I decided to try to learn Visual Basic, so I picked up a book that looked promising: Microsoft Visual Basic 2008 Express Edition: Build a Program Now! I've been working through the chapters. In chapter 6, (adding a splash screen) it instructs you to replace the default icon with one from the companion files for the book.
Time to go out and install them, so I flip back to the start of the book to the instructions. The book says to download them from http://www.microsoft.com/mspress/companion/9780735625419. Dead link. I did a search, it pointed me to that same URL. Fortunately, search also surfaced a discussion thread where someone else was hunting for this download and someone else replied "Look here and click the "Companion Content" tab!".
So I thought I'd share.
