to trace how the database connection dll is loaded in the DBXCommon.pas about the property: and unloaded. 6. Press Button1 to open the database connection, the Event Log windows will show database connection library has loaded. 7.

Close the application will only unload the database that use the driver." connection library.
I expect setting the property to true will make the database connection library to be unloaded when connection is closed.
However, I find no way to activate this function thru current DBX4 implementation.
After tracing the DBX source code, I found the cause of the problem. The Dynalink Driver class has the following constructor: constructor TDBXDynalinkDriver.Create(DBXDriverDef: TDBXDriverDef; DBXDriverLoader: TDBXDynalinkDriverCommonLoaderClass); begin inherited Create(DBXDriverDef); FDriverLoaderClass := DBXDriverLoader; // '' makes this the default command factory. // AddCommandFactory('', CreateDynalinkCommand); if (DriverProperties = nil) or not DriverProperties.GetBoolean(TDBXPropertyNames.AutoUnloadDriver) then CacheUntilFinalization; end;
To make AutoUnloadDriver work as it should, the clue is to avoid invoke CacheUntilFinalization in the constructor. In order to do that, we must make sure DriverProperties is not nil and AutoUnloadDriver property has value "True".

QC #: Date Reported: Area: 68068 10/18/2008 VCL\Standard Controls\TListBox Description: Steps: [QC Short Description] - Select File -> New -> VCL Forms Application from the menu. - Put a ListBox on the form. - Insert this code to Missing test in TListBoxStrings.Insert, causes the box to lose object the OnCreate event handler of the form. ListBox1.Items.InsertObject(-1, 'SomeString', Self); Assert (ListBox1.Items.Objects[ListBox1.Items.IndexOf('SomeString')] <> nil, 'Object is nil'); Expected: nothing [QC Description] happens Actual: assertion fails. If you execute code like "aListBox.Items.InsertObject(-1, 'SomeString', aObject)" the string 'SomeString' is happily inserted to the list box but the object is lost.
The cause for this is ; TListBoxStrings.Insert does not test for a condition of Index being -1, since it is perfectly legal to send LB_INSERTSTRING with -1. But TListBoxStrings.PutObject tests if Index is -1 and silently exits if it is. (It is still legal to send LB_SETITEMDATA with -1, but I think the programmer would have thought this would have an undesirable outcome). The correct approach should be to override InsertObject and make the "-1" test there, or, allow "-1" to be Item Index as there is nothing wrong with this with WinApi.
It is not common to call InsertObject with -1 but it occurs with drag-drop list boxes if you drop an item too near to the bottom of the box.
Note: Hunting for bugs like this is really difficult as it really occurs very infrequently and seemingly randomly, _and_ however you are prepared for error logs and else you won't have any logs of mouse coordinates or visuals when the exception log is posted to you. This one has haunted me a little too long.
More Info: I further pursued the matter, and found out that the reason of the bug is exactly as I commented to Mr. Tomohiro Takahashi. To duplicate it here;
While you are dragging an object, the existence of a valid drop target is determined by controls.DragFindTarget. DragFindTarget calls DragFindWindow, and it calls "WindowFromPoint" with the current mouse coordinates. So if you have a WinControl under the pointer, you have a valid Target.
Since we are inserting an object to a ListBox we call ItemAtPos function of the ListBox to find out the position to insert. We pass False to Existing, since -the documentation states- "If Existing is set to false, ItemAtPos returns the index of the last item in the list box plus one." Even if there are no items in the box it will return 0. Fine, we can insert there.
TCustomListBox.ItemAtPos executes a test in the very beginning of the procedure and returns -1 if the test fails. This test is "if PtInRect(ClientRect, Pos) then". Notice the "ClientRect" in the test. A standard List Box has *2* pixels width/height of NonClientArea at its edges. (This is on W2K, other OS or theming can slightly change the area). So it is perfectly possible, though rare, a user at times can drop his item at the very edge; where we have a valid Target, but ItemAtPos, despite the documentation and design, returns -1. And, when we execute ListBox.Items.InsertObject, we have our string inserted, but not our *Object*.
I have attached a project which clearly demonstrates the bug at large. (Please don't run it in a VM. At least Virtual PC does seem to override the default mouse behaviour.) Regards.

ReceiveText sets result string length by internally called ReceiveBuf, and ReceiveBuf returns byte length, not Char length.
By this wrong type of ReceiveText result, the data read from ReceiveText is broken.

