I would like to create a dwl file through automation, so users get a message when opening drawings that have changed ownership to other offices. I have done this, but it does not seem to work. Is there a format that I need to follow to get it to work? After I create the dwl file for a drawing, it simply opens the drawing and overwrites the one I created. No message. Can AutoCAD really be that smart?

Thanks for any help I can get.
