In my previous articles, I described how to set up the compiler, build a basic BHO, work with regular expressions and fetch pages using XMLHttpRequest’s. I’ve now combined those components into the first working version of PeteSearch in IE. The source code is available through Sourceforge, or you can download it as a zip archive.
This version detects search pages from Google, Live, Ask, Technorati and Exalead, pulls out the search result links, fetches the contents of those pages to ensure they’re still active and relevant, and updates the search page to show each link’s status. I’ll be covering the remaining tasks in later articles, which include implementing hot-keys, adding a split-screen view to IE and writing an installer.
