UltraMessageBoxManager can be closed using Alt+F4
posted

The UltraMessageBoxManager forms can be closed using Alt+F4.  When this occurs, they do not return with one of the expected DialogResult values.  The x in the upper right-hand corner is disabled (which should normally indicate that they have to select one of the available options to continue and cannot close the form with Alt+F4).

The standard Windows MessageBox form cannot be closed with Alt+F4.  You always have to click a button (or press enter/escape).  As a result, they always return one of the expected DialogResult values.  Is there a way to disallow the user from closing an UltraMessageBoxManager form with Alt+F4?  Is this a bug or how it is supposed to work?

    Hi,

    I tried this out with a variety of different settings and options, but in all cases, both the inbox MessageBox and the UltraMessageBox display with the close button enabled and Alt+F4 works for both of them.

    Can you post the code you are using to show the MessageBox so I can use the same options you are using?
