I have build a model in excel that includes alot of Sheets, Charts and VBA procedures. The user interface works through forms. I have protected this model by making all the sheets VERYHIDDEN and putting a password on access to the macros.
Question1: Is there any additional passwords I can use to protect this program?
Question2: Is it possible to block the program a certain period after it was first opened. Example, it should only be valid for one month.
