SQL 2008 and using the logged in user, please help

I am new to this, I have searched and searched but cant find the answer im looking for.

Im using visual basic c# and a web app form this is where the users log into the site. (I have sql 2008 application services so the users details update the sql DB)

What im trying to do is have the logged in user select from a dropdown and this update the table in sql, please help me with a statement for the site to update the table for the logged in (on the site) user.

Sorry if this is either too basic or makes no sense lol

thanks for any help
