Parameters

• kind
  Defines the parts of the point card that will be cleared (erased).

  1: PrintingArea

  2: MagneticTracks

  3: PrintingAreaAndMagneticTracks

• horizontalPosition
  The horizontal start position for erasing the printing area. The value is in MapMode units if CapPrintMode is true.

• verticalPosition
  The vertical start position for erasing the printing area. The value is in MapMode units if CapPrintMode is true.

• width
  The width used for erasing the printing area. The value is in MapMode units if CapPrintMode is true.

• height
  The height used for erasing the printing area. The value is in MapMode units if CapPrintMode is true.

Remarks

When the CapPrint and CapClearPrint properties are both true, ClearPrintWrite can be used to clear the printing area of a point card. The horizontalPosition, verticalPosition, width, and height parameters define the rectangle to clear. If these parameters are 0, 0, -1, –1 respectively, ClearPrintWrite erases the printing area.

The initialization of the magnetic track data relies on the capability of the device.

ClearPrintWrite may throw a PosControlException exception with the following ErrorCodes:

Value	Meaning
Success	ClearPrintWrite was initiated successfully.
Illegal	The point card reader/writer is not in Point Card Removal mode.
Busy	This operation cannot be performed because asynchronous output is in progress.

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.
