    feature -- Access

    	bif_browseforcomputer: INTEGER_32 is 4096
    			-- Only return computers. If the user selects
    			-- anything other than a computer, the OK button is grayed.

    	bif_browseforprinter: INTEGER_32 is 8192
    			-- Only return printers. If the user selects
    			-- anything other than a printer, the OK button is grayed.

    	bif_browseincludefiles: INTEGER_32 is 16384
    			-- Requires MVC Version 4.71 or greater. The browse dialog
    			-- will display files as well as folders.

    	bif_dontgobelowdomain: INTEGER_32 is 2
    			-- Do not include network folders below the domain level
    			-- in the tree view control.

    	bif_editbox: INTEGER_32 is 16
    			-- Requires MVC Version 4.71 or greater. The browse dialog
    			-- includes an edit control in which the user can type
    			-- the name of an item

    	bif_newdialogstyle: INTEGER_32 is 64
    			-- Use the new dialog layout with the ability to resize
    			-- Caller needs to call OleInitialize() before using this API

    	bif_nonewfolderbutton: INTEGER_32 is 512
    			-- Do not add the "New Folder" button to the dialog.
    			-- Only applicable with BIF_NEWDIALOGSTYLE.

    	bif_returnfsancestors: INTEGER_32 is 8
    			-- Only return file system ancestors. If the user selects
    			-- anything other than a file system ancestor, the OK button
    			-- is grayed.

    	bif_returnonlyfsdirs: INTEGER_32 is 1
    			-- Only return file system directories. If the user selects
    			-- folders that are not part of the file system, the OK button
    			-- is grayed.

    	bif_statustext: INTEGER_32 is 4
    			-- Include a status area in the dialog box. The callback
    			-- function can set the status text by sending messages to the
    			-- dialog box.

    	bif_usenewui: INTEGER_32 is 80
    			-- Use the new user-interface. Setting this flag provides the
    			-- user with a larger dialog box that can be resized. It has
    			-- several new capabilities including: drag and drop capability
    			-- within the dialog box, reordering, context menus, new folders,
    			-- delete, and other context menu commands. To use this flag,
    			-- you must call OleInitialize or CoInitialize before
    			-- calling SHBrowseForFolder.
    			-- IMPORTANT: to use, requires SHELL32.DLL version 5.00 or higher.
    			-- See class WEL_WINDOWS_VERSION. Is not defined as external
    			-- because it is not yet included in latest versions of "shlobj.h".

    	bif_validate: INTEGER_32 is 32
    			-- Requires Shell32.dll Version 4.71 or greater. If the user types an
    			-- invalid name into the edit box, the browse dialog will call
    			-- the application's BrowseCallbackProc with the
