[Boost-users] easy serialization question

Hi, I'm using the boost serialization methods, they're great. I'm using some 3rd party classes that I don't have access to, so I can't add a serialize() member function to them. It's something like: class CMyClass { int m_nWhatever; CSomeClass m_sc; // I am just using this from someone else's library.... void serialize(Archive &ar, const unsigned int version) { ar & version; ar & m_nWhatever; ar & m_sc; // fails!!! } } how can I get around this? Thanks, Mark
