The examples here are limited to a description of the procedures associated with completion of a PDF; the download will contain examples of PDF creation in both Visual Basic and C. The examples contained herein are dependent upon the availability of the iTextSharp DLL; use the link provided previously in order to download the DLL locally to your development machine. The form contains controls and may be filled out programmatically so it serves as a good example. PDF documents that do not contain controls; those meant to be printed and filled in with a pencil, cannot be completed using this approach. Further, though not demonstrated here, one can also use iTextSharp to create a PDF document with embedded controls.

We need to do the following from our website 1. Serve PDF fillable forms to end users. Prefill some fillable fields programatically before serving form. Currently using iTextSharp library. Allow user to save filled PDF form. Lock down non-editable fields.
Allow end user to programatically prefill editable fields on forms from their database without letting them unlock or modify other form content. Are there any adobe products that will support our requirements on an ASP. Net site? Thanks, Mike. Michael Brietzke.
The answer is yes, sort of. It all depends on how you go about it. Adobe ColdFusion has some very nice form handling features, and it sort of resembles a programming language. But you don't need it. And unless you are a rich masochist, I wouldn't bother looking at the LiveCycle servers. You can do this all on your own with ASP and iText. And there are lots of other server side PDF libraries and tools out there, but nothing compares to iText except maybe the official PDF Library , if you know what you are doing.
So first, why do you need Reader Enabling? You've got programming skills, there is no need to submit whole forms or for the user to save the exact form they fill out. Do all your transactions through data. If the user needs a local copy, then built a printable flat version on the server and push it up to the user. Acrobat is cabable of handling prefill and automatic modification. Acrobat automatically loads the PDF and merges the data, preserving any Reader Extensions if you really need them.
So it is not absolutly necesary to prefill on the server. Then modifications can be made at run time through submits to a server script which returns a data file. Locking and unlocking can be done with scripts, either on the form or remotely through returned FDF that contains a script.
