13. 13 To Start Visual Studio.NET and Customize it for Visual Basic.NET Development 1.Click Start on the Windows taskbar, point to Programs (All Programs in Windows XP), point to Microsoft Visual Studio.NET, and then click Microsoft Visual Studio.NET 2.In the left pane of the Start Page, click My Profile

14. 14 My Profile, From the Visual Basic.NET Start Page

15. 15 To Start Visual Studio.NET and Customize it for Visual Basic.NET Development (Continued) 3.In the Profile combo box, look at all the options in the drop-down list, and then click Visual Basic Developer 4.In the Keyboard Scheme list box, click Visual Basic 6, if necessary 5.In the Window Layout list box, click Visual Studio Default, if necessary 6.In the Help Filter list box, click Visual Basic, if necessary 7.In the At Startup list box, you can make whatever choice is most comfortable for you. In this situation, click the default, Show Start Page

16. 16 Creating and Opening a Visual Basic.NET Solution and Project Solution –A container for one or more projects Project –Consists of a computer program and related components, written in one of the programming languages supported by the Visual Studio.NET platform Files that constitute a project –Stored in the solution container Solutions that you create –Consist of a single Visual Basic.NET project Solution and project refer to the same Visual Basic.NET application

17. 17 To create a New Project and Solution 1.Click Get Started on the Start Page, and then click New Project 2.In the New Project dialog box, click Visual Basic Projects under Project Types, if necessary 3.Under Templates, click Windows Application, if necessary.
