system.net.sockets.socketexception(0x80004005)
no connection could be made because the target machine actively refused it 192.168.1.7:1024
i need to know what is the problem and how can solve
i try to ping that 192.168.1.7 (this access point take ip through tcp/ ip module )and that replay no problem
// Create a TcpClient. // Note, for this client to work you need to have a TcpServer // connected to the same address as specified by the server, port // combination. int port = 1024 ; TcpClient client = new TcpClient(server, port); // Translate the passed message into ASCII and store it as a Byte array. Byte[] data = System.Text.Encoding.ASCII.GetBytes(message); // Get a client stream for reading and writing. // Stream stream = client.GetStream(); NetworkStream stream = client.GetStream(); // Send the message to the connected TcpServer. stream.Write(data, 0 , data.Length); System.Windows.Forms.MessageBox.Show( " Sent: {0}" + message); ; // Receive the TcpServer.response. // Buffer to store the response bytes. data = new Byte[256]; // String to store the response ASCII representation. String responseData = String .Empty; // Read the first batch of the TcpServer response bytes. Int32 bytes = stream.Read(data, 0 , data.Length); responseData = System.Text.Encoding.ASCII.GetString(data, 0 , bytes); System.Windows.Forms.MessageBox.Show( " recieved: {0}" + responseData); // Close everything. // stream.Close(); // client.Close(); catch (ArgumentNullException e) System.Windows.Forms.MessageBox.Show( " ArgumentNullException: {0}" + e); catch (SocketException e) System.Windows.Forms.MessageBox.Show( " SocketException: {0}" + e); System.Windows.Forms.MessageBox.Show( " \n Press Enter to continue..." ); Console.Read(); According to exception - no service listens on this port at this host.
You can check if this port is open using telnet program
telnet 192 . 168 . 1 . 7 1024
To resolve - ensure, that on host some application listens to this port.
