2. Welcome to DataFlex Reports! DataFlex Reports is a software tool for delivering timely, well organized reports and information to the people who need it.
Designed to be used by end-users, power-users and professional software developers alike, DataFlex Reports works with a wide variety of ODBC data sources including – but not limited to – Microsoft SQL Server, IBM DB2, Oracle, MySQL, Pervasive SQL, PostgreSQL, Microsoft Access, the DataFlex embedded database and more.
DataFlex Reports' Report Creation Wizard steps users through the entire process of creating a report from selecting data sources to grouping, filtering, summarizing and sorting information. The wizard displays the completed report in a visual, drag & drop WYSIWYG interface. Ready to view the results on-screen, print or make further formatting changes and enhancements. A full range of text formatting (fonts, bold, italics, justification, etc.) is available in DataFlex Reports along with a rich library of string, logical and math functions.
DataFlex Reports is developed in DataFlex, the state-of-art software development tool from Data Access Worldwide.
For DataFlex developers, DataFlex Reports offers both seamless integration with their DataFlex development environment and seamless integration of reports in Windows and Web applications. When DataFlex Reports is installed with DataFlex, a report integration wizard is automatically provided in the Studio.
For deployment, reports integrated in DataFlex Windows applications require only the installation of a single OCX. Distribution of integrated reports and the OCX is royalty-free with the Developer Edition of DataFlex Reports. To use integrated reports with a Web application requires a Web Deployment License.

