Hello, I have 2 questions regarding the Serialization library: ========================= I have a function that I am using to load a serialized class, called "Configuration". A particular line in the function produces a warning message. Should I be worried about this warning? The function is below, with a comment denoting the warning-producing line. void Configuration::Save(const string& Name) { ofstream Out(Name.c_str()); if(Out.fail()) throw runtime_error("Error: unable to save configuration file."); boost::archive::text_oarchive Archiver(Out); Archiver << *this; // This line produces the warning. } The warning is: C4308: negative integral constant converted to unsigned type ... error is from file: \boost\mpl\print.hpp line: 51 ========================= In a separate question, I'm wondering why this code compiles: template<class Archive> void save(Archive& ar, const boost::asio::ip::udp::endpoint& endpoint, unsigned int version) { unsigned short Port = endpoint.port(); ar << endpoint.address().to_string(); ar << Port; } But this code does not compile: template<class Archive> void save(Archive& ar, const boost::asio::ip::udp::endpoint& endpoint, unsigned int version) { ar << endpoint.address().to_string(); ar << endpoint.port(); } The only difference is endpoint.port() is stored in a seperate unsigned short. ========================= Any help is much appreciated! -- Dylan
