Form Design

I have added two PictureBox controls in the Form and 7 Button controls.

C#

using WebCam_Capture;

namespace _WebCam_PictureBox

    class WebCam
    {
        private WebCamCapture webcam;

        private int FrameNumber = 30;
        public void InitializeWebCam(ref System.Windows.Forms.PictureBox ImageControl)
        {
            webcam = new WebCamCapture();
            webcam.FrameNumber = ((ulong)(0ul));
            webcam.TimeToCapture_milliseconds = FrameNumber;
            webcam.ImageCaptured += new WebCamCapture.WebCamEventHandler(webcam_ImageCaptured);
            _FrameImage = ImageControl;
        }

        void webcam_ImageCaptured(object source, WebcamEventArgs e)
        {
            _FrameImage.Image = e.WebCamImage;
        }

        }

        public void Continue()
        {
            // change the capture time frame.
            webcam.TimeToCapture_milliseconds = FrameNumber;

            // resume the video capture from the stop.
            webcam.Start(this.webcam.FrameNumber);
        }

        public void ResolutionSetting()
