1-How do u figure out in teh main thread that teh worker thread is done its job ?
2- not sure what exactly is teh purpose of Join ..

what attribute /methdod needs to eb checked inorder to enable diable some button upon the worker threads completion.

Code:

---


using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;

namespace ANZ_SHIELD_MIGBAU
{



    public partial class Form1 : Form
    {
        Worker workerObject;
        Thread workerThread;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            btnProcess.Enabled = true;
            btnStop.Enabled = true;
        }
        private void btnProcess_Click(object sender, EventArgs e)
        {
            btnProcess.Enabled = false;
            btnStop.Enabled = true;

            textBox1.Text = "";
            workerObject = new Worker();
            workerThread = new Thread(workerObject.DoWork);

            workerThread.Start();

            while (!workerThread.IsAlive) ;

            Thread.Sleep(1);
           

            ?????????????????????


           
            // Use the Join method to block the current thread
            // until the object's thread terminates.
      //      workerThread.Join();

           

        }

        private void btnStop_Click(object sender, EventArgs e)
        {
            // Request that the worker thread stop itself:
            workerObject.RequestStop();
            textBox1.Text += "process stopped" +workerObject.Get().ToString();
            btnProcess.Enabled = true;
            btnStop.Enabled = false;
        }
    }

    public class Worker
    {
        public void DoWork()
        {
                _status = false;
                for (int j = 0; j < 200; j++)
                {
                    for (i = 0; i < 32000; i++)
                  {
                      if (_shouldStop)
                          break;
                    }
                    if (_shouldStop)
                      break;
                }
                if (_shouldStop)
                    MessageBox.Show("process was interrupted");

                _status = true;
             

        }
        public void RequestStop()
        {
            _shouldStop = true;
        }
        public int Get()
        {
            return i;
        }
        public bool  GetStatus()
        {
            return _shouldStop;
        }

        private volatile bool _shouldStop;
        public bool _status;
        private int i = 0;
    }


}

Your 'Thread' concepts seem weak. First solidify them before implementing them.

P.S.
'Thread.Join()' Blocks the calling thread until a thread terminates.
