IDirectMusicPerformance::RemoveNotificationType

  • Article

This method removes a previously added notification type from the performance. All segments and tracks are updated by a call to their RemoveNotificationType methods.

HRESULT RemoveNotificationType(
  REFGUID rguidNotificationType
);

Parameters

  • rguidNotificationType
    Reference to (C++) or address of (C) the identifier of the notification type to remove. (For the defined types, see DMUS_NOTIFICATION_PMSG.) If this value is GUID_NULL, all notifications are to be removed.

Return Values

If the method succeeds, the return value is S_OK or S_FALSE (see Remarks).

If it fails, the method can return E_POINTER.

Remarks

S_FALSE is returned when rguidNotificationType is not an active notification.

If a notification was added to a segment that has stopped playing, the performance cannot remove the notification type from that segment because it no longer has a reference to the segment.

Requirements

OS Versions: Windows CE .NET 4.0 and Windows CE .NET 4.1.
Header: Dmusici.h.
Link Library: Dmusic.lib.
