1306 Visual Studio .NET Debugger Appendix D
Figure D.6 shows the IDE with program execution suspended at a breakpoint. The
yellow arrow to the left of the statement
x *= i
indicates that execution is suspended at this line and that this line contains the next statement
to execute. Note that the title bar of the IDE displays [break]—this indicates that the
IDE is in break mode (i.e., the debugger is being used). Once the program has reached the
breakpoint, you may “hover” with the mouse on a variable (in this case x or i) in the source
code to see the value of that variable.
Testing and Debugging Tip D.3
Loops that iterate many times can be executed in full (without stopping every time through
the loop) by placing a breakpoint after the loop and selecting Start from the Debug menu. 24.0
D.3 Examining Data
Visual Studio .NET includes several debugging windows, all accessible from the
Debug > Windows submenu. Some windows are listed only when the IDE is in break
mode (also called debug mode). The Watch window (Fig. D.7), which is available only in
break mode, allows the programmer to examine variable values and expressions. Visual
Studio provides a total of four windows that allow programmers to organize and view variables
and expressions.
