Scheduler for aspx page. 3

[whloo]

Hi... I intend to create a web site that will process some data every 10 mins.
Is there any way i can schedule it in IIS? Or i need to get 3rd party software to do it?
Thanks!

I think what you are interested in is ASP.NET page caching:

dalchri,

Thanks for your answer.
But i need something that can go to call my aspx page like every 10 mins or so....

You might be more interested in a windows service with a timer:

using System;
using System.Configuration.Install;
using System.ComponentModel;
using System.Diagnostics;
using System.Runtime.Remoting;
using System.ServiceProcess;

public class Service : System.ServiceProcess.ServiceBase {
   private System.Timers.Timer m_tmr = new System.Timers.Timer(600000);//6 minutes
	private System.ComponentModel.Container components = null;

	public Service() {
		this.InitializeComponent();
        m_tmr.Elapsed +=new System.Timers.ElapsedEventHandler(m_tmr_Elapsed);

	}

	static void Main() {
		ServiceBase[] ServicesToRun = new ServiceBase[] {new Service()};

		ServiceBase.Run(ServicesToRun);
	}

	private void InitializeComponent() {
		components = new System.ComponentModel.Container();
		this.ServiceName = "Timed Service";
	}

	protected override void Dispose(bool disposing) {
		if( disposing ) {
			if (components != null) {
				components.Dispose();
			}
		}
		base.Dispose(disposing);
	}

	protected override void OnStart(string[] args) {
   m_tmr.Enabled = true;
	}

	protected override void OnStop() {
   m_tmr.Enabled = false;
	}

		private void m_tmr_Elapsed(object sender, System.Timers.ElapsedEventArgs e) {
   //Do what you would do on your aspx page here
		}

}

[RunInstaller(true)]
public class ServiceServiceInstaller : Installer {
	private ServiceInstaller HostInstaller;
	private ServiceProcessInstaller HostProcessInstaller;

	public ServiceServiceInstaller() {
		HostInstaller = new ServiceInstaller();
		HostInstaller.StartType = 
			System.ServiceProcess.ServiceStartMode.Automatic;
		HostInstaller.ServiceName = "Timed Service";
		HostInstaller.DisplayName = "10 Minute Timed Service";
		Installers.Add (HostInstaller); 
		HostProcessInstaller = new ServiceProcessInstaller();
		HostProcessInstaller.Account = ServiceAccount.User;
		Installers.Add (HostProcessInstaller);
	}
}

If I remember right there is a project type called windows service that will set most of this up for you.

dalchri,

That's mean i need to write appl in order to run the scheduler?
Can i use web page instead?
It is because i am more comfortable with web page and i need to send email notification as well.
Thanks!

weihann

A web page will time out before the 10 minutes are up.

chiph,

My idea is to write a scheduler that will call the aspx page in like 10 mins interval.
Each time the page will only need few secs to process the data.
Hence, it shouldn't have timeout problem?
Thanks!

weihann.

I agree with the dalchri solution.
In the

       private void m_tmr_Elapsed(object sender, System.Timers.ElapsedEventArgs e) {
   //Do what you would do on your aspx page here
        }

you should call and process the .aspx like here:

private void m_tmr_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
	WebRequest req = null;
	try
	{
		req = WebRequest.Create("[URL unfurl="true"]http://localhost/myweb/MyForm.aspx");[/URL]
		req.Method = "GET";
		req.Timeout = 20000; // seconds
	}
	catch (Exception ex)
	{
	}
}

If yow want to read the results then :

private void m_tmr_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
	WebRequest req = null;
	WebResponse rsp = null;
	StreamReader readStream = null;
	string strRec="";
	StringBuilder sb = new StringBuilder();
	try
	{

		req = WebRequest.Create("[URL unfurl="true"]http://localhost/myweb/MyForm.aspx");[/URL]
		req.Method = "GET";
		req.Timeout = 20000;
		rsp = req.GetResponse();
		Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
		readStream = new StreamReader( rsp.GetResponseStream(), encode );
		Char[] read = new Char[256];
		int count = readStream.Read( read, 0, 256 );
		while (count > 0) 
		{
			String str = new String(read, 0, count);
			sb.Append(str);
			count = readStream.Read(read, 0, 256);
		}
		strRec=sb.ToString();
		sb=null;
	}
	catch (Exception ex)
	{
	}
	
}

Make a web page that auto refreshes every ten minutes.
