Commonly used code injection tools to implement code injection and DLL injection, first of all, I find the game's call, walk walk with injection tools into the call code l is feasible, people can walk in the game, but I think of that piece of code written in vc6 dynamic link library, compile success and generate DLL, and then use the code into this DLL injection tools to the game, people can't walk, at the same time, in order to test whether injection is successful, in the code I added a pop-up messagebox are successful pop up, but man can't walk), don't know is what reason, what who can tell me?