TLabel is not painted on a themed, double-buffered TTabSheet in Vista 3) Add one TTabSheet to the page control. Set TTabSheet.DoubleBuffered := True; 4) Drop TLabel on the TTabSheet. TLabel will not be visible. Setting DoubleBuffered to False makes the label visible again. [QC Description] In Windows Vista, when enabling runtime themes in a project, all labels placed directly on a TTabSheet control which has DoubleBuffered property set to True will be invisible.
I'm not an expert on internals of VCL, but looking at WM_PAINT handler of TWinControl, there is the following code: if not FDoubleBuffered or (Message.DC <> 0) then ... else begin if DwmCompositionEnabled then begin // Use DWM methods when in Vista DC := BeginPaint(Handle, PS); try PaintBuffer := BeginBufferedPaint(DC, PS.rcPaint, BPBF_COMPOSITED, nil, MemDC); if PaintBuffer <> 0 then try Perform(WM_ERASEBKGND, MemDC, MemDC); Perform(WM_PRINTCLIENT, MemDC, PRF_CLIENT); if not (Self is TCustomForm) then BufferedPaintMakeOpaque(PaintBuffer, PS.rcPaint); finally EndBufferedPaint(PaintBuffer, True); end; finally EndPaint(Handle, PS); end; end else begin // Draw in memory when not in Vista // .. Perform(WM_ERASEBKGND, MemDC, MemDC); Message.DC := MemDC; WMPaint(Message); Message.DC := 0; // ... end; end;
So when not in Vista, WM_ERASEBKGRD and WM_PAINT messages are sent while in other OSes WM_ERASEBKGRD and WM_PRINTCLIENT are sent.
As I understand, child controls are drawn in WM_PAINT, not in WM_PRINTCLIENT so TLabel is never drawn.

But if invoke TParams.AsBytes it would return a TBytes of length 8. P := TParams.Create; try This create a problem in procedure SetQueryProcParams of SqlExpr.pas: Q := P.CreateParam(ftBlob, 'Blob', ptInput); Q.Value := 'TEST'; procedure SetQueryProcParams(const Sender: TSQLConnection; const Command: TDBXCommand; const Params: TParams; ProcParams: TList = nil); i := Q.GetDataSize; begin j := Length(Q.AsBytes); ... finally ftBlob, ftGraphic..ftTypedBinary,ftOraBlob,ftOraClob: P.Free; begin end; Buffer := TDBByteBuffer.Create(Param.GetDataSize); end; Buffer.Append(Param.AsBytes); ExtractedBytes := Buffer.GetBytes; variable i return 4 Value.SetDynamicBytes(0, ExtractedBytes, 0, Length(ExtractedBytes)); variable j return 8 end; ... end;
Invoke "Buffer.Append(Param.AsBytes)" will always raise ERangeError exception with message 'CheckSpace'.
The reason is simple. Buffer is allocated 4 bytes of space but we later append 8 bytes of data to it and thus the ERangeError was raised.
I am not sure if this is a bug or it is by design. Should we let the program decide the encoding of string data store into a blob field? If we let the program decide, the blob field data may not accessible by legacy program that always treat the blob field string data as ANSI encoding.

Read of address 006B0073' Adding a TRibbon control (no panels/groups etc) to a single form application that contains an ActionManager component raises an access violation exception when attempting to execute a rave report.
The error may also be dependent on the presence of a network printer (in my case called: 'LaserJet 1329 on ARGSRV1'). I have seen other reports relating to Rave failures and printers (mainly concerning a crash when trying to invoke the rave editor). However, this problem can be rectified by removing the ribbon component and the ribbon units from the uses clause.
NB. Just deleting the Ribbon and setting the ActionManager style back to standard does not remove the problem. To remove the problem, the Ribbon and RibbonLunaStyleActnCtrls units must also be removed from the uses clause.
Also: a simple application with only a single ribbon control, a rave project component and a button (to action the report) will allow the rave report to execute correctly, even if the network printer is in place. However, if I add DBGrids into the main form uses clause, the same access violation exception occurs.
It seems to me that a conflict is occurring at a fairly fundamental level.

QC Entry 69413 QC #: Date Reported: Area: 69432 11/29/2008 Database\Data Access Controls\TTable Description: Steps: [QC Short Description] I tried the following The GetPAnsiChar is as follows function GetPAnsiChar(const S: string): PAnsiChar; begin if Error opening table when field has a DefaultExpression S <> '' then Result := PAnsiChar(AnsiString(S)) else Result := ''; end; But if I replace the original line with this: StrCopy(ADataSources.szSQLExprImport, PAnsiChar(AnsiString(Field.DefaultExpression))); Then the error [QC Description] doesn't occur any more and ADataSources.szSQLExprImport always contains a valid value (FALSE in my There seems to be an issue with the GetDefaultExpression function in the TBDEDataSet.ConstraintCallBack case) Now, this looks to me to be doing exactly the same thing but I think something is going wrong when function in the DBTables unit. calling GetPAnsiChar instead which causes it to return the corrupt string. I've spent ages trying to replicate it outside the main application but cannot do so. It only raises the error when I run the big application with lots of I was getting the following error when opening the TTable which has persistent fields and two of them tables/queries open If pushed I could probably send you a screen vid of the situation happening in the (TBooleanFields) have a DefaultExpression set to FALSE. debugger.
"Preparation of field default failed. Token not found. Token: €€€€€€Ì << these look like euro symbols and accented characters Line Number: 1"
I traced into the above function and found that after calling this line:
StrCopy(ADataSources.szSQLExprImport, GetPAnsiChar(Field.DefaultExpression));
The value in ADataSources.szSQLExprImport is all corrupt characters.
If I remove the DefaultExpressions from the two fields, the table opens without error.
I cannot replicate this in a simple test project but within a large application with several tables, queries, datamodules, etc. the error happens every time. The strange characters can vary each time though.
This worked fine under D2007

The fix is to add the following line (as last line in method) to the TRibbonTextControl.CalcBounds method.

