Those commands require document templates, connectors etc. It is more
a full blown docview application. Like in vdrawm and vdraws.
For just a canvas, the simple sample now shows you how to save and
load contents into it. Did add it just now.
The principles are the same, but only at a lower level, which is what
you need in your case.

The derived class you need is
a2dIOHandlerCVGIn and a2dIOHandlerCVGOut which is the default format
to save a a2dCanvasDocument.
And i assumed you did know about that, since for saving and loading
files you normally need to setup document templates ( see vdraw and
vdrawm for example ).
Although it looks like a2dCanvasDocument::SaveObject() takes this as
the default handler if not specified.
Anyway the simple sample shows you now how to do it for a simple canvas.

Thanks, if you find problem in the simple sample, save and loading
files, come b
ack on it.