3. Application Integration An Application Programming Interface (API) for DataFlex Studio is available. When DataFlex Reports is installed on a computer, if an appropriate version of DataFlex Studio is already present, this API can be optionally selected for automatic installation along with DataFlex Reports itself.
For the integration of DataFlex Reports in the DataFlex development environment a library workspace is installed and a new wizard becomes available in the DataFlex Studio performing the following steps:
• Selection of the report to be integrated in the current workspace and project. • Defining the criteria on which the end-user will be able to filter data when running the report. • Defining the sort order of the report. • Defining the Output Destinations that the end-user eventually can select. • Generating a Report View in the Studio. 3.1. Adding the DataFlex Reports Library to a Workspace In order to be able to use integrated reports in a DataFlex workspace the DataFlex Reports library must be added to that workspace.
Select the 'Maintain Libraries' option from the 'Tools' menu to add the DataFlex Reports library to the current workspace. Browse to the location of the DataFlex Reports library after clicking the 'Add Library' button in the Library Maintenance dialog that opens. In the library folder select the SWS file.
During the installation of DataFlex Reports one or more library versions could be installed. Depending on the installed DataFlex version a library can be installed or not.
Starting with DataFlex 18.2 the library maintenance dialog contains a 'DataFlex Reports Library' button. Clicking this button instead of 'Add Library' looks at usual locations (c:\libraries and .\libaries inside the DataFlex root folder). Working with an older version – or when the library is not installed in one of the default locations – requires browsing to the library folder that matches with the DataFlex product currently used and then select the SWS file from the folder.
Click the 'OK' button to connect the library to the workspace. A wizard will be started to guide through the attach library process.
When using DataFlex 18.0 or older; on the first wizard page (after the usual welcome page) a choice can be made to attempt to update the templates.xml file in the DataFlex Reports library. This feature is needed if the path to the integration wizard stored in the templates.xml file is incorrect.
The content of the second page of the wizard depends on the current DataFlex product. If version 17.1 or later is used the page contains options regarding web application integration. The contents of the library AppHtml\DataFlexReports folder need to be copied to the workspace if a web application is developed and integration is desired. This action can be skipped if a Windows application is being developed in the workspace. If a web application is developed the CSS files and a JavaScript file for previewing DataFlex Reports need to be loaded. The wizard looks for a file named index.html (default
Page 8 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
for DataFlex web applications) and offer to update this file. The wizard shows all available CSS themes available. Select the themes supported by the web application.
Starting with DataFlex 17.1 a folder named Reports as sibling of AppSrc and AppHtml will be the suggested folder for reports in a workspace. Reports used in a web application might need to store the output in a folder which is not directly accessible from the web browser. The suggested name is Cache to be created inside the Reports folder. The wizard can create these folders.
All wizard activities can be logged in a text file. Used the contents of this log file to resolve problems (if any). 3.2. Getting started with the Integration Wizard The library comes with a wizard that can write Windows or Web application components. The wizard operates different based on the current selected project (which is a web or a Windows type of application). First the Windows application integration is explained followed by Web application integration.
Page 9 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
3.2.1. Report integration for Windows applications To start the wizard, go to the File menu and choose the 'New' option, followed by the 'View / Report' option. The dialog to select from looks like:
For the explanation of the wizard that follows it is assumed that:
• The 'Order Entry' workspace is selected. • The DataFlex Reports library is added to that workspace. • A simple report, named CustomerList.dr , was created with DataFlex Reports in the Reports folder showing customer data. A report with this name is present in the WebOrder example folder and can be copied to the Reports folder of the 'Order Entry' workspace to bypass the requirement of creating one. • The Windows project ( Orders.src ) is selected in the workspace.
The first window explains the function of the wizard. Click 'Next' to proceed.
3.2.1.1. Existing or New Report On the next page offers connecting to an existing report or the creation of a new RDS (Runtime Data Source) based report. For now select 'Connect to an existing report'.
3.2.1.2. Select Report On the next page select the report named CustomerList.dr . The wizard looks in a folder Reports but the browse button can be used to select a report from another folder. Selecting a report from another folder has impact on the functionality of the wizard and the integration library. Selection list usage will not be made available for reports from a folder outside the workspace. If the report is based on tables of the DataFlex embedded database paths to the database or individual tables can be automatically corrected to the workspace paths.
Page 10 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
Select the checkbox "Auto correct DataFlex table paths to workspace paths" if this is desired. It should not be selected if report contains tables that are not present in the workspace without developer coding. In such a case it might be needed to write own code to connect report to data. If the data is retrieved from an ODBC or RDS data- source this option has no meaning. The preview button can be used to preview the report to discover if the correct report was selected. Running a report without selection criteria might take a while and previewing should not be chosen.
It is not possible to continue if the report was not created with the same version of the installed DataFlex Reports OCX. An error as shown here will be presented.
In such a case the report needs to be opened in the DataFlex Reports designer and saved to disk.
3.2.1.3. Selection Fields In the next wizard page – titled 'Selection Fields' – the columns that allow the end- user to specify selection criteria can be selected. The screenshot shows the columns 'Customer_Number' and 'Customer_City' as selected columns. If the end- user enters values in the input controls the data will be filtered on these values.
Page 11 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
The order of the input controls can be changed via right mouse click as shown in above image.
Note: The wizard will automatically create a connection to a selection list component if the workspace contains a data dictionary class for the table of the selected columns.
A drop-down (comboform) control will be created if the data dictionary contains a validation table for the selected columns.
If no data dictionary can be found or if the report uses ODBC or RDS data this feature cannot be offered and the developer would need to write own logic.
3.2.1.4. Report Filters The next wizard page depends on the report definition. If the report contains a filter (expert and/or filter function) the next wizard page(s) show the filters. Editing of the filter is not possible; selecting to keep or remove the filters can be done via the radios below the grid.
Keeping the filter definitions results in a report that filters the data on the predefined filter plus the values from the selection input controls.
3.2.1.5. Parameter Fields This wizard page appears if the report contains parameters a page will be shown with the parameters. One or more parameters can be selected for the creation of an input control.
A checkbox below the list of parameters makes it possible to ask the wizard to generate source code for the parameters that were not selected. Via source code these parameters can be given a value. The reference further in this guide handles the parameter usage.
The orderlist.dr report does not contain parameters
Page 12 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
3.2.1.6. Labels, Alignment and Anchors If there are input controls to be generated the wizard shows a labels and alignments page. On this page the generated label(s) for the input control(s) can be changed.
