Auto subscription renewal

That's a fairly broad question on a somewhat involved task, and "assistance in detail" for such a question is probably beyond the scope of a forum such as this. ;)

But, to offer less detail and more of an overview...

Subscriptions will need to be stored in a database.  A simple Windows service, or scheduled task, to query the database daily WHERE Expires < TODAY() AND AutoRenew = True.  Then process the payment, and if successful update the database with the new subscription details; the System.Net.Mail classes can provide you the means to notify the customer.

hello tqerbert:

Thanks for your response, I understand that data is stored in a database I have got the sql 2008 schema in place, I was uncertain as to when the subscription expires how does the payment take place, and how is the email sent?? is the email sent via SQL or does a scheduled task run the classes in the website?? and how does the payment take place automatically until the client unsubscribes?

wonderfull
