TCP Client issue

Hello,
I'd like to convert a char array to a string so I can show it in a status label or a text edit box:
Example:

Code:

---

char temp[4] = {0x01, 0x03, 0x03, 0x04};
....
statusLabel->setText(QString::fromAscii(temp, 4));

---

The status label should show ideally 0x01 0x02 0x03 0x04.

I'm trying to do this in the fortune client example from Qt Creator.

Code:

---

void Client::readFortune()
{
    QDataStream in(tcpSocket);
    in.setVersion(QDataStream::Qt_4_3);
 
    char temp[30];
    int flag = 0;
    char temp2[4] = {0x01, 0x02, 0x03, 0x04};
 
    if (blockSize == 0) {
        if (tcpSocket->bytesAvailable() < (int)sizeof(quint16))
            return;
 
        in >> blockSize;
    }
 
    flag = tcpSocket->readLine(temp, 31);// i'm trying to read the receive buffer here and show it below
    if(flag |= -1){
        messageLineEdit->setText(QString::number(blockSize)); // I can see the block size, 1537
        statusLabel->setText(QString::fromAscii(temp2, 4));
    }
 
    if (tcpSocket->bytesAvailable() < blockSize)
        return;
 
    QString nextFortune;
    in >> nextFortune;
 
    if (nextFortune == currentFortune) {
        QTimer::singleShot(0, this, SLOT(requestNewFortune()));
        return;
    }
 
    currentFortune = nextFortune;
 
    statusLabel->setText(currentFortune);
 
    getFortuneButton->setEnabled(true);
}

0x01-0x04 are unprintable characters. What you want is probably this:

Code:

---

char temp[4] = {0x01, 0x03, 0x03, 0x04};
QStringList hex;
for(int i=0;i<4;i++) {
  hex << QString("0x%1").arg((int)temp[i], 2, 16, QLatin1Char('0'));
}
statusLabel->setText(hex.join(" "));

Thank you for your quick answer.
I know I couldn't possibly print it directly, I already developed de server that sends the data to the client and I had to do the same thing but in C.
Anyway, it worked perfectly!


Thank you for your help,
