Issue with timer

[jagadesh]

HI Guys,

I have an issue with the timer.let me clear
my requirement is i need to send a mail to a user at a particular
time . so i have written a timer and set it to run continuously and
check the database if it matches a date.if it then it sends the mail .
now the issue is this sending of mail is done only when application is
open.so i want to send the mail even my application is not open much
like i need to write some native threads or some sort of thing.


can any one please provide me the some Solution.

thank u
jagadesh

If your application is not open, it is very unlikely to be able to:
- notice it is time to send a mail
- actually send the mail.

What am I getting wrong from your question?

1) write a background task (no GUI, separate from the
user-facing application) whose only function is to
send messages when they are due to be sent.

2) set it to start up when the computer is booted

3) make sure it sends any overdue messages when it is started.

Your choices are:

1. use a chron utility or other tool that comes with your OS.

2. write a small app that hangs around permanently in the background.
to get its size down, compile it natively. See
http://mindprod.com/jgloss/nativecompiler.html

In my night dreams I am writing the code for just such an app to
upload recent changes to my website every 30 minutes and refresh the
various "daily" quotations.

Is chron better than cron ?
