Well I might made a mistake, I am kind of a amatuer programmer but on the
real code, the problem is also same. I mean after I read stream to string,
string is empty.
But for now it is working. Like you and others pointed, the problem was I
was reading different size of bytes.

I approach to QByteArray like std::string.

Ah can you be more specific please? Because I have just cheated from qt-docs
<http://doc.qt.io/qt-5/qdatastream.html#details> writing to and reading
from a file if you are talking about constructing a QDataStream from a
QFile.

Cheers,
Sina
