Weird Problem: Closing MDI Parent re-directed to MDI Child

by: Charles Law | last post by:

For some reason, when I click the X to close my MDI parent form, the action appears to be re-directed to one of the MDI child forms, and the parent remains open. I am then unable to close the application. What should happen, is that the main MDI form should close, taking the child forms with it. There is code to loop through the child forms,...

I guess what I'm asking is will that work. If one form sets e.cancelled to true will e.cancel be...
