Download a webpage How ?

Hi,

I need to download web pages. I tried using web browser control and navigate to that page and used document.body.innerhtml. it gives the source code inside body tag. however there are couple of problems:

a. it converts all html tags to capital whereas the original web page has lowercase characters.
b. it only provides the source code inside body tag not the whole thing like title, head tags, etc.

please assist at the earliest.

thanks

simplest method i know is to use urldownloadtofile API, several examples in this forum, just specify url and path to save to
