I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You don't do that exactly, but you can do this.

Capture the Event (Unload) on that form, and choose to close it or not, or to do something else.
Try this:

------

Private Sub Form_Unload(Cancel As Integer)

    MsgBox ("This will appear when I click the x button !!! ")

    if (I_Want_To_Close_This_Window) Then
           
           'Close all files and handles

           Cancel = 0      'This means that this event will get passed on
    Else
           'Do something else

           Cancel = 1     'This means that this event will NOT get passed on
    End If

End Sub

For VB.Net, it's similar...

In VB.Net 2005:

    Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        Select Case e.CloseReason
            Case CloseReason.UserClosing
                If somecondition Then
                    e.Cancel = True
                End If

        End Select
    End Sub
