Also, the Chapter 8 example, part2.chapter08.ReaderEnabledForm worked with all iTextSharp 5.XX versions, and just confirmed it works with iTextSharp 5.0.4.0 too. ------------------------------ Message: 3 Date: Mon, 23 Aug 2010 14:46:26 +0100 From: Calvin Streeting <calvin.street...@bailygarner.co.uk> Subject: [iText-questions] delete temp files after streaming to client?

If all is still not really clear for me, I managed to create and then sign the pdf using a MemoryStream object (equivalent to ByteArrayOutputStream in java I guess). I'm going back to learn this library, thanks again. Best regards, leparachute.
