serialization library problems with MFC support for OLE ControlsWell, its difficult address problems generated by the compiler. However, you might be able to keep serialization headers and Mfc/ole headers out if the same module using the technique shown in the PIMPL example. This would ameliorate this problem, make your application more robust and improve re-build times.

I had problems using boost serialization library classes with MFC support for OLE controls. This is what I have, #include <afxctl.h> // MFC support for OLE Controls #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> ............. .............. When I compiled the code I got errors like, :\boost\boost-1_32\boost/archive/basic_text_iprimitive.hpp(72) : error C2039: 'char_type' : is not a member of 'IStream' D:\Devstudio_6.0\VC98\INCLUDE\objidl.h(4049) : see declaration of 'IStream' D:\boost\boost-1_32\boost/archive/basic_text_iprimitive.hpp(121) : see reference to class template instantiation 'boost::archive::basic_text_iprimitive<IStream>' being compiled D:\boost\boost-1_32\boost/archive/basic_text_iprimitive.hpp(72) : error C2065: 'char_type' : undeclared identifier D:\boost\boost-1_32\boost/archive/basic_text_iprimitive.hpp(121) : see reference to class template instantiation 'boost::archive::basic_text_iprimitive<IStream>' being compiled D:\boost\boost-1_32\boost/archive/basic_text_iprimitive.hpp(73) : error C2039: 'traits_type' : is not a member of 'IStream' D:\Devstudio_6.0\VC98\INCLUDE\objidl.h(4049) : see declaration of 'IStream' I think, error is because MFC has class called IStream. And the same name IStream is used as template parameter in the boost class. Is there anything I can do to overcome this problem. annamalai _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
