We are using 3rd Party ActiveX Control - ASPPDF - www.asppdf.com
- to print to PDF from our ASP.Net web site. We have two different web sites that are using this ActiveX Control. These two web sites are running in Client Production Server for past 5 years.
Client have two mirrored IIS production Servers, both have hosted these two sites.
When we recently updated one of the website in Client Production, a strange isssue happened!
The site that I updated in Production (say Site1) is working with ASPPDF perfectly. But the other site (say Site2) which is hosted on the same server that is using ASPPDF, crashes on Print to ASPPDF.
Site 1 is working in Server 1, but crashes in Server 2
Site 1 is crashes in Server 1, but working in Server 2
Both have the same version of source codes.
Error Message:- Object reference not set to an instance of an object
Previously whenever this crash occurs the reinstallation of ASPPDF will fix this crash - which means this crash is due to something wrong happens with the registration of this ActiveX Control.
I tried re-install ASPPDF - Not helped this time!
I hope this is clear.
Could you please give me some idea, how to fix it ;( - Please Urgent
Any help would be highly appreciated