Execute the open dialog from the TOpenPictureDialog raises EInvalidGraphic on selecting a LNK file (single click) button. Run the application, click the button, use the open dialog to browse to a *.lnk file and single-click that file. You should now get a EInvalidGraphic exception. [QC Description] I get a "Debugger Exception Notification" dialog when selecting or highlighting a *.LNK link file in a TOpenPictureDialog dialog. Exception notification message: Project Project1.exe raised exception class EInvalidGraphic with message 'Unknown picture file extension (.lnk)'.
Open dialog options seem to be ignored, such as the ofNoReadOnlyReturn option. Same exception regardless of options.
If I click Continue on the exception notification dialog, my application continues as if nothing had happened. I have to select the LNK file again to reach its target, which happens without any further exceptions.
The preview feature of TOpenPictureDialog may be what causes the exception. QC Entry 69533
(SB) Note: The exception only occurs when debugging, not at runtime. QC #: Date Reported: Area: 69555 12/3/2008 Database\DataSnap\Server Description: Steps: [QC Short Description] 1. Create a datasnap 2009 application 2. use the invocation lifecycle 3. enable reportmemoryleaksonshutdown "Invocation" life cycle leaks memory or debug the application
[QC Description] If you use the "Invocation" life cycle in a Datanspa 2009 server, the destruction code doens't free the object (created for each request) unless you manually handle the OnDestroyInstance event handle of the Server class and destroy the instance.
I have a demo (also in my book) that shows this.
This is quite significant: every single invocation leaks the server side object (which can as well be a data module!)

I expected to find something along the lines of:
"StartsStr determines if the substring ASubText begins the string AText using a case sensitive algorithm. If ASubText matches the beginning of AText, the result is true, otherwise it is false."

[QC Description] The method System.Val should set the Code output parameter to 1 if the supplied string is empty.
However since Unicode was introduced (Delphi 2009) the floating point version of Val now sets the code parameter to 0 - implying that the string is a valid number, which it is not.
I've marked this type 'B' because it has caused us dozens of bugs, including databases returning invalid reports because the user input was misinterpreted.
I believe that the bug is in _ValExt in System.pas line 9252 (just after @@Empty label).

Further more there is a check in that function ... 10574: if FPanels.Count = 0 then ... which is pointless because a Panel was just added to the list and Count will always be > 0.
A corrected version should look something like this: procedure TCustomCategoryPanelGroup.InsertPanel(Panel: TCustomCategoryPanel); var LPanel: TCustomCategoryPanel; begin FPanels.Add(Panel); Panel.FPanelGroup := Self; if FPanels.Count = 1 then // Modified was 0 Panel.Top := 0 else begin LPanel := TCustomCategoryPanel(FPanels[FPanels.Count - 2]); // Modified was [FPanels.Count - 1] Panel.Top := LPanel.Top + LPanel.Height + 1; end; Panel.Left := 0; Panel.Align := alTop; Panel.Alignment := FHeaderAlignment; if not (csLoading in ComponentState) then AutoScrollInView(Panel); end;
[Edit1] Note that the current sort/compare function inverts the list of CategoryPanels.
{$IF DEFINED(CLR)} function ComparePanels(Item1, Item2: TObject): Integer; {$ELSE} function ComparePanels(Item1, Item2: Pointer): Integer; {$IFEND} begin Result := TCustomCategoryPanel(Item2).Top - TCustomCategoryPanel(Item1).Top; if Result > 0 then TCustomCategoryPanel(Item2).PanelGroup.FReorderPanels := True; end;
To make the above change of InsertPanel() more reliable the "compare line" should be changed to ...
Result := TCustomCategoryPanel(Item1).Top - TCustomCategoryPanel(Item2).Top;
... first reaction is that the following line should also be changed to ... if Result < 0 then
... but without further testing that complete statement looks a little strange in a QuickSort algorithm ;-) QC Entry 70197 QC #: Date Reported: Area: 70221 1/2/2009 SOAP Description: Steps: [QC Short Description] 1.

