          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. ;)
