#127 Visual C#: Screenshot Grabber – Take screenshots automatically


I needed a tool that takes screenshots at a regular interval. No bells and whistles, just simple tool where you can specify at what interval you can take the screesnhots, the destination folder and the monitor (if you have more than one). It looks like this.

Click Start when you are ready and the tool will minimize itself. When you are done, double-click the icon in the tray or right-click on it and choose Open where you can Stop the screesnhot grabbing.

Here is the source for your review but you’ll need the whole C# solution in order to work. Get it (git clone) from github. You’ll need .NET 3.5. Here is the EXE.

using System;
using System.Drawing;
using System.Windows.Forms;
using System.Drawing.Imaging;
using System.IO;

namespace SSG
{
    public partial class Form1 : Form
    {

        //Get all available monitors
        Screen[] scrScreens = Screen.AllScreens;

        public Form1()
        {
            InitializeComponent();
        }

        private void btnFolderBrowser_Click(object sender, EventArgs e)
        {
            //Shows up the browse dialog for the destination files
            DialogResult drResult = fbdBrowserDialog.ShowDialog();
            if (drResult == DialogResult.OK)
            {
                tbFolder.Text = fbdBrowserDialog.SelectedPath;
            }

        }

        private void btnRecord_Click(object sender, EventArgs e)
        {
            //Check if valid interval
            int intInterval = 1000;
            if (!(Int32.TryParse(tbInterval.Text, out intInterval)))
            {
                MessageBox.Show("Not a valid interval.", "SSG", MessageBoxButtons.OK, MessageBoxIcon.Error);
                return;
            }
            if (intInterval < 1)
            {

                return;

            timTimer.Interval = intInterval * 1000;
            //Check if folder exists
            if (!(Directory.Exists(tbFolder.Text)))
