Hi!

When setting e.Cancel = true in a forms Closing event, you can prevent
the form being closed. I did so, but on my form I have a button with
DialogResult set to Abort, but the form doesn't close now that I've set
Cancel to true.

How can I work around this so that you cannot close the form by using
Alt-F4 but still allow the controls to call the Close method of the form?

Thanks in advance,
Patrick

Click to expand...

Remove the 'DialogResult' from the button and add this code in its
'Click' event handler:

\\\
m_Close = True
Me.DialogResult = DialogResult.Abort
Me.Close()
///

On top of the code you add:

\\\
Private m_Close As Boolean
///

In the 'Closing' event handler you check 'm_Close' and set 'e.Cancel' to
'True' only if it is not set.
