Scheduling a task with VB Script and Windows Task Scheduler.

Hi,

 I need to have a scheduler execute a web page on my my machine with VBS Script and Windows Task Scheduler.

The referred link is
http://weblogs.asp.net/steveschofield/archive/2006/09/28/Schedule-a-task-to-call-a-webpage-using-Task-scheduler_2E00_.aspx
As per the link

My vb script is(script file name is HttpRequester.vbs)
-------------------------------------------------------------------
On Error Resume Next
Dim objRequest
        Dim URL
Set objRequest = CreateObject("Microsoft.XMLHTTP")
URL = "http://localhost:59393/TaskScheduler.aspx"
 objRequest.open "POST", URL , false
objRequest.Send

The TaskScheduler.aspx will have some database related operations.for the testing purpose i am having only a repose.write method in the load event of the aspx page.

Aspx.cs  page is
---------------------
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace FTMS
{
    public partial class TaskScheduler : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write("TaskScheduler.aspx was called:" + System.DateTime.Now);
        }
    }
}

I need to display this message while executing the task scheduler.

I set up the windows task scheduler to run daily once.
But instead of showing the message written in the load event of the aspx page it is opening the vbscript file .

Can anybody please help me on how to schedule this task on windows task scheduler? and is it possible to use javascript file instead of vbscript for scheduling the task?

Thanks
Priya

I've found that using the SCHTASKS utility is a really good way of managing scheduled tasks.
'Creates a schedulded Task to run 2 minutes from NOW
'You can manually set the start time by using the following format:
'
'strStartTime = 21:30:00
'
Set objShell = CreateObject("Wscript.Shell")
strComputer = "."

'************************
'Run 2 Minutes from Now
'************************

datDate = DateAdd("s", 120, Now())
datLongTime = FormatDateTime(datDate, 3)

If Instr(datLongTime, " PM") Then
	strStart = Replace(datLongTime," PM","")
	arrStartTime = Split(strStart, ":")
	strHour = arrStartTime(0) + 12
Else
	strStart = Replace(datLongTime," AM","")
	arrStartTime = Split(strStart, ":")
	strHour = arrStartTime(0)
End If

strStartTime = strHour & ":" & arrStartTime(1) & ":" & arrStartTime(2)

'************************
'Schedule the Task
'************************
strCommand = "schtasks /create /tn ""Task Name"" " & _
		"/tr ""C:\MyScript.vbs"" /sc once /sd 09/21/2010 /st " & strStartTime & " /ru Domain\JSmith /rp Pa$$w0rd /f"

objShell.Run(strCommand)

Open in new window

Does your Task Scheduler show the file in Notepad or some other editor?
If so, you probably want to change the program in your scheduled task to something like:

wscript.exe c:\myscript.vbs

Some admins change the default behavior of scripts to open in NOTEPAD to prevent malicious code from entering the environment and running if someone just clicks on it.

It can't since it's not running in the correct environment.  Change your program to run wscript with the script path + name as the argument in Task Scheduler.
