Und hier das wichtige aus dem Hauptprogramm:

void CInstallhookDlg::OnOk() 
{
static HINSTANCE hinstDLL; 
typedef BOOL (CALLBACK *inshook)(); 
inshook instkbhook;
inshook instmhook;
hinstDLL = LoadLibrary((LPCTSTR) "InputHook.dll"); 
instkbhook = (inshook)GetProcAddress(hinstDLL, "InstallHookKeyboard");
instmhook = (inshook)GetProcAddress(hinstDLL, "InstallHookMouse"); 
instkbhook();
instmhook();
}

Kann mir da jemand weiterhelfen ??

Ich vermute mal, dass das Spiel DirectInput verwendet und dass dieses jegliche Hooks einfach ignoriert.

echt rofl ^^

HWND TO = GetActiveWindow();
SendMessage(TO,0,message_identifier,mouse_coordinates);

Leider gehts immer noch nicht

Wenn ich im Fenstermodus bin dann funktioniert es auch im Spielfenster aber sobal das Spiel bzw. eine Map geladen ist und das Spiel losgeht funktioniert es nichtmehr.
Aber das war ja vorher schon so
