Microsoft DirectX 9.0


The GetNotifyFlags method determines whether event notifications are enabled.


HRESULT GetNotifyFlags(
  long *lplNoNotifyFlags



[out] Pointer to a variable that receives one of the following values:

Value Description
Zero Event notifications are enabled.
AM_MEDIAEVENT_NONOTIFY Event notifications are disabled.

Return Value

Returns S_OK if successful, or E_POINTER if the lplNoNotifyFlags parameter is NULL.


By default, the Filter Graph Manager posts event notifications for the application. To disable event notification, call the IMediaEventEx::SetNotifyFlags method with the value AM_MEDIAEVENT_NONOTIFY.

If event notifications are disabled, the handle returned by the IMediaEvent::GetEventHandle method is signaled at the end of each stream—that is, whenever the Filter Graph Manager receives an EC_COMPLETE event.
