Hi everyone:
I have a tcpClient and tcpListener and i want to know how can i recive data from the client to the server and display it in a textbox in the server windows form.

//private TcpClient[] m_Client;
private TcpClient m_Client;
//int count = 0;
private void btnConnect_Click(object sender, EventArgs e)
{
Thread acceptClients = new Thread(new ThreadStart(acceptConnections));
acceptClients.IsBackground = true;
acceptClients.Start();
}

updInfo("listening");
//while (true)
//{
// m_Client[count] = m_Socket.AcceptTcpClient();
// sendData(m_Client[count], "connected");
// updInfo("new client");
// count++;
//}
while (true)
{
m_Client = m_Socket.AcceptTcpClient();
sendData(m_Client, "connected");
updInfo("new client");
}
}
catch (Exception error)
{
updInfo(error.Message);
}
}
