Hello,
Trying to edit memory which guarding with Game guard game.
I can't edit memory when default settings with C.E.
But When I change the Debugging Options->Use windows debugger to use kernelmode driver (Requires DBVM), I can successfully change the memory.

I want to code in C++.
WriteProcessMemory fails, GetLastError returns 5 which is ACCESS_DENIED.

So I want to use dbk32.sys (Cheat Engine's file) to write memory.

But GetProcAddress returns 0.

Need Help, Thanks.

My C++ Code:
Code:
typedef   HANDLE(__stdcall* OPfunc)(DWORD dwDesiredAccess, BOOL  bInheritHandle, DWORD dwProcessId);
typedef   bool(__stdcall* WPMfunc)(HANDLE  hProcess, LPVOID  lpBaseAddress, LPCVOID lpBuffer, SIZE_T  nSize, SIZE_T* lpNumberOfBytesWritten);


HINSTANCE ce_hDLL = LoadLibrary("C:\\Program Files\\Cheat Engine 7.3\\dbk32.sys");   
   if (ce_hDLL == NULL) { // there is no error, loads sys file successfully
      MessageBoxA(0, "Error! Couldnt Load dbk32.dll! Quiting.", "ERROR!", MB_ICONINFORMATION);
      return 7;
   }

   OPfunc OP;
   OP = (OPfunc)GetProcAddress(ce_hDLL, "OP"); // HERE IS THE FAIL. 0

         WPMfunc WPM;
   WPM = (WPMfunc)GetProcAddress(ce_hDLL, "WPM"); // THIS TOO 0

You do not need to open two of the same topic. Stick to the one here:
