cannot read correct len from socket

[saman_artorious]

If you are writing "47Saman" to the socket, what do you expect to receive as first four bytes on the other end of the communication?

Wysota, client is sending me a jpeg file. in the server program, I used readAll() to read it all and pixmap it to a label. But, the image does not appear in the label (though the widget background flashes). To solve this, I was told that they would send the size of the jpeg file along with its content. Hence, I need to read the length first, and then realize how many bytes exactly to read.

void MainWindow::readPixmap(QByteArray data)
{
    QPixmap pm;
 
    pm.loadFromData(data);
 
    ui->label->setPixmap(pm);
}

void MainWindow::readPixmap(QByteArray data)
{
    QPixmap pm;

    pm.loadFromData(data);

    ui->label->setPixmap(pm);
}
