Debugging Your Visual Basic Application

This page provides links to documentation for the debugging features that are built into Visual Studio. For example, you can find semantic errors in your application by observing its run-time behavior in the debugger itself.

By using the debugger, you can examine the content of variables in your application without inserting additional calls to output the values. Similarly, you can insert a breakpoint in your code to halt execution at the point that you specify.

The following table lists debugging tasks involving execution control and provides links to their associated Help pages.
