Hello Friends,

I am developing project on Activity Screen and system monitoring in C#.net. This is standalone application. In this application, every 10 seconds i want to capture the screenshots of the window. and store those screenshots in locked folder.

This is my Screen Capturing code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Imaging;
using System.Threading;
using System.Security.Principal;

namespace SystemMonitoring
{
    public partial class Form1 : Form
    {
        int pictureCount = 0;
        private static Bitmap bmpScreenShot;
        private static Graphics gfxScreenShot;
       
        public Form1()
        {
            InitializeComponent();
            
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            this.Hide();
           
            for (pictureCount = 0; pictureCount - 1 < pictureCount; )
            {
                bmpScreenShot = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb);
                gfxScreenShot = Graphics.FromImage(bmpScreenShot);
                gfxScreenShot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);

                 bmpScreenShot.Save(@"D:\brinda\" + System.Environment.GetEnvironmentVariable("COMPUTERNAME") + DateTime.Now.ToString("_dd-MM-yyyy_HH_mm_ss") + ".jpeg", ImageFormat.Jpeg);                
                
                Thread.Sleep(10000);
                pictureCount++;
                 
            }            
        }
    }
}
