Storing object reference

[Shahzad Godil]

Our solution required a very complex property object, which Visio own custom
property cannot fullill. For this, we have created a class which will store
data of that particular shape. I want to store class object of my data
class somewhere in shape property. I was using one another tool which has
property call "TagVariant" which we using for store a variant or object
reference. Is there any way in shape class where we can store a class
object reference.

Thanks
