DESCRIPTION: the class CNscBand exists to support name
|
||
|
|
space control bands. A name space control uses IShellFolder
|
||
|
|
rooted in various namespaces including Favorites, history,
|
||
|
|
Shell Name Space, etc. to depict a hierarchical UI
|
||
|
|
representation of the given name space.
