How can I perform some actions after the user hits the 'X' in on the form
caption, before my application terminates? Do I need to catch the WM_DESTROY
message for my main form? If that is the only approach, how do I then handle
the message to cancel termination if thats what I want to do? I have
capturing WM's under control, but I just wasn't sure which message I needed
to catch or how to deal with it once I caught it.

Thanks,
Vesty.

Use the form's OnCloseQuery and/or OnClose event.
