我找到了这个脚本,似乎无法弄清楚为什么在尝试创建文件C:\IPSecWeights.xls时会抛出错误。

到目前为止,我遇到的问题是:

Set objWorkbook = objExcel.Workbooks.Open(FileLoc)

我收到一条错误,指出无法找到该文件。如何重写我的代码来解决这个问题?

Const ForReading = 1
Const ForWriting = 2
Const ForAppending = 8
Dim objFSO,objFile
Dim arrLines
Dim strLine
Dim objExcel,objWorkbook
Dim FileLoc
Dim intRow
Dim objDictionary

FileLoc = "C:\IPSecWeights.xls"

Sub ExcelHeaders()
    Set objRange = objExcel.Range("A1","G1")
    objRange.Font.Size = 12
    objRange.Interior.ColorIndex=15

    objexcel.cells(1,1)="Filter Name"
    objexcel.cells(1,2)="Source"
    objexcel.cells(1,3)="Destination"
    objexcel.cells(1,4)="Source Port"
    objexcel.cells(1,5)="Destination Port"
    objexcel.cells(1,6)="Protocol"
    objexcel.cells(1,7)="Direction"
End Sub

Function RegExFind(strText,strPattern)
    Dim regEx
    Dim match, Matches
    Dim arrMatches
    Dim i : i = 0
    Set regEx = New RegExp
    regEx.IgnoreCase = True
    regEx.Global = True
    regEx.Pattern = strPattern

    Set matches = regEx.Execute(strText)
    ReDim arrMatches(Matches.Count)
    For Each match In Matches
        For Each SubMatch In match.Submatches
            arrMatches(i) = Submatch
            i = i + 1
        Next
    Next
    RegExFind = arrMatches
End Function


Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(WScript.Arguments(0),ForReading)

Set objExcel = CreateObject("excel.application")
Set objWorkbook = objExcel.Workbooks.Open(FileLoc)

objExcel.Visible = True

For i = 0 To UBound(arrPolicy)
    objExcel.Cells(introw,1) = arrPolicy(i)
    objExcel.Cells(introw,2) = arrSRCAddr(i)
    objExcel.Cells(introw,3) = arrDSTAddr(i)
    objExcel.Cells(introw,4) = arrSRCPort(i)

我怀疑“找不到文件”是一个有点误导性的错误消息。也就是说,您的实际问题是文件系统权限,但VBScript顽固地报告这是“未找到文件”而不是更明智的错误。

据推测,该脚本在早期版本的Windows中运行良好,但您现在正在安装Vista或更高版本的计算机上进行尝试,这会引入一系列额外的安全功能和写保护。 User Account Control (UAC)不允许应用程序或脚本写入硬盘的根级别。

这当然不应该是一个问题,因为合法的应用程序不需要篡改硬盘根级别或共享系统文件夹(如C:\Windows)中的文件,但偶尔会出现问题在测试期间。

将脚本中的文件路径更改为您可以保证具有读/写权限的文件路径,例如“我的文档”文件夹。对于部署,您不应该对文件系统路径进行硬编码。请使用FileSystemObject的{​​{3}}来检索路径。
