I have after buying David and Raina Hawley's book, Excel Hacks, implemented their password protection (Hack 130) in one of my workbook. However it has one downside that I wonder if there is a way to trap this. When I or someone else than me opens the workbook then excel displays a Security Warning that this workbook contains macros. If I choose Disable Macros then anyone can see my work. Is there a way to shut down the workbook if someone chooses to open the workbook without macros?
