["Benjamin Fu" <benjamin_fu@xxxxxxx>]

hi, all,
Here is a case makes me headachy for days:
I want to create a element together with a gmf runtime Note and a link 
between my element and the Note, I have found there is AddNoteAction that do 
the similar work, but before call AddNoteAction the element which want to be 
added with Note must be exist already. My case is how to create my element, 
the Note and the link together?

br,
ben
