Edit Added code block, use improve solution to update your question

void Application_Start(object sender, EventArgs e) { 
// Code that runs on application startup System.Timers.Timer myTimer = new System.Timers.Timer(); // Set the Interval to 5 seconds (5000 milliseconds). myTimer.Interval = 86400000; 
myTimer.AutoReset = true; 
myTimer.Elapsed += new ElapsedEventHandler(myTimer_Elapsed); myTimer.Enabled = true; 
} 
public void myTimer_Elapsed(object source, System.Timers.ElapsedEventArgs e) {
 // use your mailer code
 ScheduleMail objScheduleMail = new ScheduleMail(); 
objScheduleMail.SendSurveyMailDaily();
objScheduleMail.SendSurveyMailWeekly(); 
objScheduleMail.SendSurveyMailMonthly(); 
objScheduleMail.SendCampaignMailDaily(); objScheduleMail.SendCampaignMailWeekly(); objScheduleMail.SendCampaignMailMonthly(); objScheduleMail.SendTemplatMailDaily(); objScheduleMail.SendTemplateMailsMonthly(); objScheduleMail.SendTemplateMailsWeekly(); objScheduleMail.EmailRemainders(); 
}

Please improve the question. How exactly are you sending the mails?

Why on earth are you trying to do this in a web application?!? Either use a service or task scheduler for something like this. Your ASP session is probably timing out.

ASP.NET has no state. You should not rely on anything in the Application area even, if you want to set a timer for 24 hours, write a windows service that does your mailing for you.

Well, instead of casting about at random, stick to what works and work out why you're not doing it properly. Ask questions about why you can't make a service work, instead of questions about doing things the wrong way.

it worked out while we are checking it for few minutes in localhost. we are at final stage of our project. when we tested by hosting website for 24 hours we r not receiving mails.

Christian Graus 24-Aug-12 7:25am

Well, then you need to work out why. Fact is, a service is the only viable way to do this, unless you create a stand alone console app that does your mailing and set up a scheduled task to run it. Services are better.

ok can u suggest me how to write?

Christian Graus 24-Aug-12 7:31am

You have a service already. Debug it. I can't tell you how to write a service in a forum reply, no, search the site for articles to do that.

I would suggest you create a ScheduledTask that executes everyday.
Take a look at the Task Scheduler API: http://msdn.microsoft.com/en-us/library/aa383614.aspx

Christian Graus 24-Aug-12 7:36am

Yeah, I said that already. A service is better though.

Kuthuparakkal 24-Aug-12 7:55am

I agree Christian Graus.
I vote for task just because minimal effort compared to service. There are other options if you are willing to stretch.. See my answer.

Solution 2

There are sites usually send Newsletters every week/month. If you take sometime to customize this, will be a sure hit for your website. Ther's no need of scheduler/service etc external to web app...

See this :

I refered a beautiful project in the past, it's called "TheBeerHouse". And is a great stuff. It has Polls, Voting, Articles, NewsLetter, Admin. Also good tutorial for ASP.Net Membership services. Great stuff so far met.

Also you can initiate a thread from Global.asax, this separate thread always monitor and sends anything you like. void Application_Start(Object sender, EventArgs e) {
// Code that runs on application startup
// Your thread initiates here...

}

i wrote it in global.asax

void Application_Start(object sender, EventArgs e)
{

// Code that runs on application startup
System.Timers.Timer myTimer = new System.Timers.Timer();
// Set the Interval to 5 seconds (5000 milliseconds).
myTimer.Interval = 86400000;
myTimer.AutoReset = true;
myTimer.Elapsed += new ElapsedEventHandler(myTimer_Elapsed);
myTimer.Enabled = true;
}
it is not working for 24 hours
is there any other way to give 24 hours time

check this :

Oh buddy dont do that

Interval timers should be user but they should not be used to wait until a certain amount of time has elapsed.

Rather create schedules.

In your case lets say you wish to make sometthign happen 1 day after it has been initialised.
Thake the current Date DateTime.Now.AddDays(1);

then you use your timer that checks every say 1 minute so every 60000 milisecond interval

C#

if(DateTime.Now >= DateTimeSchedule){
   DateTimeSchedule = DateTime.Now.AddDays(1);
   //Do what was scheduled to happen

}

This will ensure that went the PC goes down your timer wont start from the top again

PS as a warning use windows services for this, the reason is that ASP.NET processes gets recycled every odd minutes meaning that even though your timer is running asp.net will decide to recycle the process. meaning your timer will completely shut down.

I got completely burnt on this before there is a way to get around this by using a HTTP web client to reactivate the website when it gets recycled but it gets very messy.

C#

public class TimerStarter
{
    private static Timer threadingTimer;
    public static void StartTimer()
    {

        if (null == threadingTimer)
        {
            threadingTimer = new Timer(new TimerCallback(DoActions), HttpContext.Current, 0, 8640000);
        }
    }
    private static void DoActions(object sender)
    {
        // all your mail calling methods here
    }
}


Then in application_start method in global.asax file.

void Application_Start(object sender, EventArgs e)
    {
         TimerStarter.StartTimer();
    }
