it should still fix some issue So, it worked out.
In the event that is called back to in the BackgroundWorker wrapper class I did the following as per Nick's suggestion:
code :
private void updtStatus(object sender, EventArgs e)
    { if (MainForm.InvokeRequired)
      { MainForm.Invoke(new DoUIWorkHandler(MainForm.updtStatus), new object[] { sender, e }); }
    }
public delegate void DoUIWorkHandler();
public delegate void DoUIWorkHandler(object sender, EventArgs args);

I think the issue was by ths following , This is one of the points of a background worker in essence. Use a ProgressBar and just determine how far along the progress is, according to your algorithm.
(As has been mentioned, if they're 10% through, send 10, if they're 50% through, send 50)
code :
bgWrk.ProgressChanged += new System.ComponentModel.ProgressChangedEventHandler(bgWrk_ProgressChanged);
// Note: This method is invoked on the UI thread

void bgWrk_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    // Add progress to whatever UI element needs updating. The below simply uses a progress bar.
    prog.Value = e.ProgressPercentage;
}

Hope that helps I have a simple Windows based application. I used BackgroundWorker for sending mails one by one. Here is the DoWork event handler code , I got answer
code :
(sender as BackgroundWorker).ReportProgress((int)(100.0 / totalSteps * i), null);

  void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {

        progressBar1.Value =(int) e.ProgressPercentage;
    }

I think the issue was by ths following , As mentioned by jmcilhinney, the solution for my answer is very simple.
Just let the BackgroundWorker update the progress bar at the background. And when it finished doing it's work, the progress bar will be at 100 which means it is completed.
code :
Private Sub BackgroundWorker1_RunWorkerCompleted(sender As Object, e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles BackgroundWorker1.RunWorkerCompleted

        If e.Cancelled = True Then
            ProgressBar1.Value = 0
            Label8.Text = ""
        ElseIf e.Error IsNot Nothing Then
            MessageBox.Show(e.Error.Message)
        Else
            MessageBox.Show("Completed!")
            Form1.TabControl2.TabPages(1).Controls.Add(fresult)
        End If
    End Sub

it fixes the issue You could have your background worker signal progress (WorkerReportsProgress property set to true, then calling ReportProgress).
In that event handler (OnProgressChanged), invoke another public event you create that signals receivers that data should be updated. Your admin form could subscribe to that event.
