Program expiry date + passwords

  • Hi all

    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.

    Your project is probabaly as secure as Excel will allow.

    There are lots of ways, some examples on the Board - use Search. They usually include a an expiry date hidden in the workbook and a macro to compare the actual date against the current date. Not completely foolproof though.
