I am using Visual Studio, developing a native application, I have a programmatical breakpoint (assert) in my code placed using __asm int 3 or __debugbreak. Sometimes when I hit it, I would like to disable it so that successive hits in the same debugging session no longer break into the debugger. How can I do this?
x86 / x64
Assuming you are writing x86/x64 application, write following in your watch window:
x86:
*(char *)eip,xx64:
*(char *)rip,xYou should see a value 0xcc, which is opcode for INT 3. Replace it with 0x90, which is opcode for NOP. You can also use the memory window with eip as an address.
PPC
Assuming you are writing PPC application (e.g. Xbox 360), write following in your watch window:
*(int *)iar,xYou should see a value 0xfeNNNNNN, which is opcode for trap (most often 0x0fe00016 = unconditional trap). Replace it with 0x60000000, which is opcode for NOP.
