Is there a way to detect a specific Visio master used in any diagr

[hellothere]

Good morning everyone,

I'm creating a Visio add-on software in C#. I would like to read Visio
diagrams and recognize if the user have used a very specific master shape
that comes with Visio.

For example, I would like to be able to say: "Aha! the user have used 5
instances of the On-page reference shape." for a diagram draw in the US,
France or Australia.

By the way, I'm currently comparing a shape's master.NameU to a predefined
string like "On-page reference" for example. This works now, but I'm worried
about what will happen if the user uses another stencil that also has a shape
called exactly by that same name. I have also tried master.BaseID, but the
value of that property changes from one diagram to another, even for the same
master shape...


Help! Mayday, mayday! Any comments or answers will be greatly appreciated,
so I thank you in advance.


Have a nice week end!

You might add a user defined section to the master shape and put a unique
note there to know where the shape comes from.

Hi JuneTheSecond,

Thank you for the tip, I'll add such custom properties and sections to
masters of the stencil that I'm going to build.

However, I can't possibly ask every user to create such custom section in
every master's shapesheet before he drags and drops a shape from his library
of stencils. I mean, I need to find a property that is shared by, but unique
to, all
"Business Process" => "Basic Flowchart shapes" => "On-page reference" shape,
for anyone in the world.

Thanks again JuneTheSecond, I just hope someone knows if such property (or
anything equivalent) exists!
