dll injection

[dave2k]

i have a dll i want to inject into another process. it conatains a function which overides an api function

i was wondering what the nijection code should look like? something like HMODULE hinstDLL = LoadLibrary((LPCTSTR)"dll.dll");
HOOKPROC hkprcSysMsg = (HOOKPROC)GetProcAddress(hinstDLL, "CallWndProc");


// Set the hook
DWORD ThreadIdCntrl = GetWindowThreadProcessId(windowHandle, 0);
::SetWindowsHookEx(WH_CALLWNDPROC, hkprcSysMsg, hinstDLL, ThreadIdCntrl);?

Syntactically correct, but I am not sure if should work to inject the dll into another process.

Does that work ?

Actually, instead of (LPCTSTR)"dll.dll" you should use _T("dll.dll"). Otherwise it will not work in Unicode mode.
