Hi,
I have a client as well as a server.I want to send .csv file to server line by line.I can do read the file line by line and write to the socket.But the problem is that server not receiving data line by line.it accept data after total reading of client's file.
I want client read a LINE and send it to server and server read that line.Again client read next line and send to server.
Any help???????
My client code like this....

client.h
Qt Code: 
  1. class Client : public QObject
  2. {
  3.     Q_OBJECT
  4.     public:
  5.       Client(QObject* parent = 0);
  6.       ~Client();
  7.       void start(QString address, quint16 port);
  8.      // void Read(QString filename);
  9.  
  10.     public slots:
  11.       void readData();
  12.       void sendData();
  13.     private:
  14.       QTcpSocket client;
  15.       QString line;
  16.      char *c_str2;
  17.  
  18.       int LENGTH;
  19. };
  20.  
  21.  
  22. #endif // CLIENT_H
