Both Spire.Doc and Spire.XLS are great!
They helped me write a tool that I use in my work for the automated execution of documents. Thank you very much!
I am very happy with these libraries and I will definitely recommend them to my friends.
Best regards, Jacek from Poland.

It seems your Spire.PDFViewer component was precisely what we needed. And your demo included in the installer was very much helpful.
Our solution including your Pdf viewer is fine for now.
