Property

If you change the value of a property, in an object which
has been passed ByVal, does the property persist after
the call?

If the object is an instance of a reference type, it will persist.

Hi Sandy,

Could you show us some code? It sounds as if you need a bit of explanation
about Properties and ByVal, etc. It's difficult to say anything until we know
where you're coming from on this.

Regards,
Fergus

You need to be more specific. Are you asking whether the value of the object property changes with
respect to the calling procedure? Is this an in-process or out-of-process (marshaled) call? What
kind of object are you passing?
