How to find an addon from its name?

[effebruno]

Hi,

I was analyzing the Pie Chart shape's ShapeSheet in Visio 2007 (italian) when in the User-defined Cells section I found:

Name: User.WatchSlices
Value: DEPENDSON(Prop.Slices) + RUNADDON("VALP")
Prompt: "Calls VBA procedure to validate slice total."

How could I identify what does the "VALP" addon do and where is it located? If I navigate to Tools|Addons I can find a bunch of names but I really can't figure out if one of them is my "VALP" addon... And viceversa, if I would launch programmatically an addon, how could I find its internal name?

Thank you,
Filippo

The Addons for Visio are afaik not officially documented anywhere. Sometimes you can get lucky because some of the guys working with Visio know a trick or two and post it in their blogs, but I couldn't find anything about the VALP-Addon using google.

I'm not sure that addon still exists even though the shape references it. No validation of the pie sizes is performed. There is no VBA macros of that name as the comment says.
