Get Labview class from the VI through ACTIVEX

[VinhPN]

Hi,

I have been using OOP in Labview. My VI pass a Labview class object from one method to another.
I am trying to call this VI through ActiveX interface in Python.
However, I can't figure out how to get the class object from a VI. I only know of this method called : getcontrolvalue().
Is there a way to get the object from a OOP VI and pass it to another OOP VI ?

Warm regards,
Thank you.
