 ==Returns==

-==Remarks==
-Applications can replace the menu in a help window by specifying a menu ID in the [[HELPINIT]] structure used when the help instance is created by using the [[WinCreateHelpInstance]] function. If an application replaces the menu, it receives the HM_ACTIONBAR_COMMAND message when the user chooses a command from the menu. Application-supplied menus should have command values in the range Ox7FOO through Ox7FFF.
