Developing C# Windows Form to See Flight Parameters

[Emre Alan]

Hello everyone

I wrote a very simple Windows Form program that can display flight parameters on a second computer connected to the same wired network.

I also wrote a mode that sends data to this windows form via KSP.

KSP Plug-in

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using UnityEngine;
using System.Net;
using System.Net.Sockets;

namespace KSP_Connect
{

    [KSPAddon(KSPAddon.Startup.Flight, false)]

    public class VeriAktarimi : MonoBehaviour
        
    {

        private const int port = 1234;
        private const string serverIP = "192.168.0.108"; // Receiver IP

        public void Update()

        {

            
            Double Altitude = Math.Round(FlightGlobals.ActiveVessel.altitude,2);

            Double RadarAltitude = Math.Round(FlightGlobals.ActiveVessel.radarAltitude,2);
            
            Double SpeedVector = Math.Round(FlightGlobals.ActiveVessel.speed,2);

            Double SurfaceSpeed = Math.Round(FlightGlobals.ActiveVessel.srfSpeed, 2);

            Double VerticalSpeed = Math.Round(FlightGlobals.ActiveVessel.verticalSpeed, 2);

            Double OrbitalSpeed = Math.Round(FlightGlobals.ActiveVessel.obt_speed);

            
       

            using (TcpClient client = new TcpClient(serverIP, port))
            using (NetworkStream stream = client.GetStream())
            {
                string data = Altitude + ":" + RadarAltitude + ":" + SpeedVector + ":" + SurfaceSpeed + ":" + VerticalSpeed
                    +":"+OrbitalSpeed;
                
                byte[] buffer = Encoding.ASCII.GetBytes(data);
                stream.Write(buffer, 0, buffer.Length);
            }
        
                
        }
        
    }
}

 

Codes of the receiver windows form and the visual of receiver:

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Seri_Iletisim_Alici
{
    public partial class Form1 : Form
    {

        private const int port = 1234;
        private TcpListener listener;



        public Form1()
        {
            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }


        private void StartListening()
        {
            try
            {
                while (true)
                {
                    TcpClient client = listener.AcceptTcpClient();
                    HandleClient(client);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("Error: " + ex.Message);
            }
        }


        private void HandleClient(TcpClient client)
        {
            try
            {
                NetworkStream stream = client.GetStream();
                byte[] buffer = new byte[1024];
                int bytesRead = stream.Read(buffer, 0, buffer.Length);
                string data = Encoding.ASCII.GetString(buffer, 0, bytesRead);
                string[] parts = data.Split(':');
                UpdateLabels(parts[0], parts[1],parts[2],parts[3],parts[4],parts[5]);
                client.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show("Error: " + ex.Message);
            }
        }


        private void UpdateLabels(string value1, string value2,string value3,string value4,string value5, string value6)
        {
            if (label1.InvokeRequired || label2.InvokeRequired )
            {
                Invoke(new MethodInvoker(() => UpdateLabels(value1, value2, value3, value4, value5, value6)));
            }
            else
            {
                lblAltitude.Text = value1;
                lblRadarAltitude.Text = value2;
                lblSpeed.Text = value3;
                lblSurfaceSpeed.Text = value4;
                lblVerticalSpeed.Text = value5;
                lblOrbitalSpeed.Text = value6;
                
            }

        }


        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                listener = new TcpListener(IPAddress.Any, port);
                listener.Start();
                MessageBox.Show("Server started successfully!");
                Task.Run(() => StartListening());
            }
            catch (Exception ex)
            {
                MessageBox.Show("Error starting server: " + ex.Message);
            }

        }


    }

}

 

The codes and program-plug-in are working normally.

However, I cannot access other parameters of the flight. For example, Throttle Rate, apoapsis and periapsis etc.

How can I access these parameters?
