Cannot open wow process

[SA56-Scorpion]

hi...
i've got a big Problem. I cannot open the WoW process with "PROCESS_ALL_ACCESS". By changing the access-level, e.g. to "READ_CONTROL", then ReadProcessMemory doesn't work anymore.

int main()
{
	HWND hWnd = FindWindow(0, "World of Warcraft");
	if(!hWnd)
	{
		MessageBox(0, "Error cannot find window.", "Error", MB_OK|MB_ICONERROR);
		return 1;
	}

	DWORD ProccessID;
	GetWindowThreadProcessId(hWnd, &ProccessID);
	HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, ProccessID);
	if(!hProcess)
	{
		MessageBox(0, "Could not open the process!", "Error!", MB_OK|MB_ICONERROR);
		return 1;
	}

	uint32 buffer = 0;

	if (!ReadProcessMemory(hProcess, (void *)(0x05AF3F6C), &buffer, sizeof(uint32), 0))
	{
		MessageBox(0, "Could not read memory!", "Error!", MB_OK|MB_ICONERROR);
		return 1;
	}

	CloseHandle(hProcess);

	system("pause");

	return 0;
}

In one of these steps i always get an error...
can you help me plz

Sigh, not this shit again.

I'm not even going to read your code, but I can tell you now it's almost certainly because you're using PROCESS_ALL_ACCESS without setting the correct Windows header target version.

Process Security and Access Rights (Windows)

Either set the target version to XP (or w/e your minimum OS target is), or, the better solution is to simply manually xor together the flags that you actually need, rather than just asking for everything, including shit you're not going to use.

i don't understand what you mean... you say that the problem is the PROCESS_ALL_ACCESS flag. OK, the size of this flag increaed with vista an Windows server 08, so i cannot use this flag on windows XP without changing the version... but i have got windows vista...

and another thing... which flags do i need for reading only?

dewd, enable your brain and read the msdn page that you were pointed out to read.
it does explain how to properly set the PROCESS flags and how they work on different versions of windows, just use your goddamn brain buddy.
And if you aren't already doing it, I doubt you are since it's not in your code, enable SeDebugPrivilege before calling OpenProcess...
Changing Privileges in a Token (Windows) ****ing read it

I've already supplied you with all the information needed to fix your problem. Read the MSDN page and figure it out, I'm not going to spoonfeed you.
