Problem with writing files on device

[immicro]

I successfully save text to external file with this code, but it works only on Nokia QT SDK emulator. On device I receive just empty video.ram file.

    QString video; // video url string
    QTextCodec *codec = QTextCodec::codecForName("UTF-8");
    QByteArray data = codec->fromUnicode(video);
    
    const char* videoUrl = data.constData();

    QFile *file = new QFile("e://video.ram");
    if (file->open(QIODevice::WriteOnly)) {
    QTextStream out(file);

    out << videoUrl;
    file->close();

Note:I set the permission writeUserData in .pro file

Please advice!


Thanks

Does the device have a volume e, not f?

Check in file manager.

[immicro]

Yes mass storage is e volume, and what is strange when I put 'manualy' for example:

out << "rtsp://v3.cache7.c.youtube.com/CjYLENy73wIaLQnHdoOcHgUFfBMYESARFEIJbXYtZ29vZ2xlSARSBXdhdGNoYLbi-pqEivrSTQw=/0/0/0/video.3gp";

everything is ok.

I'm puzzled by this.

I use qt4.6 and E7 Nokia device.

1. make sure codec->fromUnicode(video); returning something by checking size of QByteArray data and
2. try out << QString(data);

Yes I checked just getting empty data array on device. How to solve this?

so the problem is not in writing on the device then QTextCodec *codec = QTextCodec::codecForName("UTF-8");


i suggest you create another ticket for this.

Hi immicro,
According to your code QString video is empty... is that the cause which lead you to have an empty file?

Moreover, I've seen you are playing with codecs instead of using QString methods.
What about using something like this??

out << QString::fromUtf8(charsArrayBuffer);

[immicro]

Yes you are right, I found error elsewhere in the code, is not related to writing to device. Sorry...
