I'm using visual studio to create a program in C# with Kmotion_dotNet.

My problem is at the moment of handling exceptions, because only occurs once

is there a flag a need to clear?

for example when I send a comand via :

    void SendCommand()

    {

            try
            {
                KM.WriteLine(s);
            }
            catch (DMException) // in case disconnect in the middle of reading status
            {
                MessageBox.Show(ex.InnerException.Message);
            }

    }

and I don't have a kflop connected it show the message

but if I try a second time the message it's not displayed

I'm usign KMotion 4.33 and visual studio 2015 I also attached the project.

I created a simple form that only jog the X axis


if I press one of the buttons without the KFlop Plugged I get an error :



but if I click the button again this error doesn't show anymore, like the code is not allowed to throw an exception.

Below it's the code I'm using:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using KMotion_dotNet;

namespace Error_Test
{
    public partial class Form1 : Form
    {
        KM_Controller KM = new KM_Controller();
        public Form1()
        {
            InitializeComponent();
           
        }

        private void btn_Xpos_Click(object sender, EventArgs e)
        {
            SendCommand("Jog3=0");
        }

        private void btn_Xneg_Click(object sender, EventArgs e)
        {
            SendCommand("Jog3=0");
        }

        void SendCommand(string s)
        {
            try
            {
                KM.WriteLine(s);
            }
            catch (DMException ex) // in case disconnect in the middle of reading status
            {
                MessageBox.Show(ex.InnerException.Message);
            }

        }

        private void btn_Xpos_MouseDown(object sender, MouseEventArgs e)
        {
            SendCommand("Jog3=2000");
        }

        private void btn_Xneg_MouseDown(object sender, MouseEventArgs e)
        {
            SendCommand("Jog3=-2000");
        }

        private void btn_Xpos_MouseUp(object sender, MouseEventArgs e)
        {
            SendCommand("Jog3=0");
        }

        private void btn_Xneg_MouseUp(object sender, MouseEventArgs e)
        {
            SendCommand("Jog3=0");
        }
    }
}