Use the ‘justification’ drop=down to indicate if the labels should be aligned left, right or above the control.
Use the ‘anchors’ drop- down to indicate what should happen with the control when the container resizes.
3.2.1.7. Filter Operator This wizard page – only available if fields for selection criteria have been chosen – allows to choose the filter operator and whether the wizard should create one of two input controls.
In most cases – especially if the 'from' selection is equal, less than, less than or equal but also for the other operators – only one input control for selection criteria is enough.
Accept the defaults or change the filter operator for each of the selection fields.
3.2.1.8. Sort Order After clicking 'Next' the wizard makes it possible to set the sort order of the data displayed in the details section of the report.
The wizard shows the record sort order defined in the report if any.
Page 13 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
With a right mouse click or via the tool-bar the sort direction (ascending or descending) can be selected per column. The floating menu also makes the sort order change- able.
With the checkboxes underneath the selected sort columns list it is possible to indicate that code needs to be written that allows the user to change the sort order and if this is a single sort order or a multi column sort order.
3.2.1.9. Functions The next step in the wizard depends again on the report.
If the report or one of the sub-reports contains user defined functions the wizard shows these functions.
Each of the functions can be inspected and selected for code generation.
The wizard can generated code for the functions that are designed to have a different value than entered during report creation can be changed via source code.
3.2.1.10. Preview Style The next wizard page makes it possible to decide what preview style to be used if 'preview report' is chosen.
If the report results should be sent to a printer or export the preview style cannot be chosen and running the report results in the output being sent to a printer or exported to a file.
The preview styles supported are:
Page 14 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
Modal dialog: Preview of the results need to be closed before further interaction with the application can be done.
MDI view: Preview style interface dynamically creates a view object (MDI child window) in the application's client area, displaying the report results.
Embedded in report view: Results and selection criteria needs to be placed in the same view. The wizard generates a report view with two tab- pages, one for the selection criteria and one for the results.
Toolpanel: This is a mix between a modal dialog and an MDI view. The results window pops out (comparable to a modal dialog) of the program but navigation to other parts of the application are possible (like an MDI view).
The checkbox for prompt list support can be ticked if creation of selection criteria controls is selected earlier in the wizard process and prompt list support can be made available by the wizard. The DataFlex framework supports two kinds of selection lists; the wizard cannot know what selection lists are currently in use or will be used in the (near) future. Knowledge of the workspace contents is necessary to make a correct decision.
3.2.1.11. Project Options The next step in the process concerns the embedding of bitmaps and icons in the executable.
The library contains a number of images used in a toolbar and in dialogs. The images need to be distributed with the application as external files or embedded in the compiled project. The DataFlex compiler embeds the images listed in the
Page 15 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
A workspace may contain several projects. Not all projects might need a connection to DataFlex Reports. Select the projects for which the library bitmaps and icons need to be added to a project's CFG file. Make sure the project's CFG file(s) is/are writeable.
3.2.1.12. Names The next wizard page requires specification of the component object, the file name and description to be used for the menu item creation.
If the object name does not start with an 'o' the wizard suggests to change the name.
The wizard creates names based on the name of the chosen report. The name shown in the picture contains CustomerList as the report filename was CustomerList.dr . The object name needs be unique within the current project. The wizard cannot check if the name is unique or not. The wizard will generate a ReportView based object that will be used to address the module.
3.2.1.13. Language & ODBC data-source The next step in the wizard is valid for Windows or Web projects with DataFlex Reports integration. By choosing a language the print engine translates language items such as ‘Page N of M’ into the chosen language.
If the report is based on an ODBC data-source the second option can be selected which generates code in the report object in which a change in the data- source can be programmed.
3.2.1.14. Component Finished After all your choices have been made we can finish the creation of the ReportView module by clicking the 'Finish' button. The wizard will close and generates a Report View component.
Page 16 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
The generated Report View is now available in DataFlex Studio.
Notice the prompt button for the selection of 'Customer Number'. The selectionlist is available because the data dictionary class for the customer table in this workspace defines a selection list.
The controls are not data-aware, the view does not contain data dictionary objects, browsing for a customer is not possible if not using the selection list.
Once the Report View is created in DataFlex Studio, everything is based on source-code. Double-clicking on the View (or toggling to source view by pressing the F7-key) shows the source-code.
The layout or position of any visual object in the ReportView component can be altered within the DataFlex Studio designer.
It is worth taking a closer look at procedures – e.g. 'OnInitializeReport' & 'SetFilters' – created by the wizard. For example the 'SetFilters' method which defines the report filter based on the user input.
Simply pressing the F5 key will compile and run the application. The end-user can now easily make selections, set the sort order and then preview, print or export the report results.
The report view does not need to have input controls for selections, sort order and destination and can be condensed as only having a print and cancel button. In this case the report contains everything that is needed to integrate or all options are fully coded in the report or ReportView object. Copying the report object and a print button to a view like the order view to only print the current order is fully supported. 3.2.2. Report integration for DrillDown Mobile/Touch Web applications To start the wizard, go to the File menu and choose the 'New' option followed by the 'Web Object' option. The dialog to select from looks like:
Page 17 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
For the explanation of the wizard that follows it is assumed that:
• The 'WebOrderMobile' workspace is selected. • The DataFlex Reports library is added to that workspace. • A simple report, named CustomerList.dr , was created with DataFlex Reports in the Reports folder showing customer data. A report with this name is present. • The Web project ( WebApp.src ) is selected in the workspace.
The first window explains the function of the wizard. Click 'Next' to proceed.
3.2.2.1. Existing or New Report On the next page offers connecting to an existing report or the creation of a new RDS (Runtime Data Source) based report. For now select 'Connect to an existing report'
3.2.2.2. Select Report On the next page select the report named CustomerList.dr . The wizard looks in a folder Reports but the browse button can be used to select a report from another folder. Selecting a report from another folder has impact on the functionality of the wizard and the integration library. If the report is based on tables of the DataFlex embedded database paths to the database or individual tables can be automatically corrected to the workspace paths. Select the checkbox "Auto correct DataFlex table paths to workspace paths" if this is desired. It should not be selected if report contains tables that are not present in the workspace without developer coding. In such a case it might be needed to write own code to connect report to data. If the data is retrieved from an ODBC or RDS data- source this option has no meaning. The preview button can be used to preview the report to discover

