I’m using C++ with QT4 for this. And when I try to send large html files(in this case, 8kb), the process of sending and receiving work well. But the file received come with spaces between each character of the html file. Here an example, the file is sent like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><style type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style=" font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">a</p></body></html>
and it’s received, like this:
¼ < ! D O C T Y P E H T M L P U B L I C " - / / W 3 C / / D T D H T M L 4 . 0 / / E N " " h t t p : / / w w w . w 3 . o r g / T R / R E C - h t m l 4 0 / s t r i c t . d t d " >

p , l i { w h i t e - s p a c e : p r e - w r a p ; }

the code i’m using for sending and receiving:
Sending code:
qDebug() << "Connected. Sending file to the server"; QString text = ui->QuestHtmlText->toPlainText();
if(text.length() < 1024)
{
QByteArray block;
QDataStream out(&block, QIODevice::WriteOnly);
out << quint16(0) << QUESTION_HTML;
out << text;
out.device()->seek(0);
out << quint16(block.size() - sizeof(quint16));
qDebug() << "Block size: " << block.size();
socket.write(block);
return;
}
for(int i = 0; i < text.length(); i+=1024)
{
QByteArray block;
QDataStream out(&block, QIODevice::WriteOnly);
out << quint16(0) << QUESTION_HTML;
if((text.length() - i) > 1024)
out << text.mid(i, i+1024);
else
out << text.right(1024 - i);
out.device()->seek(0);
out << quint16(block.size() - sizeof(quint16));
qDebug() << "Block size: " << block.size();
socket.write(block);
}
Receiving code:
qDebug() << "Writing File";
QDataStream in(this);
QString temp = "Teste.html", text;
QFile myFile(".//Questions//" + temp);
myFile.open(QIODevice::WriteOnly);
QDataStream out(&myFile);
while(!in.atEnd())
{
in >> text;
out << text;
}
I did opened a post before, here: Sending data through socket spaces, receiving with spaces
People stopped helping me out. By the way, i didnt feel like my question was completly answered. So I opened another post.
I also looked in the FAQ section to see what should I do in this case. But with no sucess.
Anyway, my question now is: should I remove the quint16? what should I use to determine the size of the incoming packet then ?
Thanks, and I’m sorry about the mistakes I may have made.
I posted the solution for my case in the other post.
Thanks you all for the attention