[QC Description] The left of the first character is often clipped. The error is generally only one pixel, but it can be a problem especially with charcters with diacriticals.
The problem is also present in TBitBtn.
A standard capital T in Tahoma at 8 point is visibly assymetrical. A character that demonstrates the issue well is a lower case latin small letter I with diaeresis (U+00EF). The left hand dot above the vertical line is generally lost.
The effect is visible with or without themes.
The code measures the required size for the text using the OS DrawText call, and uses the returned rectangle to set the size of a clipping rectangle when displaying it.
It seems the OS clips the text. From the SDK documentation for DrawText: "Note that text with significant overhang may be clipped, for example, an initial "W" in the text string or text that is in italics." There is no matching comment in DrawThemeTextEx which is also used in some circumstances, but it seems to have the same issues as DrawText.
Standard Windows buttons do not suffer the effect.
Possible solutions would be to expand the measured rectangle slightly or to add a DT_NOCLIP flag in the DoDrawText calls in TButtonGlyph.DrawButtonText (Buttons.pas).
The problem was present back in Delphi 7, but was not generally seen because it depends on the font. D7 normally uses MS Sans Serif - and the fault does not show with that, but changing the font to Tahoma makes it perform just the same as current versions of Delphi.

Compile and run the attached application. 2. Click the button "Bad IsNull" The normal memory manager does not detect this, so you will see spurious artifacts in your applications. Only the FastMM memory manager in full debug mode detects it reliably. Expected: no error This bug occurs frequently when the datasizes of the underlying DB have changed, but the persistent fields in the application have not yet been corrected yet. Actual: FastMM has detected an error during a FreeMem operation. The block footer has been corrupted. As the IDE has no way of automatically correcting the datatypes of persistent fields, and this error is hard to detect, I have rated it quite high to fix. Notes: The attached application reproduces the issue. It includes FastMM as that is the only way to reproduce it. A. the buttons "Good Value" and "Good IsNull" are to demonstrate that using a persistent TIntegerField works fine The queries in the application accesses the employee.gdb demo database that ships with any Interbase version: B. the button "Bad Value" is to demonstrate that using a persistent TSmallintField for obtaining the Value works fine too Select Max(SALES.QTY_ORDERED) From SALES
The bug can be reproduced with any query returning an integer field; this particular example is just to make it easy to reproduce.
The bug manifests itself when you use Persistent Fields that are of the wrong size.
The expected behaviour is to get some kind of size warning, or an overflow. The actual behaviour is a memory overwrite that can be detected by FastMM.
The solution to resolve the issue is simple
The accompanying application contains two queries: BadSQLQuery and GoodSQLQuery both contain persistent fields: object BadSQLQueryMAX: TSmallintField FieldName = 'MAX' end object GoodSQLQueryMAX: TIntegerField FieldName = 'MAX' end
Behaviour: - obtaining BadSQLQueryMAX.Value: value will overflow - obtaining BadSQLQueryMAX.IsNull: memory overwrite occurs
The cause of the memory overwrite is that: - TField.GetIsNull calls GetData(nil) - The actual field now allocates a buffer that is too short - The actual TDataSet now overwrites this buffer with a value of the native size
Obtaining BadSQLQueryMAX.Value does not generate a memory overwrite because: - TSmallintField is derived from TIntegerField - TIntegerField.GetAsInteger calls GetValue(Result) - the Result os if size LongInt which is large enough to hold the result
Hence the proposed workaround is to introduce TIntegerField.GetIsNull that mimics TIntegerField.GetAsInteger behaviour:
{ Proposed workaround: add the below GetIsNull method to TIntegerField
//MMWIN:MEMBERSCOPY unit _MM_Copy_Buffer_; interface type TIntegerField = class(TNumericField) protected function GetIsNull: Boolean; override; end;
implementation function TIntegerField.GetIsNull: Boolean; var Dummy: LongInt; begin Dummy := -1; Result := not GetValue(Dummy); end;
end. } QC Entry 70499 QC #: Date Reported: Area: 70521 1/14/2009 Database\Data Aware Controls\TDBGrid Description: Steps: [QC Short Description] 1. Open the attached project 2. Start the project (This will copy '12.12.08' into the clipboard) 3. Click into the DBGrid-InplaceEditor ignores pasted text FLD_DATE field in the grid (show inplace editor) 4. Paste the clipboard text into the control by pressing Ctrl+V 5. Use TAB, ENTER or the mouse to leave the edit mode Expected: '12.12.08' is now in the field. Actual: The [QC Description] field is still empty. The DBGrid InplaceEditor ignores text that was pasted from the clipboard if the field has an EditMask.
This is because the TCustomMaskEdit overrides the WM_PASTE (and WM_CUT) message handler and if as mask is specified, the default handler isn't called. The default handler sends a WM_COMMAND(EN_CHANGE) to the parent but without calling the default handler this message isn't sent to the DBGrid and the content of the edit is never copied to the internal InplaceEdit text field.

It also hangs when reading a Unicode stream with DetectBom = False:
SR := TStreamReader.Create(MS, False);
Try changing MyString in the steps to: MyString2 = #$1FFFF + mystring;
This does not hang indefinitely, but takes very long to read. This is probably invalid for UTF8, but it should come to that conclusion much sooner.

