Displays a hierarchy list of shell items (folders and files).

A FolderView control provides functionality identical to the tree pane in Explorer. It displays a list of folders (and files) and allows browsing of the shell s entire namespace. Though it exposes and returns many properties and methods similar to that of the familiar TreeView control, it provides many other unique features: - The background of the control can be set to any color or a tiled graphic. The graphic may scroll with the contents. The fore color can also be customized. - The control can be customized to any appearance, including how it displays folder connecting lines and buttons ("+", "-"), the distance that folders are indented within the control, whether shared folders display associated share icons, and checkboxes. - Implements optional auto refresh mode, where any changes within the shell s namespace (such as renaming, moving or deleting items) are automatically and immediately reflected in the control. - Allows control of whether the shell will automatically display error messages as a result of invalid folder selection (i.e. selecting a removable drive containing no disk or selecting a disconnected network share).
