This optional interface provides a simple way for controls to fire events.
Method |
Description |
| IASEventSink::ReceiveMsg | Allows a control to receive a message when a message event is fired. |
The IASEventSink interface extends the IDispatch interface. If an application does not need to receive events, this interface is unnecessary. To implement IASEventSink, create an object that exposes the interface, and place a pointer to it in the IASControl EventSink property. If this interface is not adequate, create a custom IConnectionPoint interface.
