catching close button

[lord....@gmail.com]

How can I prevent the big close button in the top of the window from
closing the window?
I want to have and "are you sure?" confirmation so the user must press
"Yes" before the program ends. Right now, I've tried catching the
FormClosing and FormClosed events. The message box appears at the right
time, but since the form is already closing, it doesn't matter if the
user presses "Yes" or "No". how do I cancel the FormClosing?

nevermind... solution is e.Cancel (to stop the Closing event) and
e.CloseReason.
(e is the FormClosing eventarg)

Just in case you (or other readers) may want to know about how to trap
the messages from the title bar buttons (maximize/minimize, restore,
and exit) then here's a post from Herfried Wagner a while back that may
help:

Thanks,

Rowe,

Not in this case, the e.cancel is in this exit question in my idea the best.

I know - whenever I see a post about catching the close button I figure
the next question will be "ok, now how do I trap the other buttons?." I
figured posted it here would help out someone searching the archives
(well, if any one does that anymore :-) )

Thanks,
