Progress bar with process C#

How to attach a process bar with a process in C#...

Let we want to add 1 to 100 numbers in a list box and runs a progress bar to show the process percentage.

1. Create a window form application. Design a form with a Listbox to insert the values and with a progress bar to show the process. Also a button to start that process.

2. Now add a backgroundworker control from toolbox. That will add at the bottom of form.

3. You have to add a method for that task you want to perfrom (i.e. in this example we want to add 1 to 100 number in a list. so i create a task method) with the parameters BackgroundWorker bw and DoWorkEventArgs  like 

4. Set Property of Backgroundworker controls.

WorkerReportProcess=true

WorkerSupportCance=true

from property window

   public void task(BackgroundWorker bw, DoWorkEventArgs e)

        {

            if (bw.CancellationPending)  // if cancel button pressed  

            {

                e.Cancel = true;  

            }

            else

            {

                for (int i = 0; i<= 100; i++)

                {

                    listBox1.Items.Add(i);  

                    bw.ReportProgress(i);  //Gives the report of process (value of i as process %age used).

                    System.Threading.Thread.Sleep(1000); // for delay in execution

                }

            }

        } 

     5. Generate the BacgroundWorker.Dowork event by clicking the event from events of backgroundworker.

         
       private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            BackgroundWorker bw = (BackgroundWorker)sender;
            task(bw, e);
        }

  6. To Change the process percentage of ProgressBar1  use ProgressChanged event of BackgroundWorker       control.


private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            progressBar1.Value = e.ProgressPercentage;
        }

7. To show the massage when the process is completed. work on RunWorkerCompleted event of backgroundWorker1 like


   private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            MessageBox.Show("Work Compleated!!!");
        }

8. We use "Thread.Sleep(...)" method of threading. so we also have to set CheckForIllegalCrossThreadCalls = false;  on page_load event


private void Form1_Load(object sender, EventArgs e)
        {
            CheckForIllegalCrossThreadCalls = false;
        }

9. To start procss on the button write in button1_click(...)



 private void button1_Click(object sender, EventArgs e)
        {
            backgroundWorker1.RunWorkerAsync();
        }

10. You may take a "Cancel" button on form to cancel the running process. For cancel the process you write the code.


   private void button2_Click(object sender, EventArgs e)
        {
            backgroundWorker1.CancelAsync();
        }

Now as you click the Start Process button the process will start and progress bar show how much process is completed!!!
