Remarks

This is the only exposed function for the Voice Recorder control. The Voice Recorder control is implemented in VoiceCtl.dll and responds to messages from its owner application. Specifically, the owner window can access the recording process by using the following messages: VRM_RECORD, VRM_PLAY, VRM_STOP, VRM_CANCEL, and VRM_OK. In addition, the Voice Recorder control can send notifications to its parent window using a NM_VOICE_RECORDER structure. This structure can contain the following messages: VRN_RECORD_START, VRN_RECORD_STOP, VRN_PLAY_START, VRN_PLAY_STOP, VRN_CANCEL, VRN_OK, and VRN_ERROR. NM_VOICE_RECORDER can also contain the error values described in the following table.
