      array strings

      What do you mean by this? Please explain better what you want to achieve.
      To display a string you can use QLabel.
      To add an entry to QComboBox use http://doc.qt.io/qt-5/qcombobox.html#addItem

          Are you talking about Json?

              @Vineela If the server sends Json then you have to deal with Json. I gave you a link to documentation for accessing Json data using Qt, you wrote you didn't read it. Now it is time to read that documentation.

                  @Vineela Did you read the documentation?

                  AByteArray data = "YOUR JSON DATA";
                  QJsonDocument doc = QJsonDocument::fromJson(data);
                  QJsonArray array = doc.array();
                  QJsonObject object = array.at(0).toObject();
                  QString code = object["LeaderCode"].toString();
                  

                  To add to QComboBox please refer to the documentation: http://doc.qt.io/qt-5/qcombobox.html#insertItem

                      @Vineela First, you need to make sure you parsed Json correctly. The code I posted does not do that!
                      Then please show your current code (reading Json and putting entries into combo box).
                      One more question: are you sure you actually got the reply from server with Json?

                          @Vineela Your Json string is invalid as it contains <pre></pre>. You need to remove these HTML tags first.

                          data = data.replace("<pre>", "").replace("</pre>", "");
                          QJsonDocument doc = QJsonDocument::fromJson(data);
                          QJsonArray array = doc.array();

                              @Vineela Come on! If you get GNL0001 via array.at(0) then you get GNL0002 via array.at(1)...

                                    @jsulm well I've added this
                                    for(int i=0 ;i<array.size();i++){
                                    QJsonObject object = array.at(i).toObject();
                                    } it worked

                                        Yes, if you do this in a loop then you need to use index (i in your case) instead of fix numbers.
