Turns the tag into a read-only mode.

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

Syntax

'Declaration
Public MustOverride Sub LockTag ( _
    tagId As Byte(), _
    timeout As Integer, _
    password As Byte() _
)

public abstract void LockTag (
    byte[] tagId,
    int timeout,
    byte[] password
)

public:
virtual void LockTag (
    array<unsigned char>^ tagId, 
    int timeout, 
    array<unsigned char>^ password
) abstract

public abstract void LockTag (
    byte[] tagId, 
    int timeout, 
    byte[] password
)

public abstract function LockTag (
    tagId : byte[], 
    timeout : int, 
    password : byte[]
)

Parameters

  • tagId
    The ID of the tag it is locking.
  • timeout
    Allowed execution time, in milliseconds, before the method fails and a time-out ErrorEvent event is sent to the application. If WaitForever the service waits as long as needed until either the operation is complete or an error occurs.
  • password
    Authorized key for reader that might be required for this operation, null if not applicable.

Remarks

Makes ID and UserData fields non-writable. If invoking this method with CapLockTag property being false, an exception is thrown.

This method is always performed asynchronously and the OutputId property will be set on a successful start plus an OutputCompleteEvent event or ErrorEvent event will be raised to indicate completion.

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.
