Hi all
I wanna do something like timing with ASP.net(c#).
for example I specify a date for sending an email (or any other jobs).
How can I do this? I don't have any idea.

any suggestion can help me.

thanks in advance.

I got these code from web

Code:

 
<html>
<head>
    <title>Scheduling - Method 1</title>
</head>
<body>
<p>
    This script will print out &quot;Do Something!&quot; at the
    first request and then at the first request after midnight
    every day.
</p>
<%
' The way it stands, the "Do Something" line will run the first
' time it's hit after the web server starts and then again every
' day at the first hit after midnight.  If no one hits it for a
' day it won't run until hit.  This can be troublesome when
' you're doing a calculation which expects a day to have elapsed.

' Along the same lines, to make it not run upon starting,
' uncomment this section:
'If Application("LastScheduledRun") = 0 Then
'    ' Set the "LastScheduledRun" variable to something to
'    ' satisfy the condition checked below.  I'm setting it
'    ' to the current time, hence making the computer think
'    ' it just got done running it so there's no need to do
'    ' so again.
'    Application.Lock
'    Application("LastScheduledRun") = Now()
'    Application.UnLock
'End If

' Useful Debugging Lines:
'Response.Write Application("LastScheduledRun") & "<br />" & vbCrLf
'Response.Write Now() & "<br />" & vbCrLf
'Response.Write DateDiff("d", Application("LastScheduledRun"), Now()) _
'    & "<br />" & vbCrLf

' DateDiff works a little differently than you might expect.  If
' you ask for the difference in days, it does not check to see
' how many days worth of time have elapsed between two dates,
' but simply takes the dates and subtracts them.  Hence... from
' Jan 1, 2002, 11:59PM to Jan 2, 2002, 12:01AM returns 1 day even
' though in reality it's only been a couple seconds.  This makes
' it ideal for triggering stuff at midnight like we're doing here.
'
' If days between "LastScheduledRun" and the current time is > 0,
' this must be the first hit after midnight so we run our daily
' routine.  This condition is the key to what type of schedule is
' kept.  It can be changed to hourly, every 10 minutes, or even
' the first hit after 5pm... whatever you want, but it won't ever
' run unless someone has hit the page containing it.
If DateDiff("d", Application("LastScheduledRun"), Now()) > 0 Then
    ' This is where you put the commands you want to run on the
    ' schedule set up by the above condition.
    Response.Write "Do Something!"
        
    ' Reset our "LastScheduledRun" variable to the current date
    ' and time indicating we just did it.
    Application.Lock
    Application("LastScheduledRun") = Now()
    Application.UnLock
End If
