    Hi,

    Except the possible typo with Serever, did you save it first once ?

                [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. ;)
