What am I doing wrong? (Custom drawing)

[bops]

Trying to alternate row colors in listview control but handle for selected items.

Message Loop of parent window (DialogBox)

//
case WM_NOTIFY:
{
// NOTE: g_hList is the ListView Control
//         : hWnd is the parent of g_hList (Dialog Window)
    if ( LOWORD( wParam ) == (WPARAM) ID_LIST )
    {
       LPNMLISTVIEW pnm;
       pnm = (LPNMLISTVIEW)lParam;

       if( pnm->hdr.hwndFrom == g_hList && pnm->hdr.code == 
                                                               NM_CUSTOMDRAW )
       {
           SetWindowLong( hWnd , DWL_MSGRESULT , 
                                   (LONG)ProcessCustomDraw (lParam) );
           return TRUE;
        }                
     }
}	
break;

Function to handle it..

LRESULT ProcessCustomDraw (LPARAM lParam)
{
	int iRow;
	LPNMLVCUSTOMDRAW pListDraw = (LPNMLVCUSTOMDRAW)lParam;
	
    switch(pListDraw->nmcd.dwDrawStage)
	{
	   case CDDS_PREPAINT:
       {            
	       return (CDRF_NOTIFYPOSTPAINT | CDRF_NOTIFYITEMDRAW);
       }
	   case CDDS_ITEMPREPAINT:
       {
           if ( pListDraw->nmcd.uItemState == CDIS_SELECTED )
           {
              pListDraw->clrText   = GetSysColor( COLOR_HIGHLIGHTTEXT );
              pListDraw->clrTextBk = GetSysColor( COLOR_HIGHLIGHT );
           }
           else
           {
	          iRow = (int)pListDraw->nmcd.dwItemSpec;
		   
		      pListDraw->clrText   = iRow%2 == 0 ? GetSysColor( COLOR_WINDOWTEXT ) : GetSysColor( COLOR_MENUTEXT );
		      pListDraw->clrTextBk = iRow%2 == 0 ? GetSysColor( COLOR_WINDOW ) : GetSysColor( COLOR_MENU );
           }
		
           return CDRF_NEWFONT;
        }
        break;
	    default:
        break;
	}
	return CDRF_DODEFAULT;
}

I just basically get a blank looking listbox, i.e. the items inside don't show up, but I know they are there because there is a scrollbar.

Thanks.
