ReportProgress

ProgressChanged

private void AdjustControls()
        {
            if (this.InvokeRequired)
            {
                this.Invoke(new MethodInvoker(this.AdjustControls));
            }
            else
            {
                label1.Text = "Whatever";
            }
        }

myBackgroundWorker.ReportProgress(50); // Report that the background worker has got to 50% of completing its operations.

progressBar1.Value = e.ProgressPercentage; // Change a progressbar on the WinForm
