>Another thing to bear in mind Michael, is , how were the pdf's created ? I had a task to strip the text out of thousands of pdf's - using IText ( part of ItextSharp library I seem to remember ) and the ones (pfd's) that were created by scanning a document didn't have any text at all as the text is embedded as a graphic.

Yes, I know. This is why I was looking for something that would be very good. The only think that can read for sure all PDFs seems to be their own tool, such as Acrobe Reader, but it would be nice to have those librairies included in the .NET Framework.
