How to stop copying of workbook

[Paul Aug]

I have created an excel work book to sell and would like to know how can I prevent anyone stealing my creation, I intend on copying to a memory stick but really need to stop anyone copying my the whole workbook please.
All help would be gratefully received
Many thanks

I dont think you can really stop users from doing that if you're going to sale it. because if you give it to one user they can easily shareit with other users too..
If you just want them to have a sheet from your workbook why not, just build a sheet which you want other users to have it? and u keep the rest...
But i think the inquiry is also not that clear...

This isn't really an Excel question: you need to work out how to stop someone copying the file off the memory stick.

You can timebomb the workbook say for a period of 30 days.
