I'm trying to open file and write some text data into it. 

QFile out(":/test.txt");
if (!out.open(QIODevice::ReadWrite)) {
    QMessageBox msgBox;
    msgBox.setText(out.errorString());
    msgBox.exec();
    return;
}

But it fails with "Unknown error". (Qt 4.6, Wnidows XP SP3)

":/test.txt" is a name of a resource file embedded to the executable and you can't write to it. Change the file name for example to "C:/test.txt".

You need to change your QFile constructor argument

QFile out(":/test.txt");

to a correct path that could be

QFile out("./test.txt");

or

QFile out("C:/test.txt");
