Syntax

'Declaration
Public MustOverride Event DataEvent As DataEventHandler

public abstract event DataEventHandler DataEvent;

public: abstract event DataEventHandler^ DataEvent;

public abstract  void add_DataEvent(DataEventHandler handler);
public abstract  void remove_DataEvent(DataEventHandler handler);

In JScript, you can handle the events defined by a class, but you cannot define your own.

Remarks

The DataEventArgs.Status property is divided into four bytes. Depending on the Event Type (located in the low word), the remaining two bytes contain additional data.

The high word, low byte contains additional data depending on the event type. When the event type is DataEventKey (replaces BB_DE_KEY), the low byte of the high word contains the logicalKey code for the key pressed on the bump bar unit. The logicalKey value is device independent; it has been translated by the service object from its original hardware specific value. Valid ranges are 0-255.

The high word, high byte value is unused.

The EventUnitId property is updated before delivering the event.
