Danny reported in and showed me some research that he was doing on advanced PDF documents. We have some great code that works for simple to even moderately complex PDF's. This is all part of the merge sub PDF's project for a company. We found that even Adobe Acrobat, the main Adobe PDF product, couldn't handle the crazy complex, encrypted, password protected, postscript, you name it, files and be able to combine and/or merge them. That made us feel a little bit better. Danny will be reporting back to the client to show them what we are running up against.
