Your Tech Support is always excellent. I know a bit about that as I used to run an international development team.

I was searching for a way to inject Barcodes into our generated Documents. So i found the Spire.BarCode for .NET library for .Net developers. I've tried it and i was really impressed of how easy it is to use it. We are now using 1 D Barcodes and the 2 D PDF417 Barcode.
Thanks very much for developing such a great Library and all for free.

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.
