■ Removes all breakpoints in your project. Breakpoints tell Visual Basic to halt just before a specific line of code. ■ Use breakpoints to halt your project at a point where you suspect problems, then: • Test the values of variables in the Immediate window or with the Instant Watch command • Add variables to the Debug window and single step your project from the breakpoint forward ■ Tip: Use Toggle Breakpoint (or press F9) to turn individual breakpoints on or off.
