Thread: Help Needed C# - Need to display Hexadecimal in a textbox

This is the code im using and it displays text in a text box

Code:

Code:

private void sport_DataReceived(object sender, SerialDataReceivedEventArgs e) 
{
DateTime dt = DateTime.Now;
String dtn = dt.ToShortTimeString();


txtReceive.AppendText("["+dtn+"] "+"Received: "+sport.ReadExisting()+"\n");
}

I need it to display Hexadecimal like below

F2,9E,1,0,79,0,0,0,B0,0,0,40,1,7,7,1,A4,3,1D,0,0,0 ,0,3,FF,1,

Have a look here, 2. answer:
c# - Converting string value to hex decimal - Stack Overflow

I have tried that and getting this error

System.FormatException: 'Input string was not in a correct format.'

Ok so now with a little bit of research apparently the data coming out of the ALDL cable is in bytes

Code:

public string ConvertBytes(Byte[] data)
{
   string result = "";
   foreach (var datum in data)
   {
      result += String.Format("{0:X2},", datum);
   }
   return result;
}

how do i implement that into my existing code..... Sorry im still new to this

here is the code im using

Code:

using System;
using System.IO.Ports;
using System.Windows.Forms;






namespace SerialPort
{
    public partial class Form1 : Form

            foreach (String s in System.IO.Ports.SerialPort.GetPortNames()) 
            {
                txtPort.Items.Add(s);
            }
        }

            String dtn = dt.ToShortTimeString();






            sport = new System.IO.Ports.SerialPort(
            port, baudrate, parity, databits, stopbits);
            try
            {

                cmdClose.Enabled = true;
                cmdConnect.Enabled = false;
                txtReceive.AppendText("[" + dtn + "] " + "Connected\n");
                sport.DataReceived += new SerialDataReceivedEventHandler(sport_DataReceived);

You could try

Byte[] bytes = System.Text.Encoding.ASCII.GetBytes(datareceived);
string hex = ConvertBytes(bytes);

datarecieved is the string that sport.ReadExisting() returned. That line makes the string into the type that ConvertBytes() likes, so then you would just pass it.

I'm only assuming that ASCII is the encoding - please use the right encoding.

ok im using this code below

Code:

  private void sport_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            DateTime dt = DateTime.Now;
            String dtn = dt.ToShortTimeString();


            int dataLength = sport.BytesToRead;
            byte[] dataRecevied = new byte[dataLength];
            int nbytes = sport.Read(dataRecevied, 0, dataLength);
            if (nbytes == 0) return;


            string data = BitConverter.ToString(dataRecevied);






            textBox1.AppendText("[" + dtn + "] " + "Received: " + data + "\n");


            // Not Used !!!!!!!
           // txtReceive.AppendText("[" + dtn + "] " + "Received: " + result + "\n");




        }

im getting the hex data i want but i have a dash between the numbers like this

2C-30-30-2C-32-44-2C-32-44-2C-32-44-2C-32-44-2C-32-44-2C-32-44-2C-32-44-2C-32-44-2C-32-44-2C-32-44-0D-0A


how can i remove the dash and replace with a comma like this

F2,70,28,09,01,00,00,07,D4,01,14,6E,6E,6E,6E,6E,00 ,58,00,2D,2D,2D,2D,2D,2D,2D,2D,2D,2D

Code:

byte[] dataRecevied = new byte[dataLength];
int nbytes = sport.Read(dataRecevied, 0, dataLength);
string hex = ConvertBytes(dataRecevied);

Simple enough.

ok i have it working so far

now next thing i need to do is

separate a spring


I need to extract all the different colour sections and put them into variables so i can display them as textnow next thing i need to do is

separate a spring

F2,98,1,4,5,7E,79,37,C,0,0,0,0,1,0,0,0,0,0,4,6B,48,17,F4,0,C8,0,0,FF,C0,3C,0,5,3,0,0,0,5,DC,0,0,0,0, 0,1,50,79,7C,7E,7E,7E,4,0,60,80,78,5,40,80,C0,FF,5,5A,64,5A,5,4,1C,2
