 Module Name:

    CreateResumesQuickandEasy.cpp

 Abstract:

    Hooks all application-defined window procedures and filters out an illegal
    OCM notification code which causes the application to beep annoyingly.

 Notes:


 History:

    03/22/2000 mnikkel  Created
    01/10/2001 mnikkel  Corrected to prevent a recursion problem.
    01/11/2001 mnikkel  Trimmed down to only necessary routines.
