EventArgs Class Diagram

The following diagram shows how the various event argument classes defined in the Ivi.Visa namespace are related to each other. In addition, it shows the Native Access API for more direct access to underlying (native) VISA C event information. You can reach the native C API only by casting session classes to specific Native Access interfaces, whereas you can use the event argument classes based on VisaEventArgs with all of the event mechanisms commonly used in VISA.NET.
