    config_write->setValue("ip/first","192.168.0.1");

    config_write->setValue("ip/second","192.168.0.2");

    config_write->setValue("ip/third","192.168.0.3");

    config_write->setValue("port","8080");

    delete config_write;

    QSettings*config_read=new QSettings("eric.ini",QSettings::IniFormat);

    QString ip_first=config_read->value("ip/first").toString();

    QString ip_second=config_read->value("ip/second").toString();

    quint16 port=config_read->value("port").toInt();
