Validating license

[Jan.vanSoelen]

The Spire PDF dlls seem to work without applying the license file.
Is this just for a trial period?
If so, how are we able to validate whether the license works after the trial?

Hello,

Thanks for your inquiry. Without applying the license, the dlls work, but there will be an Evaluation warning message at the top of the result file that generated by Spire.Pdf, after applying the license with the following method, the warning message will disappear.

If any doubt, please write back to us.

Thank you for your answer.
At this time the application is not generating PDFs, it just extracts texts from PDFs.
With this limited usage of the Spire PDF functionality Is there anyway to tell whether the license will work?
