Well this thread looks like its starting to get a little stale so I will post this here too in the hopes of helping out the programmers still around here.
I came across this resource kit from Microsoft called Detours that is basically a package of tools/code to bypass windows API's and win32 applications lmao it was released by Microsoft Research. So for those of you working on a bot like me, give this a look, I think it can be of great help.
