Take automatic snapshot (screenshot) and email it using asp.net (C#, VB)

Introduction: In this article I will explain how to take automatic snapshot/screenshot of desktop or a particular open window and email it as attachment using asp.net (C#, VB)

Description:

In the previous article I have explained  How to take snapshot (screenshot) using asp.net (C#, VB),  Upload multiple files and save their pathto database using Fileupload control in asp.net and Create Temporary table dynamically and bind to Gridview in asp.net.

In this example I want to take the screenshot in every 1 minute. To implement this I add Timer control to .aspx and set interval (60000).

Note: -      1 second = 1000 Millisecond

Html Markup Of page:

<asp:ScriptManager ID="ScriptManager1" runat="server">

     </asp:ScriptManager>

     <asp:Timer ID="Timer1" runat="server" ontick="Timer1_Tick" Interval="60000">

     </asp:Timer>   

Note: - First of all we have to add the reference of System.Windows.Forms library.

C# Code:

using System.Windows.Forms;

using System.Drawing.Imaging;

using System.Drawing;

using System.Net.Mail;

public void SendEmail(string path)

    {

        try

        {

            MailMessage mail = new MailMessage("EmailSender", "Email TO");

            mail.Subject = "Screen Shot";

            Attachment objAttachment = new Attachment(path);

            mail.Attachments.Add(objAttachment);

            SmtpClient smtp = new SmtpClient();

            smtp.Host = "smtp.gmail.com";

            smtp.Port = 587;

            smtp.Credentials = new System.Net.NetworkCredential("EmailId", "Password");

            smtp.EnableSsl = true;

            mail.IsBodyHtml = true;

            smtp.Send(mail);

        }

        catch (Exception ex)

        {

         

        }

    }

   

    protected void Timer1_Tick(object sender, EventArgs e)

    {

        Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);

        Graphics graphics = Graphics.FromImage(bitmap as System.Drawing.Image);

        graphics.CopyFromScreen(5, 5, 5, 5, bitmap.Size);

        string path =("E:/ss/" + Guid.NewGuid() + "ScreenShot.png");

        bitmap.Save(path);

        SendEmail(path);

    }

VB Code:

Imports System.Drawing.Imaging

Imports System.Drawing

Imports System.Windows.Forms

Imports System.Net.Mail

Public Sub SendEmail(ByVal path As String)

        Try

            Dim mail As New MailMessage("Email Sender", "Email To")

            mail.Subject = "Screen Shot"

            Dim objAttachment As New Attachment(path)

            mail.Attachments.Add(objAttachment)

            Dim smtp As New SmtpClient()

            smtp.Host = "smtp.gmail.com"

            smtp.Port = 587

            smtp.Credentials = New System.Net.NetworkCredential("EmailId", "Password")

            smtp.EnableSsl = True

            mail.IsBodyHtml = True

            smtp.Send(mail)

        Catch ex As Exception

            Throw ex

        End Try

    End Sub

    Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick

        Dim bitmap As New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)

        Dim graphics__1 As Graphics = Graphics.FromImage(TryCast(bitmap, System.Drawing.Image))

        graphics__1.CopyFromScreen(5, 5, 5, 5, bitmap.Size)

        Dim path As String = ("E:/ss/" & Convert.ToString(Guid.NewGuid()) & "ScreenShot.png")

        bitmap.Save(path)

        SendEmail(path)

    End Sub
