Is there any way to keep MapPoint from exiting when a user tries to quit it. I have an application that uses MapPoint primarily in the back ground, but I allow MapPoint to be visible for the purpose of looking at routes and getting route related information (in the future it will support pseudo multiple routes). The problem is that if I close MapPoint from the MapPoint window rather than from my application's "Hide MapPoint" button, the application will crash. I have tried reinstantiating the MapPoint.ApplicationClass class when a MapPoint._ApplicationEvents_QuitEventHandler event occurs. I even set all MapPoint related identifiers to null. This does not work as expected. The application will still crash. Has anyone ever tried to do this? How do you get it done?

From memory, I think the quit event handler returns a value, allowing you to disable the quit behaviour??

If not, you could use the MapPoint control instead of the standalone app. You could also control/disable other user-interaction actions as well, then. It may also look more seamless for the user?

The quit event cannot be cancelled, according to MSDN Library.

I don't know why, but I can't seem to disable user control. Seems like the MapPoint control is my best option. I agree that the look of the UI will be more cohesive that way. Even though the UI looks good now, better is always best (when feasable of course).

I went ahead and used the control. Didn't take more than 10 minutes to get worked out. Thanks for the suggestion.
