Please, provide us with your internal implementation of SendMsg method.

maxpower12345 1-Jun-12 16:32pm

public void SendMsg(TcpClient myclient, string msg)
{

NetworkStream clientStream = myclient.GetStream();
ASCIIEncoding encoder = new ASCIIEncoding();
byte[] buffer = encoder.GetBytes(msg);

clientStream.Write(buffer, 0, buffer.Length);
clientStream.Flush();

}

For normal Client/Server development, the server has a listening socket waiting for clients to connect. The clients initiates the connection and messages are exchanged.
Have you made an implementation where both the client and the server have listening sockets? If that is the case, you might have good reasons for that, just make sure both of them don't listen on the same port.

its different port
its just give me this error
No connection could be made because the target machine actively refused it 127.0.1.6:5050

What makes you thinking that is should accept the connection? What do you run on the other side? Do you in fact know that?

That IP address does not look right. 127 addresses refer to the local machine.

What's wrong? Nothing is right. Please pay attention for the comment by SoMad. Probably, your idea on how it's working has little to do with reality...

Hello

Look at this:

Sharing data among Windows Forms.
Especially this part: "Is there a way to send a message back to the server from the client?"