QC Entry 70869 QC #: Date Reported: Area: 70899 1/27/2009 VCL\Printing Description: Steps: [QC Short Description] procedure TPrinter.SetToDefaultPrinter; var [...] DefaultPrinter: array[0..1023] of Char; [...] I := SizeOf Possible buffer overrun in GetDefaultPrinter (DefaultPrinter); GetDefaultPrinter(DefaultPrinter, I); Possible solution: I := Length(DefaultPrinter); if not GetDefaultPrinter(DefaultPrinter, I) then FillChar(DefaultPrinter, SizeOf(DefaultPrinter), #0); [QC Description] There is a possible buffer overrun in the call to GetDefaultPrinter. Apart from memory corruption, this could crash the application with a DEP (data execution prevention) error.
GetDefaultPrinter expects the Length of the buffer in TChars. The current implementation is passing the *size* of the buffer.
Therefore change the following line in Printers.pas
I := SizeOf(DefaultPrinter); to
I := Length(DefaultPrinter);
Also the result of DefaultPrinter must be checked. If the function fails, the content of DefaultPrinter is undefined. In this case there is not even a guarantee that there is a terminating #0 character. DefaultPrinter returns an error if there is no printer installed (as expected).
[Update] The documentation of GetDefaultPrinter in the Windows SDK says that the size is in "characters". This would have been clearer if it had said "tchars", because that is what the function expects. A little test confirms that characters refers to tchars indeed. QC Entry 70899 QC #: Date Reported: Area: 70905 1/27/2009 Database Description: Steps: [QC Short Description] Search in the RTL/VCL code for all 'VString' occurances. Notice that in Variant.pas all TVarData.VString are TVarData.VString interpreted as UnicodeString, while it contains a pointer to an AnsiString cast to an AnsiString. Now notice that DBCommon (and other units) do a cast to 'string', which effectively means a cast to 'UnicodeString'. [QC Description] A search in DBCommon for the symbol 'VString' (a member of TVarData), results in 8 occurances of this construct : "string(TVarData(Value).VString)".
Since 'string' now means UnicodeString, this construct interprets an AnsiString as UnicodeString, without any compiler magic in between.
Possibly the new string-header helps preventing errors, but at the very least this is a syntactic error.
PS: Don't mix this up with TVarRec.VString: PShortString, it's TVarData.VString: Pointer that's handled wrong.

[QC Description] When a datasource has it's AutoEdit property set to false, various edit controls (TDBMemo, TDBEdit, etc) are not respecting the AutoEdit setting.
With AutoEdit = false: Upon entering text (which they shouldn't allow you to do without first going into edit mode), they do not put the dataset into edit state (as expected) but they do allow you to enter text (not expected). Then, moving focus to another control raises a 'Dataset not in edit or insert mode' exception.

QC Entry 71082 -sTest_AS_DataRequest.
Server: Setup a basic DataSnap server with a TSQLConnection, TSQLDataSet, and TDataSetProvider (and TDSServer, TDSServerClass, TDSTCPServerTranspot for DataSnap 2009 connectivity).
Add an event handler for TDataSetProvider.OnDataRequest to do something simple, like setting the result to the input parameter.
Client: Setup a basic DataSnap client with a TSQLConnection, TDSProviderConnection, and TClientDataSet. Hook everything up so the data set gets data from the data set in the server.
Call TClientDataSet.DataRequest. The server will throw a variant exception.
Cause: The problem appears to be in DSServer.pas:TDSProviderDataModuleAdapter.AS_DataRequest. The local Data: OleVariant variable is being assigned DataStream.AsVariant. The problem is that DataStream is already an OleVariant, and Variants evidently don't know how to convert themselves to a Variant. :)
Seriously though, this results in Variants.pas:_DispInvoke being called against the DataStream variant. _DispInvoke doesn't know how to handle basic variant types (like varInteger and VarOleStr), so FindCustomVariantType fails to find a handler, and VarInvalidOp is called.
The problem is solved by changing this line in DSServer.pas from: Data := DataStream.AsVariant; to Data := DataStream;
Or, alternatively, remove the local Data variable completely and change this line:
Result := FProviderDataModule.Providers[ProviderName].DataRequest(Data); to Result := FProviderDataModule.Providers[ProviderName].DataRequest(DataStream);

Faulty handling of FModified in XMLDoc.pas
[QC Description] Local variable FModified is an integer that is incremented for each modification. In SaveToXMLStrings FModified is compared with FXMLStrRead to see if the xml text property should be refreshed. (FModified <> FXMLStrRead) SaveToXMLStrings sets FXMLStrRead := FModified when it is done.
So FXMLStrRead variable retains the value for FModified when the xml text property was last refreshed.
When you save the document to file FModified is reset to 0 and starts to count upwards again for each modification.
This means that when FModified again reaches the exact same value that FXMLStrRead has, the xml property will not be refreshed in SaveToXMLStrings.

