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

[Prodian]

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
            
        }
