Hi Ludek,
A few follow up questions as follows:
1) Your "apartment model" means setting the ApartmentState.MTA for the threads (not STA), am I right?
2) I found your refered document "SAP Crystal Reports Engine in a Multi-Threaded Visual Studio Application" is talking about the CR2008, it can also be applied in CR2011, am I right?
3) We got some old projects using CR XI (C++ API), may I know, are they able to use multiple for generating the reports to PDF?
Thanks in advance.
Cheers,
Elliott
