    Der Code:

    BEGIN_MESSAGE_MAP(RecordSound,CWinThread)
ON_THREAD_MESSAGE(MM_WIM_DATA, OnSoundData)
ON_THREAD_MESSAGE(WM_RECORDSOUND_STARTRECORDING,OnStartRecording)
ON_THREAD_MESSAGE(WM_RECORDSOUND_STOPRECORDING,OnStopRecording)
ON_THREAD_MESSAGE(WM_RECORDSOUND_ENDTHREAD,OnEndThread)
END_MESSAGE_MAP()

    und

    BEGIN_MESSAGE_MAP(PlaySound1, CWinThread)
	ON_THREAD_MESSAGE(WM_PLAYSOUND_STARTPLAYING, OnStartPlaying)
	ON_THREAD_MESSAGE(WM_PLAYSOUND_STOPPLAYING, OnStopPlaying)
	ON_THREAD_MESSAGE(WM_PLAYSOUND_PLAYBLOCK, OnWriteSoundData)
	ON_THREAD_MESSAGE(MM_WOM_DONE, OnEndPlaySoundData)
	ON_THREAD_MESSAGE(WM_PLAYSOUND_ENDTHREAD,OnEndThread)
END_MESSAGE_MAP()

    Wie kann ich das Problem lösen?
