Net Microsoft Visual Basic . NET • Microsoft Visual Basic is a programming environment used to create graphical user interface (GUI) applications for the Microsoft Windows family of operating systems. • It usually ships either by itself or as part of Microsoft Visual Studio. 5 Microsoft Visual Basic . NET • Microsoft's Visual Studio includes several different programming languages: • Visual Basic, • Visual C# (C sharp), • Visual C++ (cee-plus-plus), • Visual F# (F sharp), • JScript and • Web Development (called ASP.NET). • It also includes the .NET 4 Framework upon which these languages operate. 6 Microsoft Visual Basic . NET • Visual Basic is an object-oriented programming language. • You work with objects in building an application. • Examples: Form objects, Button objects, TextBox objects, Label objects, ListBox objects, PictureBox objects, and more. 7 Microsoft Visual Basic . NET • There are three primary steps involved in building a Visual Basic application: 1. Draw the user interface 2. Assign properties to controls 3. Attach code to controls 8 Launching Visual Studio Launching Visual Studio 10 Start A New Project Start A New Project 12 Screen Elements Screen Elements Solution Explorer Window: Displays Toolbars filenames for files that comprise a project. Form Designer (Document Window) Toolbox: Contains controls that are used to build forms. Properties Window: Displays properties of the currently selected object. Error List Window 14 Toolbox Quick Search Tool Description Button Raises an event when the user clicks it. CheckBox Enables the user to select or clear the associated option. ComboBox Displays an editable text with a dropdown list of permitted values. Label Provides runtime information or descriptive text for a control. ListBox Displays a list from which the user can select items. PictureBox Displays an image. RadioButton Enables the user to select a single option from a group of choices when paired with other radio buttons. TextBox Is used to display information entered at design time, by a user at run-time, or assigned within code. The displayed text may be edited. GroupBox Displays a frame around a group of controls with an optional caption. 15 Adding Controls Using Toolbox Activity (1) Adding Controls using Toolbox Create a form that has 3 textboxes and 3 labels Double Click/Drag and Drop 17 Activity (1) Adding Controls using Toolbox Create a form that has 3 textboxes and 3 labels Double Click/Drag and Drop √ 18 Controls Properties Controls Properties • Controls you added to the form (textboxes and labels), and the form itself, are called control objects. • In VB.NET, you can change the appearance properties of a control (text, Text alignment, Font, color, etc.) through the Properties Window (menu). • Example: If your television were a control, it too would have properties: On/Off button property, color property, volume property, and so on. 20 Activity (2) Controls Properties Change the properties of the form you’ve created earlier to be look like this: 21 Activity (2) Controls Properties (1) Change the value of the text property of a form Click on the Form Click inside the area next to "Text", and delete the word “Form1” When "Form1" has been deleted, type the words “My First Form” √ 22 Activity (2) Controls Properties (2) Change the value of the text properties of the 3 labels Click inside the area next to "Text", and delete the word “Label1" When “Label1" has been deleted, type the Click on the label1 words “First Name" √ Do the same for label 2 and label 3 23 Activity (2) Controls Properties (3) Change the font size of the labels Click on the label1 In the properties menu, select the Font property and click on the … Button 24 Activity (2) Controls Properties (3) Change the font size of the labels √ Change the following: Font: MMa Century Font Style: Bold Size: 12 Do the same for label 2 and label 3 25 Activity (2) Controls Properties (4) Change the color property of the form Click on the Form 26 Activity (3) Create a Pizza Order to be look like this: 27 Activity (3) (1) Add Controls (GroupBox, RadioButton, CheckBox, PictureBox, ComboBox, Button) GroupBox [RadioButton] PictureBox GroupBox [Check Box] Combo Box Button Radio Button 28 Activity (3) (2) Set Form Properties Form: Color Property [Choose any Color] Form: Text [Pizza Order Form] 29 Activity (3) (3) Set GroupBox and RadioButton Properties Group Box: Text [Size] Radio Button: Text [Small, Medium or Large] Radio Button: Text [Eat in or Eat out] 30 Activity (3) (4) Set GroupBox and CheckBox Properties GroupBox : Text [Toppings] CheckBox : Text [Black Olives] 31 Activity (3) (5) Set Picture Properties To add a picture: (1) Click on the picture box. (2) In the properties menu, select image property and click on … Button 32 Activity (3) (5) Set Picture Properties 33 Activity (3) (5) Set Picture Properties 34 To add a items to a combo Box: (1) Click on the combo box. Activity (3) (2) In the properties menu, select Items property and click on … Button. (6) Set ComboBox Properties (3) Type Items each on a separate line. ComboBox :Text [Crust Type] ComboBox: Items: Thin Stuffed Crust Deep Pan 35 Activity (3) (6) Set ComboBox Properties √ 36 Activity (3) (7) Set Button Properties Button1: Text [Order] Button2: Text [Close] 37 Debugging A Program Debugging A Program • Debugging (Running) is the process of locating and fixing bugs (errors) in computer program code. You can start debugging mode by: (1) Clicking on the Green Arrow (2) Clicking on Debug from menu bar > Start Debugging . (3) Pressing F5 on your keyboard . 