It looks like that there is a problem in EasyOPCDA type library (not in the Bonus Pack); introduced in recent builds. It has to do with the fact that _IEasyDAClientEvents does not inherit from IUnknown. Thanks for pointing it out.
I will fix it, post a new build, and notify you here.
Best regards,
Zbynek Zahradnik

Cannot build EasyOPCDADemo example was created by gtSasha
I am having trouble building provided C++ example in VS2008.
When I try to build either 'DumpAddressSpace' or 'EasyOPCDADemo' projects from the bonus pack I get the following error:
error C2664: '_com_issue_errorex' : cannot convert parameter 2 from 'EasyOpcDALib::_IEasyDAClientEvents *const ' to 'IUnknown *'
The error occurs in the generated eopcdat.tli file. What can I do to fix the situation?

Thanks.
