I've been looking into using getShap(), but doesnt it require the index of
the shape? Not all databases will have this Index. I think you can get the
shap via a class, but the shapeObj doesnt seem to work correctly. Do you
have any sample code for drawing a shape, getting the shape by class, not by
the shape index?
