How to list running processes in listbox or a combobox

I am trying to populate a listbox with a list of running processes, so my users can select the process they wish to monitor.

I have tried the following, along with lots of variations of it and I just can't get it to work. 

foreach(Process p in Process.GetProcesses())
{
   listBox1.Items.Add(p.ProcessName);
}

It doesn't do anything, however, I have seen others saying it worked for them. Any ideas?

Solution

  • Have you tried running on a timer or thread?

    OR Insert the code below into the button click event.

    Process[] allProc = Process.GetProcesses(); 
  foreach (Process p in allProc)
                {
                       listBox1.Items.Add(p.ProcessName);
                }
