Hi Everybody:

    I am writing an ArcMap 10 extension using C#. I want to detect the user's mouse click on the map. However, I haven't successfully get it done.

    I notice that IMapControlEvent2 should give a delegate to handle the event, but I don't know how to get IMapControlEvent2 out of the current application. I did the following but it doesn't work:
IActiveView view = (_mApplication.Document as IMxDocument).ActivatedView;
IMapControlDefault mapControlDefault = new MapControl();
mapControlDefault.Map = view.FocusMap;
IMapControlEvents2 mapControlEvents = mapControlDefault as IMapControlEvents2;

    How shall I do it?
    Thank you!
