Your Tech Support is always excellent. I know a bit about that as I used to run an international development team.
I am always pleased to see people that are careful and professional in the way they deal with customers and help customers to get the best result.
You and your colleagues are very good, so thanks again!

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.

Our team was in need of a .NET utility that would allow us to generate barcode images used for emailing receipts.
Spire.Barcode not only provided the ability to generate barcodes and save them as images, but offers a range of customization that suited our needs perfectly.
The fact that these services are completely free is almost too good to be true!
