Service Starting Problem!

backSlashZero

I have created a windows service to send email on daily basis. It has a timer object that fires an event after 24 hours,

private System.Timers.Timer timer = new System.Timers.Timer (86400000);

In timer event I do my working i.e. I send my emails, something like this:

private void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)
{
eventLog1.WriteEntry("Calling web service for Sending Reminders on " + DateTime.Now.ToLongDateString());
if (EmailObj.SendReminder()) // if sending email is sussful
{
eventLog1.WriteEntry("The operation was successfully completed on " + DateTime.Now.ToLongDateString());;
}
else
{
eventLog1.WriteEntry("There was some error, the operation failed on " + DateTime.Now.ToLongDateString());;
}

if (DateTime.Today.Day == 1)
{
	// first date of month; send emails	
}

}

The problem is, I have installed the service on Windows server 2003, but the service starts and stops immediately with the message “The MyServiceName service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service” I can see the event log entries that I did on OnStart event of the service; also the service is working fine on Windows XP. Please help me I have to run this service on MS Windows server 2003 forever to send emails on daily basis,

What is there in your OnStart() method ? Is your timer enabled ?

You are keeping the thread sleeping for such a long time. Better method to do this is to write a console application which sends mail and exits automatically. Use windows scheduler to schedule this exe to run at required time. So you are not keeping any threads sleeping for long time. Windows service should be used, if it has to do processing all time when it runs, not for scheduling like this, AFAIK.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia How to use google | Ask smart questions

Add a keep-alive thread that doesn't do anything but sleeps for 4.5 seconds.

protected void KeepAliveThread()
{
ServiceController controller = new ServiceController(this.ServiceName);
while (true)
{
if (controller.Status == ServiceControllerStatus.Running)
{
Thread.Sleep(4500);
}
}
}

In your OnStart() method, do this:

Thread thread = new Thread(new ThreadStart(KeepAliveThread));
thread.Start();

Are you doing the following in OnStart()?

timer.Enabled = true;
timer.Start();

Yes i did!

protected override void OnStart(string[] args)
{
eventLog1.WriteEntry("In OnStart: Calling web service for Sending Reminders on "
+ DateTime.Now.ToLongDateString());

EmailObj.SendReminder(); \\\\send reminders if any!
timer.Enabled = true;
timer.Start();

}

cout << "\0"; // its backSlashZero
