Syntax

'Declaration
Public MustOverride Sub ReadValue ( _
    sequenceNumber As Integer, _
    timeout As Integer _
)

public abstract void ReadValue (
    int sequenceNumber,
    int timeout
)

public:
virtual void ReadValue (
    int sequenceNumber, 
    int timeout
) abstract

public abstract void ReadValue (
    int sequenceNumber, 
    int timeout
)

public abstract function ReadValue (
    sequenceNumber : int, 
    timeout : int
)

Parameters

  • sequenceNumber
    Sequence number.
  • timeout
    The maximum waiting time (in milliseconds) until the response is received from the device. WaitForever can be specified.

Remarks

Electronic Value is read from the card specified by SequenceNumber on demand.

When timeout is WaitForever, a time-out never occurs, and the service waits indefinitely until it receives a response from the device.
