[QUOTE="Permudious, post: 462676, member: 55273"] Thanks! let me try TcpClient.Connect. It's always a local machine. [automerge]1594793488[/automerge] Okay it's kinda working for now.. only I have an if, else if, else case which checks a value if the value is < 10 than the message is -green if the value = 10 than the message is -red. The value can be changed when the timer is ticking. So I assume that I need to close the tcp connect first before I can open it again. I have tried that but that isn't working. [CODE=csharp]if (TotalIn <= 10) { var client = new TcpClient(); var hostname = "127.0.0.1"; client.Connect(hostname, 4000); NetworkStream networkStream = client.GetStream(); networkStream.ReadTimeout = 5; var writer = new StreamWriter(networkStream); var message = "-green"; var reader = new StreamReader(networkStream, Encoding.UTF8); byte[] bytes = Encoding.UTF8.GetBytes(message); networkStream.Write(bytes, 0, bytes.Length); client.Close(); } else if (TotalIn == 1) { var client = new TcpClient(); var hostname = "127.0.0.1"; client.Connect(hostname, 4000); NetworkStream networkStream = client.GetStream(); networkStream.ReadTimeout = 5; var writer = new StreamWriter(networkStream); var message = "-red"; var reader = new StreamReader(networkStream, Encoding.UTF8); byte[] bytes = Encoding.UTF8.GetBytes(message); networkStream.Write(bytes, 0, bytes.Length); client.Close(); } else { // no message } [/CODE] Whatever I do, the message will always send -green but the value is now 10, so it should be -red.
