    QString has a constructor which takes a QByteArray object as a parameter.
    std::string (because I presume this is the subject of the second question) has a constructor that takes a const char* as a parameter and const char * can be obtained from QByteArray using its data() or constData() methods.

    I need to be able to print the message contained in the QByteArray in the screen. I am not using any GUI, therefore I am using std::cout.

    std::cout << "The msaage in the QByteArray is: " << here should be the message << "\n";

    How ?

    QByteArray::data() or QByteArray::constData(). Could you please read the docs first before asking such questions? This is elementary knowledge and it surely doesn't belong to "Qt programming" forum. Moving to "Newbie".