if the correct report was selected. Running a report without selection criteria might take a while and previewing should not be chosen.
It is not possible to continue if the report was not created with the same version of the installed DataFlex Reports OCX. An error as shown here will be presented.
In such a case the report needs to be opened in the DataFlex Reports designer and saved to disk.
3.2.2.3. Webview Style In the next wizard page select "Drilldown – Mobile/Touch" for the webview style.
Based on selecting the style the wizard generates different source code.
While combining "Desktop" and "Drilldown – Mobile/Touch" webviews is possible within one project it is easier, better to select the component style that matches the application style.
3.2.2.4. Selection Criteria The next step in this integration example is about the creation of selection criteria input controls.
Selection criteria can be hard coded or a user can be allowed to enter the criteria values.
As shown; select the 'City' and 'State' columns.
The wizard generates input controls to enter these filter values.
The order of the input controls can be changed via right mouse click as shown in above image.

3.2.2.5. Report Filters The next wizard page depends on the report definition. If the report contains a filter (expert and/or filter function) the next wizard page(s) show the filters. Editing of the filter is not possible; selecting to keep or remove the filters can be done via the radios below the grid.
The screenshot shows a filter on the customer_number column and all rows not equal to the value of 10 are valid.
Keeping the filter definitions results in a report that filters the data on the predefined filter plus the values from the selection input controls.
3.2.2.6. Parameters If the report contains parameters a page will be shown with the parameters. One or more parameters can be selected for the creation of an input control.
A checkbox below the list of parameters make it possible to ask the wizard to generate source code for the parameters that were not selected.
Via source code these parameters can be given a value.
The reference further in this guide handles the parameter usage.
The customerlist.dr report does not contain parameters.
An input control will be generated for each of the selection and/or parameter fields.

3.2.2.7. Labels, Justification and Position The generated label for the input control can be changed in the labels and alignment wizard page. The page is only available if there are selection or parameter input controls to be created.
The 'Show' checkbox for each label allows to generate the label setting but hide the appearance.
Make your choice for the label justification mode and the label position from their drop-downs at the bottom of the page.
3.2.2.8. Filter Operator This wizard page – only available if fields for selection criteria have been chosen – allows to choose the filter operator and whether the wizard should create one of two input controls.
In most cases – especially if the 'from' selection is equal, less than, less than or equal but also for the other operators – only one input control for selection criteria is enough.
Accept the defaults or change the filter operator for each of the selection fields.

3.2.2.9. Select & Zoom Views A typical DrillDown – Mobile/Touch application usually contains select and zoom webviews.
Based on the number of selection criteria the wizard makes it possible to connect one or more selection criteria to existing 'Select' views or to create a new 'Select' view.
The connect-to or creation of a select view is present to help the user creating a useful filter value.
The screenshot to the right shows the 'to' column is unavailable. This is because in the previous wizard page only a 'from' selection criteria was chosen.
Clicking the prompt button in the 'From' column brings a Windows file selector dialog. Select the webview component that can be used to get the selection criteria from.
If there was only one selection field chosen the wizard page would look like:
The first option lets the wizard create a cWebList control. Use this if there is not a select view page available yet or if this page should be different. Enhancements to the list can be made after the select view page is created by the wizard.
The second option makes it possible to connect to an existing select view.
The third option tells the wizard to create an input control without connections to a select view page.
The created page will be very light as it will only contain one input control. Futher enhancement of the page is suggested.

3.2.2.10. Sort Order After clicking 'Next' the wizard makes it possible to set the sort order of the data displayed in the details section of the report.
The wizard shows the record sort order defined in the report if any.
With a right mouse click the sort direction (ascending or descending) can be selected per column. The floating menu also makes the sort order change-able.
With the checkboxes underneath the selected sort columns list it is possible to indicate that code needs to be written that allows the user to change the sort order and if this is a single sort order or a multi column sort order.
3.2.2.11. Functions The next step in the wizard depends again on the report.
If the report or one of the sub-reports contains user defined functions the wizard shows these functions.
Each of the functions can be inspected and selected for code generation.
Functions that are designed to have a different value than entered during report creation can be changed via source code.
The customerlist.dr report contains one function that should not be changed at integration level.
Page 23 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
3.2.2.12. Report View Options Next step in the integration process is the selection of the output representation. DataFlex Reports can output to PDF, HTML, four image formats, XLS/XLSX, RTF (Word) and CSV. All formats are supported at integration level. HTML is the default output option for DrillDown – Mobile/Touch style applications.
With each of the output options different destination options become available. For example with HTML the output can be shown in a HTML previewer control on a 'Results' page or in the 'Select' page. The wizard generates two web components in case of the 'HTML Viewer Results Page' page destination option.
A web report view contains a column layout. The value for the number of columns in the web view can be entered. Default is 12 and is usually ok. The value can be changed later in the DataFlex Studio.
Optionally a view width can be entered. No value means full width of the browser.
3.2.2.13. Names When the user can enter selection criteria, a sort order or parameter values the wizard creates two web components. A select and a results page.
If there is no UI only one component will be created.
In the next wizard page(s) the object name of the web component, the name of the source file on disk and a description can be entered. The default values shown are based on the name of the selected and opened report.
A confirmation question pops up if there is already a file with the entered name.
The name of the objects needs to be unique in the web project. The wizard cannot check if the names are unique or not.

