 Module Name:

    e.cpp

 Abstract:

    This DLL Hooks CreateWindow, DialogBox, and CreateDialog routines in order to
    ensure that Comctl32 version 5 is loaded.

 Notes:
    
    This is a general purpose shim.

 History:

    05/25/2000 lamadio  Added initial shims to ensure that comctl32 version 6 
                        is loaded.
