I'm facing a problem ... i have made the same application but i keep getting the string from the server 2 times when reading from the client even if i send it only once...... i have got some clue saying that i have to clear socket ..... but how >??

Sounds like a problem of the buffering technique. Check out the example mentioned in my previous post. It uses QBuffer to handle all transmission data.
