viewing system folders

Question

Hi, How can I browse through local shell folders such as the desktop and 'my computer' inside a treeview? I have tried using SpecialFolders, but It only points me to the file folder compatable to the special folder, which does not contain all I need (e.g. the Desktop doesn't contain My Computer, and My Computer doesn't exist). I want something like in the windows explorer - like the FolderBrowserDialog but not in a new window but inside a treeview, so I can handle this information on my own. Thanks!
