Code:
QString COneNavQueryBuild::buildArchiveQuery(const QString m_szRecordname,const QString m_zsOperation)
{
    ......................
    ......................
    if(m_zsOperation.startsWith("Ident"))

      ..................................  
       return sQuery;
    }
    else if (m_zsOperation.contains("GeoArea"))
    {
        ................................
        ...............................      
        QString m_szWstr  = lst.at(2);
        double WLongitude = -0.0;
        ..................................
        if(m_zsOperation.startsWith("In GeoArea"))
        {
            sprintf(chBuffer,"(Latitude>=%f And  Latitu
      }
        else
        {
            sprintf(chBuffer,"(Latitude<%f And  Latitude>%f) And (Longitude<%f And Longitude>%f )",
                    -(SLatitude),NLatitude,-(WLongitude),ELongitude);
        }
        sQuery.append(QString(chBuffer));
    }
    else
    {
        sQuery.append(m_zsOperation);
        return sQuery;
