We wanna develop a SMS and email reminder. The users can set date and time and reminder msg, it can be monthly, daily or weekly.

We need to send sms at the scheduled time, so please kindly advise me what is the best method i can do, by creating an ActiveX component in VB or developing dll in ASP or any other best way.

The only thing coming to my mind is there should be some application running continously on the server, by the way do we really need to have one dedicated server?

We have to run the script for every 5 or 10 minutes.

I think we can do this by task scheduler or with any service, but which will be best for better performance?

Awaiting comments...