Printed in bold is shown that this report view will be added to WebApp.src which is a confirmation that the correct project type was chosen.
3.2.2.14. Language & ODBC data-source In the next step of the wizard it is possible to choose if an instruction to set a language should be generated for translation of language items such as "Page N of M" into the chosen language.
If the report is based on an ODBC data-source the the 'Generate code for..' checkbox can be selected. This generates a method in the report object in which a change in the data-source can be programmed.
3.2.2.15. Component Finished Next step in the process is finishing the wizard and the generation of the source code. The generated code will be loaded in the DataFlex Studio and the newly generated select component will be added to the webapp project and the 'View" pull-down.
Review the generated code and make visual enhancements like re-organizing the input controls.
Take a look at Studio's todolist panel to resolve the ToDo items created by the integration wizard.
The above screenshot shows the selection criteria for the customerlist report in the browser. Pressing the 'Run Report' button or using the 'Run Report' option from the menu on the right results in:

3.3. DataFlex Reports Application Programming Interface Any report built by DataFlex Reports stores its definition in the file with the .DR extension. The definition is read by the DataFlex Reports Runtime, which is actually an OCX. The OCX (named DataFlex Reports 2016 Developer Edition API.ocx ) can do more than just represent a report. The runtime OCX contains several functions that are made available to programmers.
The interface functions can be grouped in sections for report, preview, data source, filter, function, columns, export and progress.

