Hello everybody,
i have a strange pbm here. I have QTcpServer Which do listening accepting new connections putting data on dialog level. I have fortune client type code which transfers the data to server.
I have few problems here.Major problem is QTcpServer is not reading as fastly as client is writing.

code for server is
Qt Code: 
  1. void MyDialog::settingServer()
  2. {
  3. 	tcpServer=new QTcpServer(this);
  4. 	if(!(tcpServer->listen(QHostAddress::Any,35000)))
  5. 	{	cout<<"\n Tcp Server not listening";
  6. 		QMessageBox::critical(this,tr("server"),tr(" not able to start"));
  7. 	}
  8. 	else
  9. 	{
  10. 		int x=tcpServer->serverPort();	
  11. 		label->setText(QString("Server is listening on port ")+QByteArray::number(x));
  12. 		connect(tcpServer,SIGNAL(newConnection()),this,SLOT(activatingNewConnection()));
  13. 	}
  14. }
  15.  
  16. MyDialog::~MyDialog()
  17. {
  18.  
  19. }
  20.  
  21. void MyDialog::activatingNewConnection()
  22. {
  23. 	tcpSocket=tcpServer->nextPendingConnection();
  24. 	connect(tcpSocket, SIGNAL(disconnected()),tcpSocket, SLOT(deleteLater()));
  25. 	connect(tcpSocket,SIGNAL(readyRead()),this,SLOT(dataAvailable()));
  26.  
  27.  
  28. }
  29.  
  30. void MyDialog::dataAvailable()
  31. {
  32.  
  33. 	QDataStream in(tcpSocket);
  34. 	in.setVersion(QDataStream::Qt_4_0);
  35. 	if(tcpSocket->bytesAvailable() <= 0 )
  36. 	{
  37. 		//cout<<"\nNothing	Available for reading";
  38. 		return;
  39. 	}
  40. 	QString st;bool ok;
  41. 	int i;
  42. 	in >> st;
  43. 		label->setText(st);
  44.  
  45. }

important code for client is
Qt Code: 
  1. void Client::sendingData(int x,int y)
  2. {
  3. 	QByteArray block;
  4. 	QDataStream stream(&block,QIODevice::ReadWrite);
  5. 	stream.setVersion(QDataStream::Qt_4_0);
  6. 	QString temp;
  7.  
  8. 	temp = QString( QString(QByteArray::number(x)));
  9.  
  10. 	stream.device()->seek(0);
  11. 	stream << temp;
  12. 	cout<<"\n"<<temp.toInt()<<endl;
  13. 	QString st="he;llo world";
  14. 	cout<<st.data()<<endl;
  15. 	if(tcpSocket->write(block)==-1)
  16. 		QMessageBox::critical(this,tr("Socket Warning"),tr("Not able to write to socket"));
  17. 	else
  18. 	{
  19. 		statusLabel->setText(tr("Hi")+QString(QByteArray::number(x))); 
  20.  
  21. 	}
  22.  	temp = QString(QString(QByteArray::number(y)));
  23.  	stream << temp;
  24.  	cout<<temp.toInt();
  25.  	if(tcpSocket->write(block)==-1)
  26.  		QMessageBox::critical(this,tr("Socket Warning"),tr("Not able to write to socket"));
  27.  	else
  28.  	{
  29.  		statusLabel->setText(tr("Hi")+QString(QByteArray::number(y)) );
  30.  
  31.  	}
  32. }

i need guidance on one more issue, Say multiple clients get connected to socket. How i will diffrentiate between the data which i receives from various sockets.
i think above code can cater to multiple clients.
