c++ - Sending data through socket spaces, receiving with spaces -


i'm using c++ qt4 this. , when try send large html files(in case, 8kb), process of sending , receiving work well. file received come spaces between each character of html file. here example, file sent 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, this:

  ¼ < ! d o c t y p e   h t m l   p u b l 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 c t . d t d " >   < h t m l > < h e d > < m e t   n m e = " q r c h t e x t "   c o n t e n t = " 1 "   / > < s t y l e   t y p e = " t e x t / c s s " >   p ,   l   {   w h t e - s p c e :   p r e - w r p ;   }   < / s t y l e > < / h e d > < b o d y   s t y l e = "   f o n t - f m l y : ' m s   s h e l l   d l g   2 ' ;   f o n t - s z e : 8 . 2 5 p t ;   f o n t - w e g h t : 4 0 0 ;   f o n t - s t y l e : n o r m l ; " >   < p   s t y l e = " - q t - p r g r p h - t y p e : e m p t y ;   m r g n - t o p : 0 p x ;   m r g n - b o t t o m : 0 p x ;   m r g n - l e f t : 0 p x ;   m r g n - r g h t : 0 p x ;   - q t - b l o c k - n d e n t : 0 ;   t e x t - n d e n t : 0 p x ; " > < / p > < / b o d y > < / h t m l >

the code i'm using sending , receiving:

sending code: qdebug() << "connected. sending file 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 = 0; < 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 bet there not spaces between characters (but 0s) & chars due use of quint16.
