Converting to negative int - bug

[ShamusVW]

Thanks for advice, but at the end of the day, I don't know how!
The original issue came up when I was trying to do a MODBUS application, and I got it to work back then by doing what I'm doing now.

Like so...?

m_DataEccentricity[0] = block[21];
m_DataEccentricity[1] = block[22];
m_DataEccentricity[2] = block[23];
m_DataEccentricity[3] = block[24];
QMessageBox box;
box.setText(m_DataEccentricity);
box.exec();

m_DataEccentricity[0] = block[21];
m_DataEccentricity[1] = block[22];
m_DataEccentricity[2] = block[23];
m_DataEccentricity[3] = block[24];
QMessageBox box;
box.setText(m_DataEccentricity);
box.exec();

To copy to clipboard, switch view to plain text mode 

The camera (where we are reading inputs from) has gone down, so no way to test it right now.

Testing

QByteArray ba("\xBD\xC6\xD6\x04");
QMessageBox box;
box.setText(ba);
box.exec();

QByteArray ba("\xBD\xC6\xD6\x04");
QMessageBox box;
box.setText(ba);
box.exec();

To copy to clipboard, switch view to plain text mode 

doesn't work though.
