0x0 |
Specifies the key that, when pressed, establishes a breakpoint in code being debugged.
The debugger interrupts code processing at the breakpoint so the programmer can examine a suspected problem.
The key specified in this value only sets a breakpoint. It does not invoke the debugger (the debugger must be running before the key is pressed), and it does not switch the debugger to single-step mode.
The value of this entry is a keyboard scan code. The default value (0x0) represents the F12 key on a 101-key keyboard or the "-" (hyphen, VK_SUBTRACT) key on an 82-key keyboard.
The following table lists the scan codes and virtual key codes for a standard keyboard.