QC #: Date Reported: Area: 72558 3/29/2009 RTL\Delphi\RTL Exceptions Description: Steps: [QC Short Description] Demonstrated in the attached projects. Unloading DLL breaks exception handling in host application (JJS: The crash described does not occur when using the IDE. The executable should be run on its own or in [QC Description] the IDE via "Run without Debugging") When a Delphi host application raises an exception, and then unloads a Delphi DLL within a nested exception handling clause (Try ... Finally ... Except), the exception object gets "hijacked" and destroyed by the DLL unloading procedure, causing the host application to crash.
For example, the following program crashes at step 4 with an access violation:
Try 1. Load the DLL; Try 2. Raise Exception.Create('Ooops!'); Finally 3. Unload the DLL; End Except On E:Exception do 4. Print Exception message; End
The problem seems to be caused by the "exception stack cleaning" code in the Halt0 procedure of the System.pas. This code blindly acquires and frees all outstanding exceptions. When executed during the DLL unloading, it frees the exception object prematurely, leaving the host application in step 4 accessing a piece of freed memory.
The suspect code segment is also referred to in QC#72439.
The problem only happens when building DLL and host application with packages.

The problem occurs when a TWideStringField is used in the server side TClientDataset. The unicode string is broken when sent from the server to the client. I believe it happens in the routine that builds the data packet on the server side.

TParam.GetAsAnsiString consists of the following code: function TParam.GetAsAnsiString: AnsiString; begin if VarType(FData) = vtAnsiString then Result := AnsiString(FData) else Result := AnsiString(GetAsString); end;
Since FData is declared as a Variant instead of a TVarRec, the first condition is never met. This results in UTF8 encoding being lost.

The changin of the property is somewhat random. Sometimes, when saving TComboBox "randomly" saves ItemHeight = 13 and ItemHeight = 0 into the DFM a .dfm, the value is not changed. Thre steps might be something like this: - Create a VCL forms application and add a few TComboBoxes to the form - Save it to disk - Close the IDE - Check the value of [QC Description] TComboBox.ItemHeight in the .dfm - Reopen the IDE and project - Modify the form and save it - [Some other I review .dfm files for changes before checking them in, and I often see a form with a TComboBox ItemHeight steps might be required here, but it is unclear] - Go back to step "Close the IDE" and recheck until the property changing from 13 to 0 and back to 13 over the course of a few days without actually changing that ItemHeight value changes Maybe the issue is worse with forms involved in visual form inheritance, but maybe property (or any property on the combobox). The problem happens under both XP and Vista and has been not. The issue is discussed some more here: https://forums.codegear.com/thread.jspa?messageID=11734 happening since at least Delphi 2007.
The reason might be quoted here: "In the VCL source files, FItemHeight is set to "16" in the constructor (TCustomComboBox.Create), but the property's read method retrieves the ItemHeight by performing CB_GETITEMHEIGHT windows message: function TCustomComboBox.GetItemHt: Integer; begin if FStyle in [csOwnerDrawFixed, csOwnerDrawVariable] then Result := FItemHeight else Result := Perform(CB_GETITEMHEIGHT, 0, 0); end;

[QC Description] If I'm using a dbx3 driver in Weaver (build 3417) datatypes do not seem to be mapped to the correct functions in my dbx3 driver via dbxadapter.dll - for example if I try to retrieve a INTEGER value from the database, the getDouble routine in my driver is called. This all worked fine in D2009.
Is there a wrong mapping introduced in the new dbxadapter.dll ? It seems to me that TDBXDataTypes and TFieldType were mixed - for example ftInteger is 6 in "driver land" and TDBXDataTypes, but 6 is ftDouble in TFieldType.
I can trace in sqlexpr.pas that the correct value of 6 (ftInteger) is used when DBXRow_GetFixedBytes is called, DBXRow_GetFixedBytes calls into dbxadapter where I have no source of and then this calls the GetDouble routine in my driver.

QC #: Date Reported: Area: 74889 6/15/2009 Debugger\Evaluator\Delphi Description: Steps: [QC Short Description] Inspecting a string with quotes doesn't work properly
[QC Description] When you inspect a string in the debugger, if the string has single-quote characters, the debugger doesn't show a proper Delphi string literal -- it refuses to double-up the quotes. For example... s := 'abc''xyz';
If we inspect s after running the above statement, the debugger shows...
'abc'xyz'
Perhaps this is "easier to read", but it causes some serious problems...
1) You can't copy-and-paste from here into a source code unit (or other tool that expects a literal). 2) It breaks the "modify" part of the Evaluate/Modify dialog -- in the sense that Evaluating the invalid string is placed into the "New Value" edit. For example, if we evaluate "s" above, then hit the "Modify button, then s will be trucated to just 'abc'. 3) It is ambiguous, in many cases. For example, if the Evaluate command shows the following string: 'a'#9'b' then there are actually to real strings that could be behind this: 'a'#9'b' and 'a''#9''b'.