39 Saving A Program Saving A Program 41 Saving A Program Click here To change the Location of the File 42 Create Variables in VB.NET VB .NET Variables • A variable is a storage area of the computer's memory. • Variable Declaration Syntax : Dim VariableName As DataType VariableName: the variable we declare for hold the values DataType: the type of data that the variable can hold. • You can declare multiple variables of the same or different type in the same line, as follows: Dim Qty As Integer, Amount As Decimal, CardNum As String Dim Length, Width, Height As Integer, Volume, Area As Double 44 VB .NET Variables • Visual Basic recognizes the following five categories of variables: • Numeric: store numbers. • Integer: store whole numbers. • Decimal: useful when we want a precise number of decimal places. • Single: floating-point numbers with limited precision. • Double: floating-point numbers with extreme precision. • String: store text. • Boolean: store True or False data. • Date: store date (year, month, day, time) data. • Object: store any type of data. 45 Activity (1) Write a programme to add two numbers together and display the answer in a msgbox. √ 46 Activity (2) Write a programme to add two numbers together and display the answer in a textbox. √ 47 Activity (3) Write a programme to add ANY two numbers and display the answer in a textbox. √ 48 Activity (4) Create the following form that contains two labels for variables (a) and (b) and two textboxes for displaying the values of the variables. • The Single and Double data type names come from single-precision and double- precision numbers. • Double-precision numbers are stored internally with greater accuracy than single precision numbers. • In fact, computers must store values in a fixed number of bytes, so the accuracy will be lost. √ 49 Activity (5) Create a third textbox to display the difference (a-b) √ 50 Activity (6) If the information we want to store in our variables is a First Name and a Last Name. • A string is a sequence of characters, and you use double quotes to mark its beginning and end. • Concatenation means linking something together in a chain or series. If you have two strings that you join together, one after the other, you say they are concatenated. You can think of concatenation as addition for strings. • The ampersand symbol ( & ) is used to join strings together. √ 51 Activity (7) If the information we want to store in our variables is a First Name and a Last Name. As you can see, the two words are actually joined as one. We can add a bit of space between the two words by using another ampersand. √ 52 Activity (8) If the information we want to store in our variables is a First Name and a Last Name. √ 53 Notes on Coding (Text) VS. (Name) Property 55 Code Comments • You can write comments to yourself or any other programmer to indicate what a code sentence is for by adding the symbol ( ‘ ) before the comment you want to add. 56 Message Boxes • There are two ways to display output in a message box: Msgbox (Result) and Message.Show (Result, “Solution”). 57 Message Boxes 58 Visual Basic Operators and Functions Homework Solve Activity One and Two (Page 30-35). Decision Statements Activity (1) If… Then Statements Create a simple program to display the message “Number is indeed 27!” when the variable called Number is 27. √ 61 Activity (2) If… Then Statements Change the value of the variable to 1000. When you run the program, nothing will happen when you click the button.

    THE MINNESOTA BASIC CODE 2010 Edition By The League of Minnesota Cities Duke Addicks, Special Counsel Rachel Carlson, Staff Attorney Published by American Legal Publishing Corporation 432 Walnut Street, 12th Floor Cincinnati, Ohio 45202 Tel: (800) 445-5588 Fax: (513) 763-3562 E-Mail: [email protected] Internet: http://www.amlegal.com PREFACE TO THE MINNESOTA BASIC CODE, 2010 EDITION The Minnesota Basic Code This League of Minnesota Cities/American Legal Publishing (LMC/ALP) Minnesota Basic Code (MBC) is an effort to provide a modern and comprehensive code of ordinances for smaller Minnesota cities without the expense of a customized code of ordinances. Its provisions are also useful to all Minnesota cities that wish to have models for the basic city ordinances on the subjects contained in the code. The code reflects current state statutes, case law and rules through January, 2010. The MBC will be supplemented periodically to reflect legislative enactments and new case law and rules. The supplements will consist of new pages which will replace or be in addition to the pages contained in this edition. In addition, the supplements will contain new model ordinances that will be included into the MBC unless the city decides not to incorporate them into their code. Authors and Editors This Minnesota Basic Code is partly based on the Model Ordinance Code for Minnesota Cities, Revised Edition 1980, prepared by Orville C. Peterson, former Executive Director of the League of Minnesota Cities, and the 1989 Model Ordinance Code prepared by Thomas L. Grundhoefer, then Staff Attorney and now General Counsel for the League.

