    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();
                        QJsonObject object = array.at(0).toObject();
                        QString code = object["LeaderCode"].toString();
                        
                        ui->comboBox_54->insertItem(3,code);

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

                              @jsulm i know but can't i add it within this line
                              QJsonObject object = array.at(0).toObject(); so i have to write another object2

                                  @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.
