使用vbs獲取雅虎匯率

Function bytes2bstr(vin)

  strreturn = ""

  for i = 1 to lenb(vin)

    thischarcode = ascb(midb(vin,i,1))

    if thischarcode < &h80 then

      strreturn = strreturn & chr(thischarcode)

    else

      nextcharcode = ascb(midb(vin,i+1,1))

      strreturn = strreturn & chr(clng(thischarcode) * &h100 + cint(nextcharcode))

      i = i + 1

    end if

  next

  bytes2bstr = strreturn

End Function

Function GetURL(url)

  Set Retrieval = CreateObject("Microsoft.XMLHTTP")

  With Retrieval

    .Open "GET", url, False

    .Send

    GetURL = bytes2bstr(.responsebody)

    if len(.responsebody)<2 then

      strContent = "遠(yuǎn)程通訊故障！"

      Call LogToFile(strContent,1)

    response.end

    end if

  End With

  Set Retrieval = Nothing

End Function

  MsgBox huilv

End if
