querycanceldocumentclose event

[Visio]

Hi,

For some reason this event is not firing when a user selects the close
window from within visio. I have developed an add-in project in vb.net for
this. BeforeDocumentClose is firing but at this point the page is already
closed and i am unable to get some cell information. I want to write some
cell information to the database once a user selects 'Save' when they close
the document.

Any suggestions
