  14. Creating a Project Using Visual Basic .NET • After creating project using New Project dialog box, displayed components are: • Module1.vb document • VB .NET automatically generates some code • Solution Explorer window • Properties window • Contains information about file properties Visual Basic .NET Programming: From Problem Analysis to Program Design

  15. Understanding How VB .NET Organizes Your Programs • Solution Explorer window • Shows hierarchical arrangement of items • File names: • Use .vb extension • Named Module1.vb by default Visual Basic .NET Programming: From Problem Analysis to Program Design

  16. Understanding How VB .NET Organizes Your Programs (continued) • Solution • Container for one or more projects • Must designate startup project • When solution contains more than one project • Project that runs first Visual Basic .NET Programming: From Problem Analysis to Program Design

  17. Using the Text Editor • Provides standard text-editing capabilities • Also provides: • Color-coding • Code indentation • Code completion • Comment • Statement included for documentation purposes only Visual Basic .NET Programming: From Problem Analysis to Program Design

  18. Using the Text Editor (continued) • IntelliSense • Helps you complete lines of code by matching words • Recognizes partial class and method names • Suggests possible matches for name you are typing Visual Basic .NET Programming: From Problem Analysis to Program Design

  19. Visual Basic .NET Programming: From Problem Analysis to Program Design

  20. Modifying the Text Editor Settings • Can change: • Font type • Font size • Color of text in code editor window Visual Basic .NET Programming: From Problem Analysis to Program Design

  21. Renaming Module1.vb • Assign descriptive names to programs you write • Should rename from default names • Use Properties window to change name • Also rename module in source code Visual Basic .NET Programming: From Problem Analysis to Program Design

  22. Setting the Startup Object • Startup object • Module where execution begins when VB .NET runs application • If module renamed: • Must modify startup object • Using Property Pages dialog box Visual Basic .NET Programming: From Problem Analysis to Program Design

  23. Visual Basic .NET Programming: From Problem Analysis to Program Design

  24. Compiling And Executing a Visual Basic .NET Program • Several ways to compile and execute: • Options on Build and Debug menus or toolbars • Shortcut key combinations • Matter or preference • Select Debug on menu bar • Click Start Without Debugging • If there are errors: • Message box displayed Visual Basic .NET Programming: From Problem Analysis to Program Design

  25. Visual Basic .NET Programming: From Problem Analysis to Program Design

  26. Visual Basic .NET Programming: From Problem Analysis to Program Design

  27. Using the Visual Form Designer • Windows application • Runs in Windows environment • Visual form editor: • Windows Form Designer • Can select icons representing various components • Place and arrange components on window • Code is automatically written to match visual form Visual Basic .NET Programming: From Problem Analysis to Program Design

  28. Creating a Windows Application • Use Windows Application template • Use Layout toolbar • To control appearance and position of components • Form grid • Helps to layout components • Not visible when applications runs Visual Basic .NET Programming: From Problem Analysis to Program Design

  29. Visual Basic .NET Programming: From Problem Analysis to Program Design

  30. Creating a Windows Application (continued) • Handle • Use to resize objects • Pointer changes to double arrow • Resize form by clicking and dragging handle Visual Basic .NET Programming: From Problem Analysis to Program Design

  31. Customizing the Appearance of a Form • Modify form elements: • Size • Background color • Title • Name • Position Visual Basic .NET Programming: From Problem Analysis to Program Design

  32. Visual Basic .NET Programming: From Problem Analysis to Program Design

  33. Visual Basic .NET Programming: From Problem Analysis to Program Design

  35. Visual Basic .NET Programming: From Problem Analysis to Program Design

  36. Adding Components to a Form • Use Toolbox • Hidden window on left side of main window • Double-click toolbox items to add to form • When adding buttons • Must identify action that will take place when button pressed Visual Basic .NET Programming: From Problem Analysis to Program Design

  37. Visual Basic .NET Programming: From Problem Analysis to Program Design

  38. Visual Basic .NET Programming: From Problem Analysis to Program Design

  39. Exploring the Debugging Tool • Debugger • Helps you isolate errors • Breakpoint • Flag that tells debugger to temporarily suspend execution of program at a particular point • Can view information about program • May help determine source of problem Visual Basic .NET Programming: From Problem Analysis to Program Design

  40. Getting Started with the Debugger • Debugger • Intended to help identify errors in program that occur while program is running • Cannot help to find coding errors that prevent program from being built successfully • Syntax errors • Helps find logic errors • HOWEVER does not fix them for you Visual Basic .NET Programming: From Problem Analysis to Program Design

  41. Setting Breakpoints • Position cursor in code window • Right-click • Select Insert Breakpoint from popup menu • Program execution is suspended just before line of code where breakpoint is set • Execute program in debug mode Visual Basic .NET Programming: From Problem Analysis to Program Design
