    Question bit by bit -> Binary File Reader

    Good Day,

    I have a binary field, that I need to read bit by bit
    Is there a way to read in the actual binary values of a file.

    I got this so far, but it reads per byte(quint8)

    Qt Code:
    1. QDataStream in(&fileLoadBinary);
    2. int fileSize = fileLoadBinary.size();
    3. int i = 0;
    4. QStringList strngLst;
    5. quint8 tempVariable;
    6. while(i < fileSize)
    7. {
    8. in >> tempVariable;
    9. qDebug() << tempVariable;
    10. strngLst.append(QString(tempVariable));
    11. i++;
    12. }
    13. qDebug() << strngLst;
    To copy to clipboard, switch view to plain text mode 

    I want the actual binary values of the file(bit by bit)
    Whats the way forward?

    Help is much appreciated
    Kind Regards

    You can't read less than a byte each time.(at least, not to my knowledge)
    But why would you need a bit by bit read?
    I am sure the reason will turn out to be not valid.

    Do you write clean code? - if you are TDD'ing then maybe, if not, your not writing clean code.

    No way forward. The smallest amount of data you can access is a byte. Reading bit by bit isn't possible. Make a "buffered input stream" that reads byte by byte then process the read data bit by bit.

    QDataStream is not a general purpose binary stream, it is a serialization mechanism which expects additional data in the stream when reading from that stream. Use QFile::read() instead.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
