DLL Injection Method

In this tutorial i'll try to cover all of the known methods(or at least, those that I know =p) of injecting dll's into a process. Dll injection is incredibly useful for TONS of stuff(game hacking, function hooking, code patching, keygenning, unpacking, etc..). Though there are scattered tutorials on these techniques available throughout the web, I have yet to see any complete tutorials detailing all of them(there may even be more out there than I have here, of course), and comparing their respective strength's and weakness's. This is precisely what i'll attempt to do for you in this paper. You are free to reproduce or copy this paper, so long as proper credit is given and you don't modify it without speaking to me first.
