Picture Control Revisited

I read the previous thread and it was closed so I'm restarting it. I deliberately chose not to use ColorPicker cpommon dialog because rarely does the color I've picked look good on the full screen. So I created a small 'color picker' where I have a few radio buttons that I've selected and a fairly large picture object. Thinking that I would have a bigger area to see a color. Here is the basis of my code:

      myRect%left = 104
      myRect%top = 12
      myRect%bottom = 96
      myRect%right = 78
      bret = MapDialogRect(hWnd, myRect)
      hDC = GetDC(hWnd)
      if (hDC == NULL) Then
         bret = DeleteObject(myBrush)
         Return
      End If
      iret = FillRect(hDC, myRect, myBrush)    ! this should fill the picture control

where myBrush is created using the RGB values from the dialog radiobutton. I've included the full subroutine and callback as an attachment and a pdf of the dialog. Nothing really happens in the color dialog and I want to understand what I've done wrong to not get a color in the rectangular picture control.

Thanks,
