Danke SilverFire, aber bei mir crasht das Spiel (egal welches Dx9 Game),
wenn ich die Funktion im HookThread aufrufe. Code:

HookThread:

Spoiler

CPP Code:

 
DWORD WINAPI HookThread(void)
{
	while(!hModule)
	{
		hModule = GetModuleHandle ("d3d9.dll");
		Sleep(200);
	}
 
	dwGlobal = dwFindPattern((DWORD)hModule, 0x128000, (PBYTE)"\xC7\x06\x00\x00\x00\x00\x89\x86\x00\x00\x00\x00\x89\x86", "xx????xx????xx");
	memcpy(&VTableStart, (void*)(dwGlobal+2), 4);
	pEndScene = ( EndScene_t )HookVTable( (DWORD**) dwGlobal, 42, (PBYTE) hkEndScene);
	return 0;
}

HookVTable:

Spoiler

CPP Code:

 
PBYTE HookVTable(DWORD** VTablePtr, int VTableIndex, PBYTE HookPtr)
{
	DWORD oldProtect;
	VirtualProtect((void*)((*VTablePtr)+(VTableIndex*sizeof(DWORD))),sizeof(DWORD),PAGE_EXECUTE_READWRITE,&oldProtect);
	PBYTE original=((BYTE*)(*VTablePtr)[VTableIndex]);
	(*VTablePtr)[VTableIndex]=(DWORD)HookPtr;
	VirtualProtect((void*)((*VTablePtr)+(VTableIndex*sizeof(DWORD))),sizeof(DWORD),oldProtect,&oldProtect);
	return original;
}
