I have a xml file setting app.. (portable) and i load this file to..

Code:

typedef QMap<QString, QString> Appsetting;
 
Appsetting OneVar;
 
      QStringList varioarg;
      varioarg.clear();
      QString variablelist = Global_Config_Base("allname",APPLICATION_SETTING);
      varioarg = variablelist.split("|");
	 QStringListIterator o(varioarg);
                    while (o.hasNext()) {
                        QString variablename = o.next();
                        QString valorsi = Global_Config_Base(variablename,APPLICATION_SETTING);
                        OneVar[variablename] = valorsi;
                        qDebug() << "### variablename    " << variablename << " = " << OneVar[variablename];
                    }
     /* usage from 2 dbs ? */
     if (OneVar["usedb2"] == "1") {
	 usedb2 = true;
	 } else {
