DocuVieware Lite exception

Post by azeeth » Thu May 09, 2019 6:25 am

Hi I had implemented full DocuVieware to display PDFs in Asp.Net web forms application which was working beautifully. But because of licencing I have decided to do with DocuVieware Lite for now.
But since I have turned to Lite version, I am unable to access the page when deployed. I am able to access it when run from Visual Studio. The implementation is still same, only licence has changed to Lite version.

Following exception I get as soon as I try and access the page. I think I have included all the required dlls in bin folder.

Code: Select all

[NullReferenceException: Object reference not set to an instance of an object.]

I am also seeing weird w3wp.exe crashing since the app has been deployed. I enabled tracing, It wasn't much helpful.

Hello,

The DocuVieware Lite version servers like very simple viewer. Some features are unavailable here:
DocuVieware Lite
I'm not sure what you mean by "I am unable to access the page when deployed"? Could you explain more?
Thank you.

ok I was able to fix the issue finally after some head banging. It was to do with the DocuVieware cache folder not having permissions. I had to change its location to be able to load the viewer.
This is something that can be improved in your product I think, there is no appropriate error message in this case.
