Icon Description
In some cases, MSDEV wont allow to set break point event if we press F9 a number of times. In those situations you can hardcode a break point by yourself.

Icon How Can I Do It?
Just insert the following line to the point where you would like to break while executing.

__asm int 3;

VisualStudio uses Interrupt 3 for implement break points. When we put a breakpoint, actually the debugger is inserting an int 3 instruction at that point. While executing, when an interrupt 3 is raised – debugger understood that one breakpoint is reached and it breaks and shows the appropriate code.
