Shutdown and Logoff System Events and Windows Services

[adrianojorge]

Good evening to all :) Currently i'm developing a Windows Service in order to automatically send me e-mails with my remote computer operating status. I already checked MSDN documentation about this subject http://msdn.microsoft.com/en-us/library/ycy63t34.aspx and changed the code to use on my situation. But... i don't receive e-mails from it when the remote computer is normally turned off. Someone could help me with this issue? Best Regards.

Can you attach a debugger or at least write some log entries so you can debug what's occurring?

Dear Mark, I'm using Visual C# Express 2005 and i can't find the process debugger on my debug tab. But i can present you the code i'm using:

using System;
using System.ServiceProcess;
using System.Threading;
using System.Windows.Forms;
using System.Diagnostics;
using Microsoft.Win32;
using System.ComponentModel;
using System.Configuration.Install;
using System.Net.Mail;

namespace SimpleServiceCs
{
public class SimpleService : ServiceBase
{
static void Main(string[] args)
{
ServiceBase.Run(new SimpleService());
}

    protected override void OnStart(string\[\] args)
    {
        EventLog.WriteEntry("SimpleService", "Starting SimpleService");
        new Thread(RunMessagePump).Start();
    }

    void RunMessagePump()
    {
        EventLog.WriteEntry("SimpleService.MessagePump", "Starting SimpleService Message Pump");
        Application.Run(new HiddenForm());
    }

    protected override void OnStop()
    {
        Application.Exit();
    }
}

public partial class HiddenForm : Form
{
    public HiddenForm()
    {
        InitializeComponent();
    }

    private void HiddenForm\_Load(object sender, EventArgs e)
    {
        SystemEvents.SessionEnding += new SessionEndingEventHandler(SystemEvents\_SessionEnding);
    }

    private void HiddenForm\_FormClosing(object sender, FormClosingEventArgs e)
    {
        SystemEvents.SessionEnding -= new SessionEndingEventHandler(SystemEvents\_SessionEnding);
    }

//****************************************************************************
// THIS IS THE PART OF CODE STRANGELY NOT WORKING!?!?
//****************************************************************************

    private void SystemEvents\_SessionEnding(object sender, EventArgs e)
    {
        EventLog.WriteEntry("System Logoff or System Shutdown");
        SendEMail("Your System is being Logged Off or Shutdown!");
    }

//****************************************************************************

    private void SendEmail(string Warning){

    //Here goes all the code necessary for sending e-mails from my personal mail account

    }


}

partial class HiddenForm
{
    private System.ComponentModel.IContainer components = null;

    protected override void Dispose(bool disposing)

You should still be able to debug it, but that's a topic for Visual Studio. Do you get the log entry "System Logoff or System Shutdown"? If so, write some log entries in your email code to see if some function is failing.

It could be that the machine does not have an SMTP account configure on it. Before your try to get your service to send an e-mail, try sending an e-mail from the it yourself. After you do that, yo must make sure that your windows service is able to use that SMTP e-mail account.

Dear Mark, Testing my service with attached debugger and with a breakpoint at my SystemEvent Handler (private void SystemEvents_SessionEnding(object sender, SessionEndingEventArgs e)), when i try to logoff or shutdown my pc, that breakpoint is never reached, because the debugger is first disabled. Best Regards.

Dear Silim :) Thank you for your fast response. That was the first test i've done. The smtp mail account is working fine. Only at SystemEvents Handler (private void SystemEvents_SessionEnding(object sender, SessionEndingEventArgs e)) isn't working. Best regards.

MailMessage emailmsg = new MailMessage();
string ids="aa@gamil.com,bb@gmail.com";
string[] mailIDs = .Split(',');

            emailmsg.From = new MailAddress("ganeshbdas1@gmail.com", "name of email");
            foreach (string id in mailIDs)
            {
                emailmsg.To.Add(new MailAddress(id, id));
            }
            string\[\] stringAM = { "AM" };
            emailmsg.Subject = "";

            emailmsg.Body = "";
            emailmsg.IsBodyHtml = true;
            emailmsg.Priority = MailPriority.Normal;
            SmtpClient mailclient = new SmtpClient("smtp.bizmail.yahoo.com");

            mailclient.Credentials = new System.Net.NetworkCredential("ganeshbdas1@gmail.com", "password");
            mailclient.Send(emailmsg);

Hi ganeshbdas, Do you want to tell us something?
