I have used Micorsoft COM API for Excel/Word processing but encountered many problems. Then I try Spire these two weeks and find it powerful and easy to use.
I also post some issues on the forum and get replied at the right time, so grateful. I have used Free Spire.Doc and Free Spire.XLS in my project and they work well in my application.
Currently the free components have satisfied my needs. I will consider for commercial product if necessary.

We are using the 100% free Spire.Barcode from E-iceblue in our windows test applications and it is all what we need. Featuring an easy integration into our test environment Spire.Barcode helps us improve our product quality. Its free and easy to use and Transtronic programmers are looking forward to use Spire barcode in future projects.

Please let everyone there know that I could not do my job here without this SDK Spire.PDF and the amazing support that I get from you folks when I have questions.

I included Spire.PDFViewer in my application now and it works very fine. The integration was fast and easy. Great product!

I have copied license file in the VS library project wich use it, and declare as embedded resource.
So in Constructor of my class, I simply added:
Spire.License.LicenseProvider.SetLicenseFileName("spire.pdf-license.elic.xml"); //
Active la licence d'utilisation pour supprimer le logo E-ICEBLUE and all is OK !
I receive no more the evaluation message.
Thanks to you and to the development team: Spire.PDF is a very good product!

Installing and setting up the E-iceblue Barcode generator into Visual Studio was easy and straightforward.
The generator is brilliant. Within a short while I was creating bar codes within my application. I would recommend E-iceblue products to anyone who wishes to install a seamless mechanism into their programming environment.

BTW, you do have an amazing client service, it's not the first time I ask question here, and you are always very fast and kind!
I think it worth saying it!!!

I've tested the trial version of Spire.PDF pack and am pleasantly surprised with how easy it was to implement in my project. This is a sharp contrast to other solutions that I've evaluated; please let your IT department know that they're doing a great job.
So far in my testing, Spire.PDF seems to fit the requirements I have, and I have made the recommendation to my boss that this is the pdf library we need.

Mr. McKnight DisplaySoft2016-09-29

I have been evaluating .Doc and .PDF components you have available and they are excellent I have been able to do everything I need. I am so impressed.
I have tried other PDF tools (****) and they don't provide the functionality in which you offer.

Free Spire.PDFViewer for .NET is just the product I was looking for.
Easy to install and it delivers exactly what it promises.
