CWnd is transparent

Just trying to create an MFC CWnd window.  Do I need to derive from CWnd or can I just use a CWnd.  Anyway, window is failing to show although I know it is there because i can see it in its iconized state in the task bar and if i click it i get the outline although the inside is transparent.  I would have thought the client area would be white.  It doesn't matter if I register a class or not.  If I supply NULL for the window class the problem is the same.  Please help
      CWnd* pWnd = new CWnd;
      CString strMyClass = AfxRegisterWndClass(
      CS_VREDRAW | CS_HREDRAW,
      ::LoadCursor(NULL, IDC_ARROW),
      (HBRUSH) ::GetStockObject(WHITE_BRUSH),
      ::LoadIcon(NULL, IDI_APPLICATION));
      BOOL success= pWnd->Create(
       NULL,
         strMyClass,
       //strMyClass,
       WS_OVERLAPPED, // if the window doesn't need to be visible you don't need any styles
       CRect(0,0,300,300),
       CWnd::GetDesktopWindow(),
         //this,
       1234);
      if (success)
            pWnd->ShowWindow(SW_SHOW);

I guess the window isn't transparent.  I have attached a screenshot of what i see if i Spy++ on the window.  I know I have the right one.  Why is it black?  It's like a black hole.  Please help this is driving me crazy.
