Updates the key information in the device.

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

Syntax

'Declaration
Public MustOverride Function UpdateKey ( _
    data As Integer, _
    obj As Object _
) As EVRWResult

public abstract EVRWResult UpdateKey (
    int data,
    Object obj
)

public:
virtual EVRWResult UpdateKey (
    int data, 
    Object^ obj
) abstract

public abstract EVRWResult UpdateKey (
    int data, 
    Object obj
)

public abstract function UpdateKey (
    data : int, 
    obj : Object
) : EVRWResult

Parameters

  • data
    Data depends on implementation.
  • obj
    Object depends on implementation.

Remarks

If the device has the function to the key information, it is supported.

The content of processing and the content of the parameter depend on the implementation.

For consistency, a Service must always fire at least one TransitionEvent with an incomplete progress completion percentage (i.e. a percentage between 1 and 99), even if the device cannot physically report the progress of the process. If the process completes successfully, the Service must fire a TransitionEvent with a progress of 100. These Service requirements allow applications using this method to be designed to always expect some level of progress notification.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread-safe. Any instance members are not guaranteed to be thread-safe.
