I am writing a program that parses through rss feeds in craigslist and displays the date, title, link and description and writes it to sql database.

I have 2 taks that I need help with.

1. Prevent the program from entering duplicate data. For example, somoene might repost their ad more than once within a few minutes.

2. Set up a timer that automatically uploads the data every, say 10 minutes.

Thank you,

There is a lot of code required to implement all of this. What have you done so far and what exactly did you need help with?

So far I creates a class. Loaded the page(Page_Load) with array of sites, method to insertREcord into sql database, method to process RSSItem and load data to sql DB.
What I need is either a tutorial and example code that shows me how to write a method that prevents duplicate postings from being entered into the database.
Also I need to see some code that shows me how to use a timer to activate the reader every so many minutes instead of running contiously.
Thank you.

What are you stuck on? Preventing duplicate data from being entered is quite simple. A timer? You can steer the app from the outside to kick off ever x minutes, it's not a bad option if it need not be persistent/always running.
