Parametri

  • sampleValue
    Tipo: System.Int32
    An Int32 value that specifies the sample size. The units are dependent on the scan type.
  • recompute
    Tipo: System.Boolean
    A Boolean value that specifies whether to recompute the statistics.If True, the statistics are recomputed.If False, the statistics are not recomputed.
