I convert html to pdf using doc.Security.Disallow(PdfDocumentPermission.ModifyingContents) and doc.Security.Disallow(PdfDocumentPermission.CopyingContents), but I can still open the resulting pdf file in Adobe Pro and do editing and copy/paste. How can I prevent editing/copying regardless of what program people use to open the pdf? Please help. Thanks. PS. In Adobe Reader the edit button is disable correctly and as desired I cannot do copy and paste.

Hi,
I do not believe there is anything you can do to prevent a file being edited by Adobe Pro. The security setting is merely a flag in the file. A program can choose to honor it, as most readers do, but programs like Adobe Pro that is meant to modify files would have reasons to disregard it. Otherwise an author would not be able to create contents of "locked" PDF file properly with Adobe Pro.
Thanks!
