Help for VB.NET 2003

You can press F8 and your app will start and execute one line of code at a time. This is the same for all versions of .NET. You may also want to place a breakpoint somewhere in your code to stop execution of a running app so you can inspect values of objects/variables etc and even continue by using the F8 or return to run mode with F5. You can add a breakpoint by left clicking in the left hand margin column of the code behind editor. A red line will appear on the line of code you placed the breakpoint on.
