Viewing Information in the Watch Window

   

The Watch window allows you to monitor the values of variables, properties, and expressions at run time. Many debugging problems aren't immediately traceable to a single statement, so you may need to use a watch expression to observe the behavior of a variable or expression throughout a procedure.

The development environment automatically monitors the watch expressions you define. When the application enters break mode, these watch expressions appear in the Watch window, where you can observe their values.
