Hi,
I'd like to store some string value persistently, and recall and use the string value as a shape data of visio.
I thought Memory file could be an option, because you can store strings to Memory file, but don't know how you can recall and apply it as a shape data.
Any good way to achieve that ?
You can store values in view or element properties, and use these in your drawing using the [proerpty:propertyname] placeholder.

Not directly.
To achieve this, you’d need to trigger an automation script from the visual, which sets the property value.
On the other hand, is there a way to store from a drawing to a property value?
