Abstract:

    Mapping property page (settings) implementation.

Author:

    Don Ryan (donryan) 02-Feb-1995

Environment:

    User Mode - Win32

Revision History:

    Jeff Parham (jeffparh) 30-Jan-1996
        o  Added new element to LV_COLUMN_ENTRY to differentiate the string
           used for the column header from the string used in the menus
           (so that the menu option can contain hot keys).
