Greetings

Does anyone have a clue regarding the following questions? I'd like to know
how to place a generic breakpoint within an application that is in debug
mode, and another one; how to do generic single step execution of the
software in debug mode. This all regards win32 applications.

Thank You all and I wish You the best of everything
Bruno

If you have access to the source code and you're running your application
through a debugger (such as from inside Visual Studio's Visual C++ IDE),
then all you need to do is add "int 3" or "_asm int 3" if you're in C/C++
mode.

It will trap back to the debugger whenever int 3 is encountered. From there
you use the capabilities of the debugger to single-step, report memory
regions, etc.
