How to access parameter handled by ActiveX event

[jules8491]

I am working on a project which is using ActiveX object.
One of this activex object has an event called "void MsgEvent(parameter X, parameter Y)". When this event occurs, it passes some values into the parameter X and parameter Y, but I don´t know how to get back the values of these parameters via labview...are there any possibilities?

I can�t tell you what method or property that can retrieve the X and Y parameters, since I don�t know the API of your ActiveX server. However, you could refer to this KnowledgeBase [broken link removed; article no longer available] for some information on the way to handle ActiveX Events in LabVIEW 7.x.

You should also play with some of the shipping examples like �ActiveX Event Callback for IE.vi�, to get an idea of how the ActiveX Events work.

I hope this answered your question.
