// MYLISTBOXITEM class
//
// One object of this class exists for each item in the location dropdown.
//
// Data members:
// psfSub - instance of IShellFolder bound to this container
// pidlThis - IDL of this container, relative to its parent
// pidlFull - IDL of this container, relative to the desktop
// cIndent - indent level (0-based)
// dwFlags -
// MLBI_PERMANENT - item is an "information source" and should
// always remain
// dwAttrs - attributes of this container as reported by GetAttributesOf()
// iImage, iSelectedImage - indices into the system image list for this
// object
//
// Member functions:
// ShouldInclude() - returns whether item belongs in the location dropdown
// IsShared() - returns whether an item is shared or not
// SwitchCurrentDirectory() - changes the Win32 current directory to the
// directory indicated by this item
