Reading an HEX file and store into a QByteArray

Hello,

I have an issue when I try to read an HEX document and store the content into a QByteArray. What I want to get is a QByteArray with HEX content and show the content in a LineEdit.

I works for almost perfect but is not working when one byte is "0x0d" (\r). ¿Which is the correct conversion type when reading the file to an HEX QByteArray?

Code:

---

QFile file(ui->lineEdit_FilePath->text().toLatin1());
 
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
            return;
 
ui->lineEditSize->setText(QString::number(file.size()));
 
QTextStream fileTextStream(&file);
 
QByteArray contentHex = fileTextStream.readAll().toLocal8Bit());
 
ui->lineEdit_1->setText(contentHex.mid(0,4).toHex());

---

I also tried doing this:

Code:

---

QString content = fileTextStream.readAll();
QByteArray contentHex = content.toLatin1().toHex();

---

In this case I had a problem when reading values upper than 0x7f but I solved it using ".toLocal8Bit()" but now the problem is with "0x0d" byte values.



Thanks in advance.

You have to use QFile not QTextStream.

Thanks,

I removed the QTextStream and also I had to change this line to work:

Code:

---

if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
            return;

---

To this:

Code:

---

if (!file.open(QIODevice::ReadOnly))
            return;

---

Thanks a lot!
