How do I extract data from an ActiveX control

[wineboy]

I am using a basic frequency counter. The counter comes with a user manual (attached) and a VB example (attached). I do not understand how to use the event callback node in Labview 7.0, it is rather confusing wiht this application.

You example could not be loaded. You need to include the complete VB example code (zip the whole directory).
