Custom DDX/DDV processing
=========================
This file provides the extra processing which enables the "minimum length" for
CStrings in the Class Wizard.
If you have to rebuild the winforms.CLW file, then you must insert the following
lines in the first section of that file (ie. in the [General Info] section).
They are inserted at the end of the section.
; ClassWizard DDX information for custom DDX functions
