How do I programmatically convert/merge any doc to PDF in my .NET application?

Question

Please recommend a good library to: 1)Programmatically convert any doc to pdf (word, spreadsheet, presentation, images, html, postscript)

2)Programmatically merge multiple pdf’s to a single pdf (ideally, word_doc1+ ppt_doc2 = out.pdf , in one step)

From .NET/c# app

Thanks

Answer 1

There is an Office 2007 add-in that allows saving to PDF from various Office Programs.

It would be easy to test whether or not its functionality is available programmatically from the COM interface. (i.e. Simply providing a .pdf extension to the file name in the .Save method might suffice.)

Answer 2

If you are OK to let the conversion be carried out on a server in your organisation then have a look at the PDF Converter Web Services. It is scalable, robust, well supported and affordable.

Disclaimer, I worked on this product so obviously think it is fab :-)
