Hi, Following program does not pertain a proper "other" value: #include <iostream> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/ini_parser.hpp> using namespace std; using boost::property_tree::ptree; int main() { ptree pt; pt.put("debug.filename", "tst.log"); pt.put("other", "tst"); cout << "debug.filename: " << pt.get("debug.filename", "filename not found") << endl << "other: " << pt.get("other", "other not found") << endl; boost::property_tree::write_ini("tst.ini", pt); boost::property_tree::read_ini("tst.ini", pt); cout << "debug.filename: " << pt.get("debug.filename", "filename not found") << endl << "other: " << pt.get("other", "other not found") << endl; return EXIT_SUCCESS; } The ini file contains: [debug] filename=tst.log other=tst Do I do anything wrong or is that a bug? Thanks for help or suggestions, -- Bernd
