	// Parameters:
	//     uFlags - Determines the type of items included in an enumeration and can
	//              be one or more of the flags listed in the Remarks section.
	// Remarks:
	//     Styles to be added or removed can be combined by using the bitwise
	//     OR (|) operator. It can be one or more of the following:<p/>
	//     * <b>SHCONTF_FOLDERS</b> Include items that are folders in
	//       the enumeration.
	//     * <b>SHCONTF_NONFOLDERS</b> Include items that are not folders

	//       can return without validating the enumeration object. Validation
	//       can be postponed until the first call to IEnumIDList::Next.
	//       This flag is intended to be used when a user interface may be
	//       displayed prior to the first IEnumIDList::Next call. For a
	//       user interface to be presented, 'hwndOwner' must be set to a valid
	//       window handle.
	//     * <b>SHCONTF_NETPRINTERSRCH</b> The caller is looking for
	//       printer objects.
