ISpNotifyCallback::NotifyCallback (SAPI 5.4)
ISpNotifyCallback::NotifyCallback is implemented by the client of the SpEventSource object. When this method is called, the wParam and lParam parameters are set to the values specified by the client when it called ISpNotifySource::SetNotifyCallbackInterface. The client should examine the appropriate event source object for events.
HRESULT NotifyCallback( WPARAM wParam, LPARAM lParam );
- [in] wParam parameter is specified by the client when it called the ISpEventSource::SetNotifyCallback interface.
- [in] lParam parameter is specified by the client when it called the ISpEventSource::SetNotifyCallback interface.
Clients should return S_OK. Other values may be used for debugging purposes, but will be ignored by SpEventSource objects.
