Please help.....

private void btnStartPic_Click(object sender, EventArgs e)
        {
            int delay = Convert.ToInt32(numericUpDown1.Value);
            int miliseconds = delay * 1000;
            Thread.Sleep(miliseconds);
            this.Refresh();

            cm = new VideoCaptureDevice(wcam[cmbDevice.SelectedIndex].MonikerString);
            cm.NewFrame += new NewFrameEventHandler(cam_newFrame);
            cm.Start();
