Preventing an MDI child from closing

I have an MDI application in which I want to get notified when a child is closing and then check to see if modifications were made.  If so, I want to put up a "Save? Yes, No, or Cancel" dialog and if they select cancel, prevent the child from closing.  OnDestroy in my view class is too late.  Any ideas?

If OnDestroy() is too late, what about OnClose()?
It gets called before OnDestroy().

I'm not sure why OnClose or WM_CLOSE are not one of the messages available in ClassWizard for my view class.  If I put in in by hand it does not appear to get called before (or after) OnDestroy.  I would have though it would have too.

Sorry for not specifying - I meant you should try to override the OnClose() member of your frame window. It gets the WM_CLOSE message in place of the view.
