public event EventHandler<VisaEventArgs> SystemFailure
public: event EventHandler<VisaEventArgs^>^ SystemFailure
The event handler receives an argument of type VisaEventArgs containing data related to this event. The following VisaEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| CustomEventType | A value that uniquely identifies an implementation-specific event type. |
| EventType | The VISA.NET standard event type. |
Multiple event handlers may be registered for this event.
When a calling program registers an event handler, it is possible that the event handler might be called before the call to register the event handler returns. In this case, the event handlers registered for an event are executed before the return of the event handler registration.
Client programs should either use the event-related methods DisableEvent, DiscardEvents, EnableEvent, and VisaSession.WaitOnEvent (any overload) with the appropriate eventType, -or- the .NET events which are defined individually for each event stype in the ession class to which they apply. If a calling program uses both mechanisms at the same time, it will receive the event twice, once for each mechanism.
