I want to prevent any document from Copy and paste but i want from database level because in veiw level there is option querypaste but this need to do in every view so there is any option where i can write a code in database level so that it applicable in all view .
Subject: RE: Prevent Copy and Paste Document from Database
Users can get around the view code by creating a private view.
There is also the Form property “Disable printing/forwarding/copying to clipboard”, and the ACL setting for “Copy or replicate dpcuments”, which can be disabled for some or all users – but there are ways around this, too.
There is no foolproof way to prevent copying. If you can read it with Notes, you can read it with your own code, and your code can do whatever it pleases with it, including writing it to another database.
This is one of the longest discussion threads I’ve ever seen but it gets into a ton of security issues. Bottom line is exactly what Rich suggest: If they can see it, they can take it.
