    Program a 30-day trial into my Access Program?

    I'd like a potential customer to use my Access Database for 30 days. After 30 days, the program would require an authorization code or password to work. Any thoughts on the best way to do this?

    you want to stay away from password protected access files, unless they are executables. for this reason: http://www.nirsoft.net/utils/accesspv.html

    try an authorization code instead. It's harder to reverse engineer a database file if the code is booting someone out when the wrong code is entered.

    another thought also is to use NUMBER OF TIMES OPENED instead of 30 DAYS. The reason for this obviously is because everyone and their dog knows how to change their windows time clock to an earlier date. All date and time functions in access read the computer's timeclock. So that method will never work, unless you can figure out what MS already knows (or be able to modify the registry to detect these workarounds).

Please reply to this thread with any new information or opinions.
