The interface for the debugger consists of windows, a toolbar, and a menu bar. The active debugger window determines the commands that are available on the toolbar and menu bar. All commands on the toolbar also are available on the menu bar.
The following screen shot shows the debugger interface.
The debugger interface contains four main windows: Forms, CallStack, Watch, and Immediate. In addition, the debugger can open a code window for each form or module. The Forms window lists the forms and modules loaded in the project. The CallStack window shows currently executing procedures. The Watch window shows the values for a list of expressions, and the Immediate window evaluates statements line by line as you type. The sections that follow describe how to use each of the debugger windows.
