Hi, I am working on an application that uses a checkedlistbox that gets all the names of the processes running in the computer and lists them.

My problem is that I want to create a code that will get all of the checked items in the list and do an action.

for example: foreach (checkedlistbox1.checkeditems.....

{
// a code that will check each process that has been checked and monitor them to see if they are still active.
}

and then a code here that will simply shutdown the computer when the selected processes are exited.

here is the entire code that I have so far

C#

public Form1()
        {
            InitializeComponent();
        }

     
      private  int timming = 5;

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_MouseClick(object sender, MouseEventArgs e)
        {

            //process [] means that your creating a list, the list is called
            //"processlist". and = process.getprocesses(); makes processlist
            //collect all the processes and puts them in the list.

            Process[] processlist = Process.GetProcesses();

            //this code means that for each processes in the processlist do an
            //action with the variable "theprocess".
            foreach (Process theprocess in processlist)
            {
                //pretty much adds all the processes in the checkedlistbox
                //theprocess uses processlist's list of processes and displays
                // all the processes by their names.
                checkedListBox1.Items.Add(theprocess.ProcessName);

                timer1 = new System.Windows.Forms.Timer();
                timer1.Tick += new EventHandler(timer1_Tick);
                timer1.Interval = 5000;
                

                ListB.Enabled = false;

                timming--;

                if (timming == 0)
                {
                    timer1.Stop();

                    theprocess.Refresh();

                    timming = 5;

                    timer1.Start();
                
     
                }

I will appreciate everyone's input

thanks,

Instead of adding the ProcessName to the checkeditemlist add a class like this

C#

public class CustomCheckedItem<t>
{
    public CustomCheckedItem(string Name, T Value)
    {
        this.Name = Name;
        this.Value = Value;
    }

    public string Name {get;set;}
    public string Value {get;set;}

    public override ToString()
    {
        return Name;
    }
}

You can add the process like this

C#

checkedListBox1.Items.Add(new CustomCheckedItem<Process>(theprocess.ProcessName,theprocess);

Then I would make a read only property in the form that returns the checked items as an IEnumerable. You can then run a foreach on the return IEnumerable.

Something like this

C#

private IEnumerable<process> CheckedItems
{
    get
    {
        return checkedListBox1.CheckedItems.Cast<CustomCheckedCtem<Process>>()
            .Select(r=>r.Value);
    }
}

This would show the process name in the list but have the actuall process object in the background that you could access from the IEnumerable.

Bit of a workaround but should work (so long as you fix the bugs I haven't tried the code)
