  • Ensure that you are using VC10 (Visual Studio 2010), and also ensure v100 is set as Platform Toolset in project settings.
  • Include <afxdialogex.h>, preferbly in stdafx.h

If you can't use CDialogEx, you may need to write OnEraseBkgnd and do background paining yourself, and would also need handle backgrounds of controls via OnCtlColor
