C# Process Monitoring

[Prodian]

Im trying to monitor a process until the process ends but the program keeps freezing during the while loop and wont keep running. Heres what I have so far:

private void ProcessCheck()
        { 
            bool done = false;
            while (!done)
                {
 
                 System.Diagnostics.Process[] myProcesses;
            myProcesses =
               System.Diagnostics.Process.GetProcessesByName("gsengine");   
 
if (myProcesses != null)
                    {
                        tabPage2.Enabled = false;
                        tabPage3.Enabled = false;
                        tabPage4.Enabled = false;
 
                        Start.Visible = false;
                        stop.Visible = true;
                        toolStripStatusLabel1.Text = "CORE RUNNING!";
 
 
                }
 
                    if (myProcesses == null)
                    {
 
                        tabPage2.Enabled = true;
                        tabPage3.Enabled = true;
                        tabPage4.Enabled = true;
 
                        Start.Visible = true;
                        stop.Visible = false;
 
                        toolStripStatusLabel1.Text = "CORE STOPPED FOR SOME REASON!";
 
                        done = true;
                    }
            }
        }

Any ideas how I can get this working?

The code here is not looping, obviously. One option is to set done to true and in case null set to false

Ive used this method in other programs and it loops fine. I think the problem is the null part. If I put the done = true on both ifs it doesnt freeze but when its only on the == if, the program freezes.no errors. Is there another way Ican monitor to check to see if the process is still running?

If anybody is interested I got this working as well, at first it was using 100% cpu until I added the Thread.Sleep:

private void StillRunning(object result)
        {
 
 
            if (!InvokeRequired)
            {
 
                    Start.Visible = false;
 
                    stop.Visible = true;
 
                    tabPage2.Enabled = false;
 
                    tabPage3.Enabled = false;
 
                    tabPage4.Enabled = false;
 
                    toolStripStatusLabel1.Text = "GSMS STARTED!";
 
                    wizardToolStripMenuItem.Enabled = false;
 
 
            }
            else
            {
                Invoke(new StillRunningHandler(StillRunning), result);
 
            }
 
        }
        private void First_Thread()
        {
            Thread current_thread = Thread.CurrentThread;
 
            bool done = false;
 
            if (current_thread.IsAlive == true)  //Start of Thread is Alive
            {
                while (!done)               //Start of While Loop
                {
                   Process[] pname = Process.GetProcessesByName("gsengine");
 
                    Thread.Sleep(500);
 
                    if (pname.Length == 0)          //Core Stopped, Do this.
                        {
                           StoppedRunning(0);
 
                            current_thread.Abort();     //Stop Thread NOW
 
                            done = true;        //Get out of While Loop NOW
                        }
                    else                        //Core is running, Do this.
 
                        {
 
                        StillRunning(0);
 
                        }                    
                }           //End of While Loop
            }               //End of If Thread is Alive
 
            else
                {
                    toolStripStatusLabel1.Text = "Thread is not running, what happened?";
                }
        }
 
        private void ThreadStart()
        {
            ThreadStart thr_start_func = new ThreadStart(First_Thread);
            Thread fThread = new Thread(thr_start_func);
            fThread.Name = "first_thread";
            fThread.Start();    //starting the thread
 
        }
