Re: [boost] Help with Access Violation in simple serialization

Here is how I managed not to correct, but to work around my bug:

[code]

    stringstream archbuf;
    boost::archive::text_oarchive *oa = new
boost::archive::text_oarchive(archbuf, 3 );

    const structs::POINT2D aaa = {1,2,3,4};
    const structs::LIVE_CAM aaumalivec = {5, 6, 7, 8, 9};
    const structs::POINT2D_PAIR aappp = {10, 11, 12, 13,  14, 15, 16, 17};

    const string anana = "ana acaxa kkk";

    *oa << aaa;
    *oa << aaumalivec;
    *oa << anana;
    *oa << aappp;

    std::cout << "-- archive content: >" << archbuf.str() << endl;

//    archbuf.flush();

    ofstream ofs("savedProject.imag3d");

    ofs << archbuf.str();

    ofs.close();

    delete oa;

[/code]

basically, I use boost to serialize everything inside a stringbuffer, and
then I write the whole string buffer to a file.
