Namespace: Microsoft.PointOfService
Assembly: Microsoft.PointOfService (in microsoft.pointofservice.dll)

Syntax

'Declaration
Public Event ErrorEvent As DeviceErrorEventHandler

public abstract event DeviceErrorEventHandler ErrorEvent

public:
virtual event DeviceErrorEventHandler^ ErrorEvent {
    void add (DeviceErrorEventHandler^ value) abstract;
    void remove (DeviceErrorEventHandler^ value) abstract;
}

/** @event */
public abstract void add_ErrorEvent (DeviceErrorEventHandler value)

/** @event */
public abstract void remove_ErrorEvent (DeviceErrorEventHandler value)

Remarks

Notifies when the error is detected when a method is asynchronously executed, and the state of the control moves to the error state.

Input error events are generated when errors occur while they read the data from a card, directed by ReadValue method. These error events are not delivered until the DataEventEnabled property is set to true to enable correct application sequencing. All error information is put into the applicable properties before this event is delivered.

Output error events are generated and delivered when errors occur during asynchronous output processing. The errors are put into the applicable properties before the events are delivered.