3.4. Report integration classes The DataFlex Reports integration library contains two major classes for report integration in an application. The cDRReport class can be used in all kind of applications while the cWebDRReport class – a sub-class of cDRReport – is designed for web application integration. 3.4.1. cDRReport class The cDRReport class is a subclass of the cDRAPI ActiveX wrapper class, which should not be used for object instantiation. For this the cDRAPI class is marked as abstract and thus the cDRReport class should be used. The interface in the cDRReport class protects against writing incorrect code instructions.
For printer selection and controlling the PrintReport method you use an object of the cPrintDialog class, which is a class that we supply with the DataFlex Reports library.
3.4.1.1. How to use the cDRReport class Running reports side-by-side can be done by creating multiple instances of the cDRReport class at the same time, if the preview output is not sent to a modal dialog. Running ReportA and then ReportB can be done using one instance of the cDRReport class.
The most important property of the cDRReport object is the psReportName property which needs to be set to the filename of the report (e.g. CustomerList.dr ). Without this the engine won't know what report to execute. The property can be set in a static or dynamic way. The report file name in psReportName may contain a path. Normally no path is given if the report resides in a folder of the application's workspace. If a path is not specified an attempt is made to locate the report by the OpenReport function. The following sequence is used to locate the report, until the report file is found or no report file by the specified name is found.
1. The folder location can be stored in a property named psReportPath . Even if this property is not empty the report file may not be there. 2. Only when compiling and running with DataFlex 17.1 or later, the Reports folder is searched for the report. The location of the Reports folder is returned by a function named ReportsFolder . The default is a folder named Reports in the root of the workspace. 3. The folders of the application's data paths are enumerated to locate the report. The application's data paths are stored in the DataPath setting in the workspace file (e.g config.ws ). This value is programmatically accessible via the psDataPath property of the workspace object in the application.
Note that when the project does not have an application object (instance of cApplication ) – this is very rare – there is no workspace object, there are no data paths, there is no Reports folder. The path to the report filename needs to be part of the file in the psReportname or the psReportPath property must be set to the location of the reports.
Before report settings can be queried or altered the report must be opened using the OpenReport function. The OpenReport function returns the report ID, which is a GUID (Globally Unique Identifier). If the report cannot be opened the return value will be an empty string.
If the report uses tables from the DataFlex embedded database (or tables from an external database described by intermediate (INT) files) the class will attempt to automatically locate the database and tables and adjust paths in the report at runtime. This change of table location is not persistent. If the workspace contains multiple tables with the same name or when it uses a different technique to locate and open tables it is better to set the pbAutoLocateDFFiles property to false.
Page 30 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
If a manual change of the location of the database and tables is desired the properties psDatabaseName , DatabaseType , psDatabaseConnection , and psTableSchema should be used. psDatabaseName contains the name of the filelist or the first table in an environment using the embedded DataFlex database, DatabaseType indicates whether it is an embedded DataFlex database that is used or an ODBC datasource, psDatabaseConnection contains the DataFlex DF_OPEN_PATH or the DSN that gives access to the ODBC datasource, and psTableSchema contains the path to a table when the embedded DataFlex database is used and tables are not opened via the filelist or the table schema if available in case of an ODBC datasource.
The property psTableName returns the name of the N-th table in the report. The function TableCount returns the number of tables present in the report. If the report is based on an ODBC or Stored Procedure datasource it is possible to let the integration wizard generate code to assist in changing the DSN for the report, look for a method called ChangeODBCDataSource .
An opened report can be displayed; its data can be exported or printed to a print device. Sending the RunReport message to the report will open the report and then output the report to screen, printer or file. The method of output is controlled by the property peOutputDestination which can have the values PRINT_TO_WINDOW , PRINT_TO_PRINTER , PRINT_TO_PRINTER_NO_DIALOG or PRINT_TO_FILE . The report remains open after output. If the report was not opened before sending RunReport to the report object results in an attempt to open the report by calling the OpenReport method. As mentioned above the OpenReport message can be send to only open the report and change or query some settings with or without creating output.
During OpenReport it is possible to show a status panel to the end-user. This is controlled by the property pbShowStatusPanel in combination with the property phoStatusPanel that holds the object id of the statuspanel. Both properties need to be set by the developer and are false and 0 by default.
If the output of the report is expected to take some time it would be good to display information about reading and processing data to the end-user. This can be done by implementing the event OnProgressRecordsRead and displaying the number of records read and/or the event OnProgressFormatPage to display how many pages have been formatted out of the total number of pages. The integration wizard already writes the code for these events in the cDRReport object.
Instead of running the report and depending on the property peOutputDestination it is possible to open the report (with the OpenReport function) and then either send the message DisplayReport , ExportReport or PrintReport . The report must be opened before one of these three messages can be sent.
When the report executes, the DataFlex application continues to respond to mouse clicks, function keys etc. since the report data reading and formatting process is done in an ActiveX module.
For exporting or printing the report it is not necessary for the ActiveX to be displayed in a DataFlex container object (e.g. a (db)View).
After opening the report, record filters can be set in two ways. One way is via the psFilterFunction property. The syntax of the VB Like function code that needs to be written for this function can be checked via the function TestFilterFunction . It is not a requirement though. The second way is via the methods AddFilter, RemoveFilter , RemoveAllFilters . Existing filters can be altered via the method FilterCount in combination with the properties psFilterField , peFilterOperator and psFilterValue .
The class also gives access to any of the stored functions in the report. The number of functions can be queried via the method FunctionCount . Each function can be addressed via the methods psFunctionName and psFunction . If the function name is known, the FunctionIdByName returns the function ID. It is not possible to add new functions to the report, only to change existing functions.
Page 31 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
A report may contain one or more sub-report(s). A sub-report may contain one or more other sub- report(s). The number of nested sub-reports is not limited but using sub-reports has an impact on the execution speed. The number of sub-reports in a report can be queried via the method SubReportCount and their IDs can be retrieved via the function SubReportID . The sub-report can and should be further accessed in its entirety as if it was a report on its own. If the pbAutoLocateDFFiles is set to false (or when an ODBC data-source is used) the data-sources in the sub-report(s) needs to be adjusted manually (if needed). Each method that requires the passing of a report id can have the main report id or the id of a sub-report passed.
For exporting the report a choice can be made between export to image, to CSV (Comma Separated Values), to XLS (Excel), to RTF (Word), to Image, to HTML or to PDF (Portable Document Format). In all six options a variable with the appropriate settings for the export format needs to be passed. For this use the write only properties pImageExportOptions , pCSVExportOptions , pXLSExportOptions , pHTMLExportOptions, pRTFExportOptions or pPDFExportOptions . The DataFlex Reports print engine may crash if these properties are not set with appropriate information prior to the export.
When the report is displayed in the viewer and page navigation controls are desired, documentation about the methods PreviewFirstPage , PreviewLastPage , PreviewNextPage , PreviewPreviousPage and the property piPreviewCurrentPage should be read.
Any errors that are generated during any of the class methods, or which are sent to the object by the viewer OCX, are automatically handled by the cDRReport object itself. As with the usual global DataFlex error handler the method Error_Report is used. This method first determines if it is handling errors already and if so skips the new error to avoid recursion. The next step in the process is calling the OnError event which could be used to log error information into a log-file, send an e-mail etc. When the property pbDisplayError is set to true (the default is True) the error is passed to the standard error handler object. In the OnError event the pbDisplayError could be set to false to avoid having the standard DataFlex error handler picking up the error. If the property pbCancelIfError is true (the default is True) the pbCanceled property will be set to true to avoid follow-up errors in other report methods.
Closing the report can be done with the CloseReport message. Don't do this while the report is still needed (e.g. in viewing pages). When a different report is opened the old report will automatically be closed. When the ActiveX object is deactivated (the dialog to where it was paged is deactivated or during destroy) the currently opened report will be closed as well.
While using the DisplayReport message (or RunReport with the peOutputDestination set to PRINT_TO_WINDOW , which is the default) the report object should have a size big enough to display the report, or the preview window handle has to be set to an object big enough to display the report results.
Report errors and special fields in the report can displayed/printed in a specific language. Use the piReportLanguage property for specifying the language. The text strings for this language support are read from a database named language.db which is delivered with DataFlex Reports. A set of popular languages are delivered with DataFlex Reports.
If the data is sorted locally, the sort order is configurable when using ODBC and is standard for DataFlex data.
Reports can be based on runtime data. To pass data the application has to build a two dimensional variant array that matches the data source defined in the report and fill it with the data to be displayed, exported or printed. The variant array is passed to the report via the TableData method.
Page 32 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu
A report can be based on a stored procedure that delivers the data to the report. The optional parameters of a stored procedure can be accessed via the methods ParameterCount , ParameterName , ParameterType and the property psParameterValue . These same methods and the property can be used for parameters defined in the report.
Preview results can be shown via the ActiveX object on a (report)view, in a modal dialog, an MDI view or a tool-panel. The pePreviewStyle property controls the display "channel".
Many functions and properties take a report ID as first argument. This report ID is the GUID (string representation) returned by the OpenReport function. The value can be passed as an empty string (or C_USEMAINDRREPORTID ) if the main report is should be used. The function or property retrieves the psReportID property value for the report ID.
In the next paragraphs detailed information about the properties, the methods and the events of the cDRReport class can be found.
3.4.1.2. Translation All messages and constants used in the cDRReport class and dialogs are available in a number of languages. For each language the file that contains the translations is named DRLanguage
Requests for additional languages can be send to Data Access Europe by e-mail ([email protected]).
The integration wizard uses dynamic translation following the language choice in the DataFlex Reports designer. The translation strings are read from a database named language.db located in the programs folder where the integration wizard is installed. When the translation cannot be found the default English translation is used. Note that both the DataFlex Reports designer and the integration wizard use a database named language.db but that the contents differ. The language.db for the designer does not work for integration and vice-versa.
3.4.1.3. Properties The cDRReport class defines the following properties
3.4.1.3.1. pbAllowMaximizeView Type: Boolean Default: False Arguments: - Description: This property is used by the cDRPreview class to set the Maximize_Icon of the dynamically created view.
Page 33 of 183 Business Software for a Changing World TM z Data Access Europe B.V. / Lansinkesweg 4 / 7553 AEHengelo, The Netherlands +31742555609 [email protected] www.dataaccess.eu

