OnMsgMonitorPointUpdateEvent
Summary An event that is generated whenever a message tag monitor
point update is received .
The OnMsgMonitorPointEvent event is used to signify
asynchronous successful completion code events for a
message monitor point. The OnMsgMonitorPointErrorEvent
is used to signify asynchronous unsuccessful completion code
events.
If you are using a programming environment which supports
multi-threading (such as Visual C++), you can receive update
events on a separate thread by creating an object which
implements the ILcaMsgMonitorPointListener interface.