[QC Description] The current implementation of interactive gestures makes it impossible for a control to receive mousemove messages coming from Windows 7 touch if a parent control uses an interactive gesture. This is quite a problem since TScrollingWincontrol sets TouchManager.InteractiveGestures to [idPan].

[QC Description] The current interactive gestures implementation has a feature that's a bit unfortunate. Gesture events can't be forwarded to the control's parent is the control implements a gesture itself.
Let's say we have a TButton which is on a TScrollBox. For some reason the button responds to igPressAndTap. Now igPan no longer works on the button, so you can't pan the scrollbox in that area, which probably isn't what you want.

[QC Description] Object reference not set to an instance of an object.
- Created new VCL Forms project - Opened RTTI.pas - Scrolled around in it for a while... moved the mouse over it a couple of times (just looking at the interface section for TValue) - boom
Did some more testing, it's specifically this line: function Cast
[QC Description] Some field types are missing in a couple of places in DbCommon.pas: function IsNumeric(DataType: TFieldType): Boolean; is missing support for ftLongWord and ftExtended function TFilterExpr.PutConstant(Node: PExprNode): Integer; is missing support for ftLongWord and ftExtended. It also might fail with ftAutoInc if it's mapped to a TUnsignedAutoIncField and a constant value > High(Integer) is passed. ftLongWord should map to fldUINT32 ftExtended should map to fldFLOATIEEE procedure TExprParser.TypeCheckArithOp(Node: PExprNode); should probably be a bit more careful in the IsNumeric() and IsNumeric() case. e.g. if one of the operands is an extended, the result should be an extended too.
I've rated this as a critical error because as long as this is not fixed, it's not possible to use TExprParser for any filter which compares a ftLongWord or ftExtended against a constant value (parser bombs out with an exception, no filter expression is being created).

AV error filling out old-style object descendants See the following program output indicating failure. [QC Description] Now this is yet another object bug in the implementation of legacy objects in Delphi 2009. The following code, FAIL - Exception Error which worked in previous versions of Delphi, will generate an access violation: ClassName=EAccessViolation Message=Access violation at address 004121A5 in module 'BTS270422.exe'. Read of address FFFFFFF8 program Project8;

type var TTest=object(TTestBase) T:TTest; end; begin try ZeroMemory(@T,SizeOf(T)); var except T:TTest; on E:Exception do begin Writeln(E.Classname, ': ', E.Message); try end; ZeroMemory(@T,SizeOf(T)); end. WriteLn('PASS'); except Strangely enough the following code will work: on E:Exception do begin program Project8; WriteLn('FAIL - Exception Error'); Writeln(' ClassName=', E.Classname); {$APPTYPE CONSOLE} WriteLn(' Message=', E.Message); end; uses end; Windows, end. SysUtils; type TTestBase=object X: Integer; end;
//type <-- The two objects are declared in the same ?type declaration block?. TTest=object(TTestBase) end;
var T:TTest; begin try ZeroMemory(@T,SizeOf(T)); except on E:Exception do Writeln(E.Classname, ': ', E.Message); end; end.
This however does not solve my problem as my objects are defined in several different units.
I simply don?t understand why Embarcadero (or whoever they are) simply doesn?t drop support of the legacy object type all together or get backwards compatibility fixed ASAP. In almost every version since Delphi 2 some behavior of the legacy objects have changed or been declared illegal and the implementation of it in Delphi 2009 seems to be one huge bug.
Too bad for an otherwise great product. QC Entry 75212 QC #: Date Reported: Area: 75215 6/24/2009 VCL\Touch Controls\TTouchKeyboard Description: Steps: [QC Short Description] TTouchKeyboard: customize background colors
[QC Description] If a TTouchKeyboard is on a form, but it doesn't fill the whole client area, the background gradient may not look good. It doesn't if the form is black, for example.
A way to change the colors would be convenient. A virtual PaintBackground(c: TCanvas) method could be added, for example. Alternatively the top/bottom gradient colors could be public or published properties. QC Entry 75215 QC #: Date Reported: Area: 75216 6/24/2009 VCL\Touch Controls\TTouchKeyboard Description: Steps: [QC Short Description] TTouchKeyboard: button margin issues
[QC Description] - There isn't a margin between rows. - In the Standard layout the up and down arrow keys don't align. This probably happens because the "Fn" doesn't have a margin on its righthand side. - There's a margin in the righthand side of the keyboard. The other sides don't have a margin. - There's a 2 pixel margin between buttons which doesn't respond to mouse/touch clicks. It's better to avoid these inactive areas, so the user won't wonder why the program doesn't respond to pressing buttons. Note that the Windows 7 keyboard doesn't have inactive areas between buttons.
It would look better if all buttons had the same margin (1 pixel) on all four sides. Modifying the FindButton function to remove the inactive areas would then be easy.

