We're considering a project which involves reading in various document types (ie. MS Word .DOC, MS Excel .XLS, etc) and then converting them into a single multipaged PDF file. This final PDF file contains all the earlier foreign document information properly formatted as they were intended and can be searched through with the Acrobat search engine. We'd like control over the placement of this information and the ability to create the final PDF on the fly.

We're using C# and Asp.net v1.1 under Windows. Preferably we'd like to interface with some flexibile PDF converter/merger API from our source code or even some quality source code to add to our own.

Can anyone recommend a control, application, open-source, or whatever that can achieve the above?

Thanks for any pointers.
