how to eliminate extra focus rectangles using CDRF_SKIPPOSTPAINT in customdrawing CTreeCtrl

I want to eliminate these:

My customdraw code is this:

  void MyCTreeCtrl::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)
    {
      LPNMCUSTOMDRAW pNMCD = reinterpret_cast<LPNMCUSTOMDRAW>(pNMHDR);
      HTREEITEM hti;
      switch (pNMCD->dwDrawStage)
      {
      case CDDS_PREPAINT:
        *pResult = CDRF_NOTIFYITEMDRAW;
        itemDC = CDC::FromHandle(pNMCD->hdc);
        break;

      case CDDS_ITEMPREPAINT: // first NM_CUSTOMDRAW notification
        hti = (HTREEITEM)pNMCD->dwItemSpec/*htreeitem*/;

        ... // draw some buttons and symbols

        // As msdn says, let the context determine when events need to occur, so check for last cxnode and then do post paint handler.
        if (cxNode->IsLastNodeInTree())
        {
          *pResult = CDRF_NOTIFYSUBITEMDRAW | CDRF_NOTIFYPOSTPAINT | CDRF_SKIPPOSTPAINT; // notify subitems that they need to be painted as well and then notify post paint
        }
        else
        {
          *pResult = CDRF_NOTIFYSUBITEMDRAW | CDRF_SKIPPOSTPAINT; // notify subitems that they need to be painted as well
        }
        break;

      case CDDS_ITEMPOSTPAINT:
        *pResult = CDRF_SKIPDEFAULT; // don't do any drawing after this (not sure this works)
        break;

      case CDDS_POSTPAINT:
        *pResult = CDRF_SKIPDEFAULT; // don't do any drawing after this (not sure this works)
        break;
      }
    }

The documentation says that by using CDRF_SKIPPOSTPAINT that "The control will not draw the focus rectangle". The code runs fine, but just doesn't do anything with the annoying focus rectangles.

Anyone have experience with this?
