DESCRIPTION: implementation of CNSCBand. 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.