3.4.1.3.5. pCSVExportOptions Type: drCSVExportOptions structure, see 3.8.1 Default: See 3.8.1 Arguments: - Description: This write-only property needs to be set before export to CSV (ExportReport ) can be done. The property needs to be set to a value of the drCSVExportOptions data-type.
This property cannot be set before the report OCX object is initialized and a report is opened ( OpenReport ).
The function DefaultCSVExportOptions can be called to initialize the drCSVExportOptions variable.

Type: Function
When the property psReportId contains a value the class attempts to close a report – via CloseReport – with that value as ID.
OpenReport can be used directly by your code and it will also be called when RunReport is executed. When OpenReport is successful the report is opened and the return value is the report id, which is also automatically stored in the property psReportId .
The OnInitializeReport event is called during OpenReport . This event can be used to set additional properties like psFilterFunction or psFunction .
In a windows application; If pbShowStatusPanel is true and phoStatusPanel contains an object id, a popup message is sent to the status panel object. This statuspanel can be used this to inform the user about to the report's loading progress.
The property pbCanceled can be used to abort the loading or running of the report.

3.5. Templates The DataFlex Reports library contains one component template which can be used to make a reportview component in the DataFlex Studio. With this template you can build the same kind of component as with the wizard when you select "Embedded in Report View". The difference is that you need to do it all "by hand". The created reportview contains a commandbar object with toolbar, a cDRReport object and two buttons. 3.5.1. phoReport property The reportview object defines a property named phoReport in which the object id of the cDRReport object is stored. This property is used by the commandbar button objects such as oNextPage. Using this property makes it is easier to change the name of the cDRReport object without further references that need to be changed.
While you can change the assignment for this property in the code for the cDRReport object this is neither necessary nor recommended. The code written by the template contains:
Object oReport is a cDRReport Set Size to 215 397 Set Location to 18 7 Set phoReport to Self End_Object
3.5.2. oCommandBars object A means of browsing through pages of the report preview is desirable. One of the ways to achieve this is by adding a CodeJock class based toolbar inside the reportview. The toolbar is in fact a commandbar and thus you see an oCommandBars object. 3.5.3. oDRToolbar object As standard this object contains 9 button objects to control the previewed report. All the button objects are instantiated from a class that derives from the cDRMenuItem class. The following toolbar buttons are created.
3.5.3.1. First Page This button will, when clicked, send PreviewFirstPage to the report object retrieved by the ReportObject function call. The picture displayed is FirstPage.bmp and it is advised to add this to the embedded images via the project properties.
3.5.3.2. Previous Page This button will, when clicked, send PreviewPreviousPage to the report object retrieved by the ReportObject function call. The picture displayed is PreviousPage.bmp and it is advised to add this to the embedded images via the project properties.
3.5.3.3. Current Page This "button" is an edit control with spin functionality which displays the current page of the report preview and allows the operator to enter a different page number. The piPreviewCurrentPage will be set to the entered page number when the operator presses the Enter key or presses the up/down spin buttons. The report object is retrieved via the ReportObject function call.
3.5.3.4. Next Page This button will, when clicked, send PreviewNextPage to the report object retrieved by the ReportObject function call. The picture displayed is NextPage.bmp and it is advised to add this to the embedded images via the project properties.

