Binary files and conversion

[wysota]

How would you recommend to read the file?

With QFile and its QIODevice API.

What I understand is that you simply want a hex dump of the file. The most trivial approach (albeit far from optimal in terms of memory) is:

QFile in("infile");
QFile out("outfile");
in.open(QIODevice::ReadOnly);
out.open(QIODevice::WriteOnly);
out.write(in.readAll().toHex());

QFile in("infile");
QFile out("outfile");
in.open(QIODevice::ReadOnly);
out.open(QIODevice::WriteOnly);
out.write(in.readAll().toHex());

To copy to clipboard, switch view to plain text mode 

You can do the same if you want a decimal encoding, only that you need to iterate over each byte in the array and convert it manually to a decimal value.
