Question

I am working on a C# windows form application. How can i edit my code in a way that when more than 2 faces is being detected by my webcam.

More information:

When “FaceDetectedLabel.Text = “Faces Detected : ” + cam.facesdetected.ToString();” becomes Face Detected: 2 or more…

How can i do the following:

• Minimize all program running except my application.

Here is my code:

namespace PBD
{
    public partial class MainPage : Form
    {
        //declaring global variables
        private Capture capture;        //takes images from camera as image frames

        public MainPage()
        {
            InitializeComponent();
        }

        private void ProcessFrame(object sender, EventArgs arg)
        {
            Wrapper cam = new Wrapper();

            //show the image in the EmguCV ImageBox
            WebcamPictureBox.Image = cam.start_cam(capture).Resize(390, 243, Emgu.CV.CvEnum.INTER.CV_INTER_CUBIC).ToBitmap();
            FaceDetectedLabel.Text = "Faces Detected : " + cam.facesdetected.ToString();
        }

        private void MainPage_Load(object sender, EventArgs e)
        {

            #region if capture is not created, create it now
            if (capture == null)
            {
                try
                {
                    capture = new Capture();
                }
                catch (NullReferenceException excpt)
                {
                    MessageBox.Show(excpt.Message);
                }
            }
            #endregion

            Application.Idle += ProcessFrame;
        }

How to programmatically minimize opened window folders

You’ll have to enumerate all processes and exclude the current one (yours) instead of getting the “explorer” one. I’d suggest also putting exception handling and some checks in place since not all processes have windows to be minimized
