  31         \brief Owner-Draw Default Button is a base class for owner-draw buttons that provides basic
  32         support for default state handling.
  33
  34         Derived class can indicate the default state when appropriate simply by calling
  35         COddButton::IsDefault method to determine the default state and using
  36         any visual effect (e.g. a thin black frame around the button) when it becomes default.
  37
  38         \note A special static method COddButton::SetDefID can be used to set the default button
  39         for the dialog to work around the problems with using a CDialog::SetDefID described in MS kb Q67655
  40         (<A HREF="http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q67655&">
