Stopping Form from Unloading

How do I stop the application from unloading if the window close button (X - top right-hand side of the window ) has been clicked in error. I can interrupt the unload event to safeguard data, but using 'exit sub' does not give me the desired affect.

Check out the QueryUnload event, if the variable 'UnloadMode' is equal to vbFormControlMenu then the user has used the 'X' button to close the window. Change the value of the variable 'Cancel' to True to abort unloading.

Somehting like this..

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

  If (UnloadMode = vbFormControlMenu) Then
    Cancel = True
  End If
End Sub
