simpe code to upload a file

Hi ppl
I am very very newbie in asp coding
I couldn't understand the concept of web coding, I mean where to put servrside codes, where to put clientside codes and how exactly procedures interact with each other.

but now, I need to have a simple page just to upload a file from client to server, just like the page you add file to your email...

if anyone can do me a favor and write it with VB.. I'd really appreciate it.

by the way, tell me please what exactly is the requirement to let IIS run ASP.net codes...

thanks in advances
