/*
 * The SHFormatDrive API provides access to the Shell
 *   format dialog. This allows apps which want to format disks
 *   to bring up the same dialog that the Shell does to do it.
 *
 *   This dialog is not sub-classable. You cannot put custom
 *   controls in it. If you want this ability, you will have
 *   to write your own front end for the DMaint_FormatDrive
 *   engine.
 *
 *   NOTE that the user can format as many diskettes in the specified
 *   drive, or as many times, as he/she wishes to. There is no way to
 *   force any specififc number of disks to format. If you want this
 *   ability, you will have to write your own front end for the
 *   DMaint_FormatDrive engine.
 *
 *   NOTE also that the format will not start till the user pushes the
 *   start button in the dialog. There is no way to do auto start. If
 *   you want this ability, you will have to write your own front end
 *   for the DMaint_FormatDrive engine.
 *
 *   PARAMETERS
 *
 *     hwnd    = The window handle of the window which will own the dialog
 *		 NOTE that unlike SHCheckDrive, hwnd == NULL does not cause
