Error in Converting Qstring to std::string

[Raminlich]

hi all and this is my code
@{

    QString names;
    ofstream mys("e:/mystock.txt");
    mys.open("e:/mystock");
   names.toStdString();
    mys<<names;
    mys.close();

}
@
when i change "names" variable to string there is no error
but when i change it to qstring and then i want to change it to std string this error will come:

no match for 'operator<<' (operand types are 'std::ofstream {aka std::basic_ofstream<char>}' and 'QString')
mys<<names;
^

Thanks

@
names.toStdString();

[/quote]You need to use the return value of toStdString(). The function returns a copy of your data as a std::string, but it doesn't modify names. names is still a QString.
