Starting Visual Basic. NET If you are opening VB. NET then you probably want to create applications! Chapter 2 gives you a chance to explore the programming environment! • Integrated Development Environment (IDE) – the part of the VB. NET application that contains windows and toolbars that allow you to develop applications. • A project is a collection of code and other files that usually encompasses one program. 2

VB. NET’s IDE • When the IDE is in Design Time, you can make modifications to the forms and code of a program. 3

Exploring the Visual Basic. NET Integrated Development Environment • Menu Bar – displays the VB. NET menu names each of which represents a list of commands that you allow you to create, edit, save, print, test and run VB. NET applications. • Toolbars – contain shortcuts to commonly used commands. Standard and Layout are two most popular toolbars. • Solution – a grouping of projects and related files.

Running a Project • To test a project you run it. This is usually done by clicking the start button on the standard toolbar. – When you run a project, the project is loaded into memory and the program code is executed by the. NET architecture. – By running your project during the development phase, you can check for problems, or bugs, that you may have introduced into your code inadvertently. – The process of getting your code to work as expected is known as debugging. 5
