MDI Children Closing Event Not Firing

[Barry Gast]

Hi. I have an MDI Parent form with multiple child windows. When I close
the parent form, the Closing events of the children forms are not executing.
Do I have to close all the child forms in the parent's closing event in
order to get the closing events of the children forms to execute?

Thanks.

Possibly not exactly what you are looking for but I would
use this to close all active children:

\\\
Dim frmChild As Form
For Each frmChild In Me.MdiChildren()
Me.ActiveMdiChild.Close()
Next frmChild
///


Regards Steve

That works for the events, but now I can't seem to get the
CancelEventArgs.Cancel property to "bubble-up" back to the parent MDI form
to prevent it's closing.

Any ideas?

No, the Closing events should fire in the child windows. How do you close
the MDI parent? If you call application.exit or even execute "End", the app
is killed the hard way => no closing events fired.

DOH!

That was it.

Thanks Armin.

HOw do you do it now?

The closing events of the child forms now fire, and the cancel property of
the CancelEventArgs parameter "bubbles-up" back to the MDI form.

My close function originally had the Application.Exit command in it, which
by-passed all the closing events of all the forms. Now I just issue a
Me.Close command for the MDI Parent form, and my Sub Main() handles the rest
of the application closing functions.

Thanks!
