I know this is a very basic question but I'm newbie in Qt and I don't know to do it. I'm trying to convert a QString value (like "AA110011") to hexadecimal. I would like to obtain 0xaa110011. I've tried with this code:

QByteArray b = aString.toUtf8();

for (int i = 0; i < b.length(); i++ )
{
    if ( b[i] >= 65 && b[i] <= 70 )
    {
        b[i] = b[i] - 55;
    }
    else if (b[i] >= 48 && b[i] <= 57)
    {
        b[i] = b[i] - 48;
    }
}

I obtain in the Memory at Vairable "[0]" the value 0a 0a 01 01 00 00 01 01 and I don't know how could I obtain aa 11 00 11.

Could you help me? thanks.
