dll injection

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

Code:

---

        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.
