      [quote author="SGaist" date="1398287969"]Where is database.ini located ?[/quote]

      No specific path !

      I can write into this ini file with below code :

      QSettings settings("database.ini", QSettings::IniFormat);
      settings.setValue("Server", "192.168.1.1");

      but for read.... I don't know why doesn't work.

        Just a wild idea:

        try with foo in place of General for the group name

            Before that, just saw something:

            @
            QSettings settings(“database.ini”, QSettings::IniFormat); settings.setValue(“Server”, “192.168.1.1”);
            @

            You don't begin the group, is that a missing line ?

              but this is not for Read from ini file ! I don't have problem with setValue :)
              My main problem is reading from file :(

              You just show me how can I read from ini file , maybe I have a little mistake.
              Of course my ini file content is :

              [General]
              Server=192.168.1.1

              Why I can't read 192.168.1.1 from server!?

                The thing is: your writing to the init file and your reading must match.
                Using :

                @
                QSettings settings(“database.ini”, QSettings::IniFormat); settings.setValue(“Server”, “192.168.1.1”);
                @

                to write, then you must use

                @
                QSettings settings(“database.ini”, QSettings::IniFormat);
                QString server = settings.value(“Server”, “”).toString();
                @

                to read it back

                [edit: corrected my code]

                  No ! error... in QString server = settings.value(“Server”, “”);

                  I changed it to below format with QVariant

                  @
                  QSettings settings("database.ini", QSettings::IniFormat);
                  QVariant server = settings.value("Server", "");

                  qDebug() << "Server = " << server.toString();
                  @

                  Result is :

                  Server = "192.168.1.1"

                  Good work :)
                  Thank you very much. ;)

                    You're welcome !

                    Since you have your settings working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
