Thank you so much for the information and the hotfix of Spire.Doc!
I just tested the hotfix and all issues seem to be resolved. I am very happy that your developers were able to solve these layout problems (to be honest, I didn't expect the problems could be solved).

Peter S.Noerr

Our group was looking for a cost-effective way to add reliable barcode generation to our web application. We tried some free ones that we found to be inaccurate and put our customers at risk.
Spire.Barcode for .Net has proven to pass our test cases as well as come with a free license. Couldn't be happier!

Eric BrownChildrenSAL

I'm waiting for a confirmation from my superiors to buy the license. But we already finished the tests with the Spire.Doc, and it works perfectly!
We are very excited to start to work with it, because it fixes a lot of bugs that we have using the Microsoft.Office.Interop's dll.
I guess that I'll probably have the confirmation in the begin of the next year.
