ControllerInCharge Event (GpibInterfaceSession)



Keysight.Visa Namespace > GpibInterfaceSession Class : ControllerInCharge Event
Occurs when the GPIB controller has gained or lost CIC (controller in charge) status.
Syntax
'Declaration
 

Public Event ControllerInCharge As EventHandler(Of GpibControllerInChargeEventArgs)
'Usage
 

Dim instance As GpibInterfaceSession
Dim handler As EventHandler(Of GpibControllerInChargeEventArgs)
 
AddHandler instance.ControllerInCharge, handler
public event EventHandler<GpibControllerInChargeEventArgs> ControllerInCharge
public:
event EventHandler<GpibControllerInChargeEventArgs^>^ ControllerInCharge
Event Data

The event handler receives an argument of type GpibControllerInChargeEventArgs containing data related to this event. The following GpibControllerInChargeEventArgs properties provide information specific to this event.

PropertyDescription
CustomEventType A value that uniquely identifies an implementation-specific event type. (Inherited from Ivi.Visa.VisaEventArgs)
EventType The VISA.NET standard event type. (Inherited from Ivi.Visa.VisaEventArgs)
IsControllerInCharge True if the controller for the GPIB interface is in charge.  
Remarks

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 VisaSession.DisableEvent, VisaSession.DiscardEvents, VisaSession.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.

Requirements
