[RESOLVED] the v.b form should not be closed even, user pressed close button,how?

I would find an application I can not close to be most annoying.

Why do you want to build this into your app?

Incidentially, if I encountered such an app, I would simply call up Task Manager, terminate the program, and never use it again.

I agree. It's one thing to have the user confirm they want to exit. Another thing entirely to use an exit button for another purpose.
