Flash communication with asp.net

Hi all friends

I am a new action script coder and I am developing my website using asp.net and c#. and my database with sql server 2005. I wan to embed a swf flash file into my webpage.

The flash file will be :
a news ticker which will get its news titles from my db newsTable. I want the user when click the link in the flash file to be redirected to the NewsDetails.aspx?newsId=NewsId where NewsId is the newsId of the selected news
I want to know how to bind a dynamic text in my flash file to a datasource.
Also i want to know how to send a variable containg the querystring value to the destination webpage (NewsDetails.aspx)
