Getting started with reporting services SQL Server 2005...help

Hi, I'm building a Web aplication which will feed a SQL 2005 reporting service to send information on a report. I've used the SQL Server 2005 Business Intelligence tool but I've created a simple report with no interaction with the web aplication. The serious question is, is there any tutorial or web site with good step by step how to feed a sql server 2005 reporting service from a ASP.Net web application?This is to be made quickly, it may be quite simple, but I'm quite lost into it too!Thanks for helping!

I read from below site, it helps me to understand.
