I had added the member vairables using the Wizard as Stephen has mentioned,
and of course it had entries in DoDataExchange(). Since I had the class
derived from CPropertyPage instead of CDialog (again from the Wizard), the
OnInitDialog() handler did not get automatically added and DoDataExchange()
did not get called. I've added a handler for OnInitDialog() and called the
base class OnInitHandler() so now it works fine.
