Codeproject is a tremendous ressource to provide some good examples on how to deal with certain problems/technologies. For that matter, you usually would want to download the sample-code provided by the author and just go right to the source.
This typically involves a number of repetitive steps: browse to the article, download the source, unzip it to a unique directory, open it with Visual Studio and finally review the code with the article.
I just stumbled across a knowledge-base entry, which originally dates back to 2007. This article introduces a codeproject browser extension to visual studio. So now you can just download the source from within visual studio jump to the project and reference back to the article – all without leaving Visual Studio – this is cool.
