      porem estou tentendo usar ela no vb.net  editor VISUAL STUDIO 2013, aparece o erro conforme a imagem enexo, alguem consegue corrigir esse erro;
      Function crc_ccitt_ffff(strParam As String) As String
              Const CRC_POLY_CCITT As Long = &H1021&
              Const CRC_START_CCITT_FFFF As Long = &HFFFF&
              Dim crc As Long, b() As Byte, c As Long, i As Long, j As Long
              Dim crc_tabccitt(0 To 255) As Long
              For i = 0 To 255
                  crc = 0
                  c = i * 256
                  For j = 0 To 7
                      If (crc Xor c) And 32768 Then
                          crc = (crc * 2) Xor CRC_POLY_CCITT
                      Else
                          crc = crc * 2
                      End If
                      c = c * 2
                  Next j
                  crc_tabccitt(i) = crc
              Next i
                  b = strParam
              crc = CRC_START_CCITT_FFFF
              For i = 0 To UBound(b) Step 2
                  crc = (crc * 256) Xor crc_tabccitt(((crc \ 256) Xor b(i)) And 255)
                  crc = ((crc \ 65536) * 65536) Xor crc
              Next i
              crc_ccitt_ffff = Hex(crc)
          End Function
