Backlink Checker

I would like a desktop software tool to check backlinks or inbound links for Websites. VB 6 or VB.net or Revolution are preferred but all will be considered. The tool should do the following: ? Allow the user to check for links from Google or Yahoo ? Allow the user to enter the main URL to the site and have the tool automatically dig down to detect deep links ? Show the URL of the page linked from ? Show the URL of the page linked to ? Show the Google PageRank (PR) of the page linked from ? Identify the anchor text (clickable text) used in the link ? The software must also have a clickable image and text link to visit a Web page. This software will be given to my affiliates to promote a product so I will need to be able to easily change the URL the image and text link leads to. ? Thanks!