  • Microsoft Small Basic
    Microsoft Small Basic An introduction to Programming Chapter 1 An Introduction Small Basic and Programming Computer Programming is defined as the process of creating computer software using programming languages. Just like we speak and understand English or Spanish or French, computers can understand programs written in certain languages. These are called programming languages. In the beginning there were just a few programming languages and they were really easy to learn and comprehend. But as computers and software became more and more sophisticated, programming languages evolved fast, gathering more complex concepts along the way. As a result most modern programming languages and their concepts are pretty challenging to grasp by a beginner. This fact has started discouraging people from learning or attempting computer programming. Small Basic is a programming language that is designed to make programming extremely easy, approachable and fun for beginners. Small Basic’s intention is to bring down the barrier and serve as a stepping stone to the amazing world of computer programming. The Small Basic Environment Let us start with a quick introduction to the Small Basic Environment. When you first launch SmallBasic, you will see a window that looks like the following figure. Figure 1 - The Small Basic Environment This is the Small Basic Environment, where we’ll write and run our Small Basic programs. This environment has several distinct elements which are identified by numbers. The Editor, identified by [1] is where we will write our Small Basic programs. When you open a sample program or a previously saved program, it will show up on this editor.

  • BASIC Session
    BASIC Session Chairman: Thomas Cheatham Speaker: Thomas E. Kurtz PAPER: BASIC Thomas E. Kurtz Darthmouth College 1. Background 1.1. Dartmouth College Dartmouth College is a small university dating from 1769, and dedicated "for the educa- tion and instruction of Youth of the Indian Tribes in this Land in reading, writing and all parts of learning . and also of English Youth and any others" (Wheelock, 1769). The undergraduate student body (now nearly 4000) outnumbers all graduate students by more than 5 to 1, and majors predominantly in the Social Sciences and the Humanities (over 75%). In 1940 a milestone event, not well remembered until recently (Loveday, 1977), took place at Dartmouth. Dr. George Stibitz of the Bell Telephone Laboratories demonstrated publicly for the first time, at the annual meeting of the American Mathematical Society, the remote use of a computer over a communications line. The computer was a relay cal- culator designed to carry out arithmetic on complex numbers. The terminal was a Model 26 Teletype. Another milestone event occurred in the summer of 1956 when John McCarthy orga- nized at Dartmouth a summer research project on "artificial intelligence" (the first known use of this phrase). The computer scientists attending decided a new language was needed; thus was born LISP. [See the paper by McCarthy, pp. 173-185 in this volume. Ed.] 1.2. Dartmouth Comes to Computing After several brief encounters, Dartmouth's liaison with computing became permanent and continuing in 1956 through the New England Regional Computer Center at MIT, HISTORY OF PROGRAMMING LANGUAGES 515 Copyright © 1981 by the Association for Computing Machinery, Inc.

  • Introduction to Programming with Xojo, Will Motivate You to Learn More About Xojo Or Any Other Programming Language
    Page 1 of 291 Introduction CONTENTS 1. Foreword 2. Acknowledgments 3. Conventions 4. Copyright & License Page 2 of 291 Foreword When you finish this book, you won’t be an expert developer, but you should have a solid grasp on the basic building blocks of writing your own apps. Our hope is that reading Introduction to Programming with Xojo, will motivate you to learn more about Xojo or any other programming language. The hardest programming language to learn is the first one. This book focuses on Xojo - because it’s easier to learn than many other languages. Once you’ve learned one language, the others become easier, because you’ve already learned the basic concepts involved. For example, once you know to write code in Xojo, learning Java becomes much easier, not only because the languages are similar and you already know about arrays, loops, variables, classes, debugging, and more. After all, a loop is a loop in any language. So while this book does focus on Xojo, the concepts that are introduced are applicable to many iii different programming languages. Where possible, some commonalities and differences are pointed out in notes. Before you get started, you’ll need to download and install Xojo to your computer. To do so, visit http://www.xojo.com and click on the download link. Xojo works on Windows, macOS and Linux. It is free to download, develop and test - you only need to buy a license if you want to compile your apps. Page 3 of 291 Acknowledgements Special thanks go out to Brad Rhine who wrote the original versions of this book with help from Geoff Perlman (CEO of Xojo, Inc).
