Re: [Boost-users] [Serialization] Loading from archive

eliminate the stream close() statements. The sequence is construct stream construct archive ar << ... destroy archive - for xml at least this finishes off the xml. destroy stream - this empties the buffer and closes the stream There is another more fundamental problem with your code: Robert Ramey Sam Contapay wrote:

----------ORIGINAL EMAIL---------------- I've been trying to get loading from an archive to work for a couple of hours now. Maybe I'm missing something so I can use anyones "eyes" for help. This is a program written using VC7.1 and I do have RTTI on. I am able to save data from a MAP file to an ASCII text file using the serialize functions, but I'm having a problem getting that information back into my object. Here are some relevant code snippets if anyone can point me in the right direction it would be really appreciated. Also is their an archive that I can search? This news group is only leting me download like 100 messages.

main class with serialize

private: std::map WordMapA; std::map WordMapB; friend class boost::serialization::access; template <class Archive> void serialize(Archive & ar, const unsigned int version) { ar & WordMapA; ar & WordMapB; }

Now here is my save and load

save: // Save the bayes filter especially the map for later use std::ofstream ofs("BayesFilter.stb"); boost::archive::text_oarchive outarchive(ofs); outarchive << this; ofs.close();

load:

std::ifstream ifs("BayesFilter.stb"); boost::archive::text_iarchive ia(ifs); CObjTest test; ia >> test; ifs.close();

When I save the file it saves to an ASCII file with no problems. When I then try to load the archive back all the Map data variables are still 0 after a call to the load function. I poured over the demo and its pretty much word for word so I don't know whats wrong any help... thanks.