[QC Description] It is very look like debug system.dcu was compiled from another pas unit then present in source directory. Because I very often see misplaced dots which mean the line was linked to binary, and debugging often was unable because position of the debugger was not the real source position.
So I recompiled the system unit, replaced original one and problems has gone.

[QC Description] In TBitmap.WriteStream the following code is always called:
Canvas.RequiredState([csHandleValid]); Save := GDICheck(SelectObject(FCanvas.FHandle, FDIBHandle)); ColorCount := GetDIBColorTable(FCanvas.FHandle, 0, 256, Colors); SelectObject(FCanvas.FHandle, Save);
The documentation to GetDIBColorTable states:
Remarks The GetDIBColorTable function should be called to retrieve the color table for DIB section bitmaps that use 1, 4, or 8 bpp. The biBitCount member of a bitmap associated BITMAPINFOHEADER structure specifies the number of bits-per-pixel. DIB section bitmaps with a biBitCount value greater than eight do not have a color table, but they do have associated color masks. Call the GetObject function to retrieve those color masks.
So calling GetDIBColorTable will always return 0 for any bitmap with > 8bpp, making this code useless for any >8 bpp bitmap.
I've found that, at least with current (186.18) nVidia drivers under Windows 2008 and with large bitmaps (6090x1682 in my case) the SelectObject call regularily fails (returns 0, but GetLastError also returns 0) and is followed by a BSOD a couple of seconds later.
Given that the code in question is just a waste of time and resource for >8bpp bitmaps anyway, it should be changed to: if FDIB.dsbmih.biBitCount <= 8 then begin Canvas.RequiredState([csHandleValid]); Save := GDICheck(SelectObject(FCanvas.FHandle, FDIBHandle)); ColorCount := GetDIBColorTable(FCanvas.FHandle, 0, 256, Colors); SelectObject(FCanvas.FHandle, Save); end else ColorCount := 0;
Not only does that prevent the BSOD (which admittedly would appear to be a driver bug that's causing kernel mode memory overwrite), but it generally speeds up saving of TBitmap's QC Entry 75498 QC #: Date Reported: Area: 75515 7/3/2009 Compiler\Delphi\Generics Description: Steps: [QC Short Description] Download the attached project and try compiling it.

[QC Description] TTouchKeyboard doesn't respond to pen. This is caused by the "if not IsPenEvent(GetMessageExtraInfo) then" code.
Also, the keyboard won't work on modern touchscreen computers running Vista because GetMessageExtraInfo will return "pen" or "touch" hence mouse messages won't be processed.

This problem occurs frequently in our environment when updates to third-party packages cause package dependencies to become broken (e.g. Package A depends on Package B and an updated version of Package B is installed).
After a component update (e.g. installing a new version of DevExpress), the IDE emits a shower of "Cannot load package..." errors as each broken package fails to load. Responding "No" to disable future loading of the offending packages avoids a repeat of the same errors when a project is opened. The problem occurs when attempting to re-enable the packages after the broken packages have been opened and re-compiled.

[QC Description] When you select some text in the editor and press Ctrl-F, the search bar at the bottom appears and holds the selected text as the text to search for.
It also turns on the "search selection" checkbox. (Which is similar to D2009 behaviour), but if you then press F3 to search for the next occurence, you get dialog boxes "tried to search selected text, but no text was selected".
In previous versions the "search selection" was cleared when the selection in the editor was cleared according to Darren Kosinski in the newsgroups (weaver.ide.editor).

[QC Description] The following code in StdCtrls.pas (around line 3947) was changed from this... if HasSelectedText(StartPos, EndPos) then SaveText := Copy(FFilter, 1, StartPos) + Key
To this (around line 4031) ...
// This call sets StartPos and EndPos HasSelectedText(StartPos, EndPos); if StartPos < Length(FFilter) then SaveText := Copy(FFilter, 1, StartPos) + Key + Copy(FFilter, EndPos+1, Length(FFilter))
I reformatted it slightly for word wrapping. Anyway, I'm not quite sure what the intention of the new code is, but I have determined that it breaks the original behavior of the combo box (this code is in the KeyPress method). Here's how.
Suppose the combo box has 4 items: Answer Apple Banana Pie
And suppose that the Style is csDropDownList. In Delphi 2009, if you type "ap" quickly, then you will be taken to "Apple". In the latest Weaver, no matter how quickly you type "ap", you will be taken to "Pie". The "a" takes you to "Answer", as desired, but the "p" takes you to "Pie", which is not desired.

It just worries me that a simple API suddenly takes about 0.5 millisecond to execute and am wondering if other APIs are effected by this as well.
In the mean-time someone else found out that this is apperently caused by a SetThreadUILanguage call in D2010 which sets some flag in Windows Vista which makes GetTimeZoneInformation call tzres.dll on every call instead of only a few times in all the loops. On XP, only 0 is allowed, so there, LOCALE_INVARIANT is not used anyway. Note: this will not happen when you remove SysUtils from the above code.
