Sending email automatically?

Helo, how to automate sending email? I want to automatically send email to some addresses every day? How can i do that?
I build that one for my final project at my college. Please help me.
Thanks in advance.
I am using this code....
try
Dim objEmailMessage As System.Web.Mail.MailMessage
Dim objSMTPServer As System.Web.Mail.SmtpMail
objSMTPServer.SmtpServer = "mail.wefgroup.com"

objEmailMessage = New System.Web.Mail.MailMessage
With objEmailMessage
.To = "[email protected]"
.From = "[email protected]"
.Subject = "Helo"
.Body = "I test sending email"

End With

objSMTPServer.Send(objEmailMessage)
catch exc as exception
response.write(exc.innerexception.innerexception.message)
end try

You could always just make a VB.NET exe and then schedule it under windows scheduler...

Is there any alternatives to send email automatically other than Windows Scheduler?

Thanks...

Start a timer when the web application starts up. Then, on fire, check the time, if it is the time to fire off the email, then do it, otherwise do nothing.

This is probably horribly inefficient though for a web app, not sure.

You could create a windows service, install it, and let it run in the background.

helo, thanks for your reply.
How can i check whether the web application is started up?
I want the email send automatically everyday to the user...
How should i code it?

Use the events in the Global.asax file.
I think Application Start is the one you want...not sure.

Thanks.
U mean all we need it just place the email code part at the Application Start in the Global.asax?

can you try this In your global.ascx

VB Code:

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
        ' Fires when the application is started
        Dim myTimer As New System.Timers.Timer
        myTimer.Interval = 5000
        AddHandler myTimer.Elapsed, AddressOf myTimer_Elapsed
        myTimer.Enabled = True
    End Sub
 
    Protected Sub myTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs)
        'run your code that determines if it time to send emails
        'and if so call procedure/function that sends them
    End Sub

Timer interval is in milliseconds so in your case you'll probably want it to be a lot bigger than 5000.

EDIT: I suppose you could even set the timer interval to 86400000 (1 day) but then you are relying on the server to be running 24 hours a day without any problems which isn't a good idea.

This isn't a good idea for another reason possibly. ASP.NET apps will end if there is no activity. I don't know if having a timer going would prevent it from stopping or not. Only testing would expose everything.

What about an HttpModule? You install the module in the WebConfig

Code:

---

<httpModules>
    <add name="Timer" type="TimerModule, TimerModule" />
</httpModules>

---

You inherit System.Web.IHttpModule(I think that's right.) and override OnBeginRequest? That means every request your OnBeginRequest is fired and whatever code is there runs. It needs to be fast. Super duper fast.
