How to best combine the information on the server into a "form", as a final output, a PDF file is created

Background

I have a VB6 application that I “inherited” that creates a PDF file for user to view using the unsupported Acrobat Reader OCX integration. The program generates an FDF file with data, and then displays the combined result when the FDF is combined with the PDF. It works only with Acrobat Reader 4 :-( Installing a new version of Acrobat Reader violates this application, which makes users very unhappy.

I want to reverse engineer this application so that it sends the data that needs to be combined to a PDF output generation server. This server will combine the data submitted to it in the form, create a PDF image of this and save it so that any user who wants to view the final result can simply get a PDF file (it is generated only once). If the baseline data is changed, the PDF will be deleted and regenerated at the next request. The client program can then have any version of Acrobat Reader that they want, as it will be used exclusively for displaying PDF files (as intended). The server will most likely be written in .NET (C #) with Visual Studio 2005, possibly as a web service ...

Question

How do others recommend doing this? Should I use Adobe Acrobat 9 on the server for this, putting the data in FDF or Adobe XML format and letting Acrobat do the merge? Are there any major competitors in “combining form data and PDF output”? How do others do it? Of course, it should be based on an API, without a GUI on the server ...

Check out pdfTron (google it) and see if it will do what you want. Then you need to find out what license you need and how you are going to pay for it. If someone comes up with something better, hope they vote for him at the top of the list.
