Hello,
First of all, my last project required me to make an .exe self-injector, so I have experience in this type of projects.
I have an already-working thread injection library. I made it work on both Windows 7 32bit and 64-bit. I can say that I have more than 80% code for this project, and putting everything into a loop to check for PID change is easy.
Also, I have a set of demo apps (injection target, test dll, injector) to show you if you want.
I hope that was enough to assure that I can do this project. If you have any questions, please send a PM.
