How can I change what's on the Places Bar of a common dialog box?

How can I add an item to the Places Bar on the left side of a standard file dialog box (TOpenDialog), where there are usually "Desktop", "My Computer", "My Documents", "My Network", etc.?

Still a question how therefrom to clean standard buttons and whether it is possible to make it?

There's an article by Fikret Hasovic here: http://fhasovic.blogspot.com/2004/09/custom-places-bar.html that links to the MSDN article on it, and he provides Delphi code to download.
