vb.net get link url on click [webbrowser]

Hi so i have created a http verb tampering browser it uses httpweb requests to load the site and then pu the sites html code into a string and then place that html into the webbrowser.documentText

now if anyone has ever done this you will know all you are doing is downloading the pages html to a string on your local computer and because of this images and links are not shown because it cuts the url such as http://site.com from all urls

well i have used regex to add that back to all image and link tags

but the thing is wen i do this i then need to get the url of any clicked link of the page and put it into a text box with out the webbrowser navigating

dose anyone know of a way to do this ?
