Hello optobionics,
Assuming you are using LabVIEW 7.0 or 7.1, there are two shipping examples that deal with registering callback functions for ActiveX events: �ActiveX Event Callback for Excel.vi� and �ActiveX Event Callback for IE.vi�. This will give you some idea of what to do. It is actually up to the program being called through ActiveX as to whether the events are available or not. The following KnowledgeBase also discusses using callback functions.
Migrating from the ActiveX Event VIs to Using the Register Event Callback NodeIf none of these suggestions help, or if I�m not correctly understanding your issue, please reply with comments or answer
s to the discussion above and any additional information that may help, and I�ll be happy to look further into it.
Have a nice day!
