I have this great little application / macro that was written by E-E Professionals. I use it to insure that control can be maintained over spreadsheets that proliferate within an organization. I need one little addition. I need the ability to run a small macro that locks either the spreadsheet or the workbook so that after the date passes, you must enter a new password. I would like this macro also to force a user form that directs the user on where to go to get the password.