3.5.3.5. Last Page This button will, when clicked, send PreviewLastPage to the report object retrieved by the ReportObject function call. The picture displayed is LastPage.bmp and it is advised to add this to the embedded images via the project properties.
3.5.3.6. Refresh Report Data This button will when clicked send RefreshReport to the report object retrieved by the ReportObject function call. The picture displayed is Refresh.ico and it is advised to add this to the embedded images via the project properties.
3.5.3.7. Print Report Data This button will, when clicked, send PrintReport to the report object retrieved by the ReportObject function call. The picture displayed is Print.bmp and it is advised to add this to the embedded images via the project properties.
3.5.3.8. Current Zoom Factor This "button" is an edit control with a drop down option so that you can enter a zoom factor for the report freehand or choose from a predefined set of zoom factors. The control will also show the current zoom factor of the previewed report. The report object to be addressed is retrieved via the ReportObject function call. The zoom factor must be between 25% and 500%.
3.5.3.9. Export Report Data This button will, when clicked, send ExportReport to a report options dialog passing the report object retrieved by the ReportObject function call. The report options dialog is specified in the property phoExportOptionsDialog defined for the class of this button. The picture displayed is Export.bmp and it is advised to add this to the embedded images via the project properties. 3.5.4. oReport object This is the DataFlex Reports proxy object that lets your DataFlex program access the report, alter filters, sorting, etc and then run the report. The report object by default stores its object id in the phoReport property of the ReportView object.
3.5.4.1. Events All events defined for the cDRReport class are supported and can also be found in the events tab-page of the object properties panel in the DataFlex Studio.
The template sets up 3 events:
• OnInitializeReport • OnPageChanged • OnZoomChanged
The OnPageChanged and OnZoomChanged events communicate with a toolbar "button" object and it is quite normal to configure the report execution; therefore OnInitializeReport is added to the object. 3.5.5. Button Objects Finally the template adds two buttons to the ReportView object. The button named oRunButton sends RunReport to the report object via the object id in phoReport . The button named oCancelButton attempts to close the component.

To allow the user to easily execute the messages that the buttons send, two On_Key statements are added; these send the KeyAction messages to the appropriate button. The key combinations are Alt+C and Alt+R.
3.5.6. Other Key Mappings
The template also defines On_Key statements for browsing to the first (Ctrl+Home), next (PageDown), previous (PageUp) & last page (Ctrl+End) of the report.

3.6. Printing It is possible to let the user select a printer via the print dialog or you can specify a printer or you can print to the default printer. The cDRReport class contains two methods to print the report. This paragraph explains you how to print a report. 3.6.1. User Selects a Printer If you want to have the end-user select a printer you can pass a zero as argument to the PrintReport message and not set the psPrinterName property. The system uses the cPrintDialog object created with each cDRReport object. The object handle to the cPrintDialog object is stored in phoPrintDialog.
Send PrintReport of oReport 0
3.6.2. Default Printer If you want to print to the default printer you can send the message PrintToDefaultPrinter to the report object. This method will retrieve the Windows default printer by using the cPrintDialog object whose ID is stored in phoPrintDialog . The gathered information will be passed to the PrintReport method.
Send PrintToDefaultPrinter of oReport
Or:
Set peOutputDestination of oReport to PRINT_TO_PRINTER_NO_DIALOG Send OutputReport of oReport
3.6.3. Printing To a Specific Printer It is possible to print to a specific printer without the printer selection dialog appearing. For this you set the psPrinterName property of the report object and send the message PrintReport passing a zero as message argument.
Set psPrinterName of oReport to "OKI 1234" Set peOutputDestination of oReport to PRINT_TO_PRINTER Set phPrintDlg of oReport to 0 Send OutputReport of oReport
Alternative
Set psPrinterName of oReport to "OKI 1234" Send PrintReport of oReport 0
The name of the printer must be a valid name and its driver properties must be accessible else the printer selection dialog appears.

4. Deploying the DataFlex Reports Developer Edition Runtime The DataFlex Reports Runtime can be distributed royalty-free with your reports and DataFlex Windows application only if you have a legitimately licensed DataFlex Reports Developer Edition. For Web applications a Web Deployment license (per server) is required.
The target platform for deployment requires as minimum a DataFlex Client Engine based system, but a development version of DataFlex is certainly allowed.
The Software License Agreement explains these distribution entitlements in detail. If you have any questions about licensing, send an email to [email protected].
The DataFlex Reports Developer Edition Workstation Runtime consists of the following components required to execute Reports:
Module Description Version DataFlex Reports 2016 The DataFlex Reports API 5.0 Developer Edition API.ocx Df_collate.cfg The collating sequence used for DataFlex embedded data - sources. Language.db A SQLite database with translation text strings. If the file is - missing, the built-in default language is used. The file needs to be in the same folder as the DataFlex Reports OCX. DR.db A SQLite database in which the repositories, label definitions - and imported ELF functions are stored. The file needs to be placed at a location to which you have write access. The file is located in the following ways: • Sub folder of ProgramData; in Windows Vista or later the exact folder is C:\ProgramData\Data Access Worldwide\DataFlex Reports\5.0\Data • Directory of the DataFlex Reports OCX The Runtime can best be deployed in the same directory as your DataFlex application, which can be either on the licensed personal computer or on a network server. Typically, this is the \Programs directory of the deployed workspace.
Register the DataFlex Reports 2016 Developer Edition API.ocx on the deployment computer(s). Use the Windows RegSvr32 tool for this. On Windows Vista and later you should run RegSvr32 with "run as administrator".
Note: The internal structure of the dr.db file changed in version 5. Using a dr.db of an older version causes label reports to fail.
