Is there any way to programmatically enable Adobe PDF usage rights from .net code ? I\'m using ITextSharp library to fill an XFA Form with XML Data (generated from app), but
No. Adobe uses Strong Crypto to ensure it... PPK I believe.
Google is saying that "Only Adobe products can do that"
That's because only Adobe products can do that. You can pay for some Acrobat server product or other... $$$... but that's it.
