Excel prog trial time limit. Need advanced help.
Posted by Josh on December 16, 2001 4:57 PM
I am trying to set up a time limit for how long an excel program can be used. Like 30 days and then the program will not run. I can do it generally by something like = if today() > Enddate etc. but anyone could just change the computer system date and open the program anyways. Is there any way to have excel keep trach of how mutch time has ellapsed since the program was first opened. Total time ellapsed even when the program is closed. I need this to not be effected if the user changes the system date.
Can anyone help me out.
