C# 5.0 Programmer's Reference

The Breakpoints Window ❘ 235
➤➤
Modules—This window displays information about the DLL and EXE files used by the
program. It shows each module’s filename and path; whether it is optimized; whether it is
your code (rather than an installed library); and whether debugging symbols are loaded. It
also shows each module’s load order (lower-numbered modules are loaded first), version,
and timestamp.
Often it is useful to make the visible debug windows occupy separate tabs in the same area at the
bottom of the IDE. That enables you to switch between them quickly and easily without them
taking up too much space.
The Breakpoints Window
The Breakpoints window lists all the breakpoints. If you double-click a breakpoint in the list, you
can easily jump to the code that holds it.
The icons to the left of the breakpoints shown in Figure 10-2 give information about their properties.
The following list describes the icons.

Solid red circle—This indicates an ordinary breakpoint.
White plus sign—This indicates the breakpoint is modified by a condition, hit count, or
filter. The following text describes these.
Diamond—This indicates the breakpoint performs some special action when it is
reached. Normally, the action prints a message in the Immediate window showing
values that you specify.
Hollow circle or diamond—This indicates the breakpoint has been disabled.
Right-click a breakpoint and select Condition to display the dialog box shown in Figure 10-3. By
default, a breakpoint pauses execution whenever it is reached. You can use this dialog box to add an
additional condition that determines whether the breakpoint pauses the program when it is reached.
In Figure 10-3, the breakpoint pauses execution if the expression (number < 10) && (i > 5) is
true when the code reaches the breakpoint.
Figure 10-3: The Breakpoint Condition dialog box
enables you to specify a condition that determines
whether execution pauses at the breakpoint.
