Installing something to make the program not work after a time.

[Mark]

Hello,

I would like to install something into an exel program
which would either destroy the program, make it not work
properly or erase it completely after a period of time, or
a number of times it has been used. Is this possible, if
so, how do I accomplish it?

thanks

Mark

Destroy (render unusable) the spreadsheet or the
program??? Im sure the worksheet can be done and many
would help with that. I doubt any one will tell you how to
destroy the program.
