Not too long ago I was looking at the various PDF components because I wanted to help a family member with a business problem they were having. There were products out there that did all the things they wanted but the cost was prohibitive for them. Unfortunately, at the time I was unable to find a viable solution but I just stumbled across a blog entry with a story similar to my own and an answer to the problem. I hope to check out PDFSharp in the near future to determine if it meets my needs. Have you used this product? Any problems to report?
