Hi Cathi,

Well I did that but it didn't work, but when I checked your code I see it didn't work because I was using the OnClose: (from the Overrides menu??)

Protected Overrides Sub OnClosing(ByVal e As System.ComponentModel.CancelEventArgs)
...
...
End Sub

While i should use the form cosing event!!

Thanks Cathi.

>>>Ahmad,
>>>You need to call the PerformClick method to raise a button's click event, as in:
>>>
>>>btnExit.PerformClick()
>>>
>>>In the example you had, you might also consider using the ButtonCancel property for the form, so when they press escape it calls the button's click method, as in:
>>>
>>>Me.CancelButton = btnExit
>>>
