Time Trial for excel files

[The Boondock Saint]

Is there anyway you can put a certain time trial into an excel file, so that
you can let people view it... but after say 7 days the file will no longer
open?

 

[Harald Staff]

There is no bulletproof way of doing this. All solutions rely on macros
being enabled and running. Make toe file useless without macros and put all
your evil creativity into the timer macro.

Best wishes Harald

Not reliably.

You can search the archives:

for example, using the keyword "expiration", but all the methods are
rather easy to defeat.

XL03's DRM provisions, in combination with a Windows 2003 Server may
work for you, if your users can access the file.
