The IASControl interface extends the IDispatch interface. If an application subclasses this interface by exposing an IASClassMsgSink interface, many of these methods subsequently invoke the related IASClassMsgSink method. A pointer to the IASClassMsgSink interface is stored in the control’s ClassMsgSink property.
Some IASClassMsgSink methods can have only a token implementation. They return S_FALSE, indicating that no processing takes place. The IASControl method should be prepared to handle processing in this event.
