InvokeRequired ckeckbox

Første problem der lige springer mig i øjene er din "SetAlarmVac"
if (checkBoxVac.InvokeRequired)
                checkBoxVac.Invoke(new CheckboxDelegate(SetAlarmVac), new[] {alarm });
else
            checkBoxVac.Checked = alarm; 

Du mangler en else i den ... eller bliver checkBoxVac jo sat lige meget om det er form thread owner eller ej ...

// ouT

sådan ?
using System;
using System.Windows.Forms;

namespace Hysteresis
{
    public class ValveAlarmView
    {
        CheckBox checkBoxVac;
        CheckBox checkBoxAtm;
        private delegate void CheckboxDelegate(bool alarm);
       

        public ValveAlarmView(CheckBox checkBoxVac, CheckBox checkBoxAtm)
        {
            this.checkBoxVac = checkBoxVac;
            this.checkBoxAtm = checkBoxAtm;
        }

        public void SetAlarmVac(bool alarm)
        {

            if (checkBoxVac.InvokeRequired)
                checkBoxVac.Invoke(new CheckboxDelegate(SetAlarmVac), new[] {alarm });
            else
                checkBoxVac.Checked = alarm; 
        }
        public void SetAlarmAtm(bool alarm)
        {
            if (checkBoxAtm.InvokeRequired)
                checkBoxAtm.Invoke(new CheckboxDelegate(SetAlarmAtm), new[] { alarm });
            else
                checkBoxAtm.Checked = alarm;
        }
    }
}

det giver desværre fejlmeddelsen:


System.ArgumentException: Object of type 'System.Boolean[]' cannot be converted to type 'System.Boolean'.

Fordi du angiver et array ... og din delegate siger du sender en enkel bool med ...

Prøv:
checkBoxAtm.Invoke(new CheckboxDelegate(SetAlarmAtm), alarm );

Ja selvfølgelig !

Sådan?
using System;
using System.Windows.Forms;

namespace Hysteresis
{
    public class ValveAlarmView
    {
        CheckBox checkBoxVac;
        CheckBox checkBoxAtm;
        private delegate void CheckboxDelegate(bool alarm);
       

        public ValveAlarmView(CheckBox checkBoxVac, CheckBox checkBoxAtm)
        {
            this.checkBoxVac = checkBoxVac;
            this.checkBoxAtm = checkBoxAtm;
        }

        public void SetAlarmVac(bool alarm)
        {

            if (checkBoxVac.InvokeRequired)
                checkBoxVac.Invoke(new CheckboxDelegate(SetAlarmVac), new {alarm });
            else
                checkBoxVac.Checked = alarm; 
        }
        public void SetAlarmAtm(bool alarm)
        {
            if (checkBoxAtm.InvokeRequired)
                checkBoxAtm.Invoke(new CheckboxDelegate(SetAlarmAtm), new { alarm });
            else
                checkBoxAtm.Checked = alarm;
        }
    }
}

Det giver fejlen:

Du skriver jo ikke hvad jeg skrev ...

new {} laver en anonym type ... du skal bare smide "alarm" ind.

Jeg er nok lidt laaangsom, men nu virker det:-)
Sender du et svar ?
