Here [0] you have a nice example on how to prevent the user from
closing the progress window.

If you look closely, you will see that at the Form_Close event, if the
user is not allowed to close the window ($bCanCancel == False)  then
the close event is stopped, and the operation continues. This variable
should be set when you start executing the process you need to inform
the user about.

Public Sub Form_Close()

  If Not $bCanCancel Then
    Stop Event
  Endif

End

Hope it helps!
