How to disable closing the main form in Borland C ++

Question

When closing an application on close button (FormClose handler is called), 
there is a dialog if user is sure that he wants to close the application. 
If the result of the dialog is mrCancel, then I try to set the ModalResult
of a main form to mrNone like I do with other forms, but even though, the 
application still closes.

What is the solution?

Cheers.
