Wozu willst du denn bitte WM_TIMER abfangen, du hast du schon eine Callback-Methode definiert

Zitat:
pTimerFunc
[in] Pointer to the function to be notified when the time-out value elapses. For more information about the function, see TimerProc. If lpTimerFunc is NULL, the system posts a WM_TIMER message to the application queue. The hwnd member of the message's MSG structure contains the value of the hWnd parameter.
