    WriteProcessMemory help please

    This is the function: (Got it from msdn)

    Code:
    WriteProcessMemory(
      HANDLE hProcess,
      LPVOID lpBaseAddress,
      LPCVOID lpBuffer,
      SIZE_T nSize,
      SIZE_T* lpNumberOfBytesWritten
    );
    link to code:

    http://msdn.microsoft.com/library/de...cessmemory.asp



    But for the handle, how do I do this. Do I use a varible like HANDLE hand = somthing. And how do I get the process handle. I think I can get it but I need to know what it looks like and so on.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    If you dont know what you are doing I'd give that API a miss.

    well I looked at that link and well. I hate to say it but I am not very good at c++ anymore at all.

    I went searching based upon some of that info though and found this function now:

    OpenProcess(
    DWORD fdwAccess,
    BOOL fInherit,
    DWORD IDProcess
    );

    I am thinking this could be used couldn't it?

    I suggest you either make a backup of all your work, because you're just a few mistakes away from hosing your entire machine.

    Or you come up with an explanation of why you want to use something as dangerous as WriteProcessMemory and perhaps we can offer alternative approaches.

    oh alright ok. I am trying to hack my game I made with game maker. And I don't think this is so dangerous. I was told using the registry was dangersous but it isn't if you know what you are doing. And writeprocessmemory shoudl only effect ram/vitual memory right?

    But basicly I want to make a trainer for a game.
