Thread: Closing all forms from a derived form

Is it possible to inherit from a form and in that new derived form close ALL forms?

So in the derived class you would have something like:

Code:

protected sealed override void Exit(object sender, EventArgs e)
{
    // exit all forms here.
}

this.Close(); and base.Close(); just close the new instance of the form.

Oh by the way I realise there's the Application.Exit(); function but what I'm after is how to access the controls/form on the derived instance.

Example - how would I rename a label on the derived form, or create an event that is not implemented in the base form?
