将 VBS 嵌入 PowerShell [英] Embed VBS into PowerShell

问题描述

我们在这里有一个应用程序可以将数据转储到 CSV 文件中，然后由另一个脚本使用.在应用程序的前一个迭代中，其中一列是user_name"并包含用户 ID.那仍然存在，但它现在将_company"附加到用户 ID，因此现在列中的用户 ID 不再是tim"，而是tim_company".我们正在考虑剥离公司，我认为最好的方法是将一些 VB 作为函数嵌入到现有脚本中，就像这个网站建议的那样:http://www.out-web.net/?p=130.

We have an application here that dumps data into a CSV, which is then used by another script. In the previous iteration of the application, one of the columns was "user_name" and contains user IDs. That is still there, but it now appends "_company" to the user ID, so instead of the user ID "tim" it is now "tim_company" in the column. We are looking to strip the company off, and I thought the best way would be to embed some VB into the existing script as a function, like this site suggested: http://www.out-web.net/?p=130.

这是我尝试添加的内容:

This is what I've tried to add:

function Load-VbsCode{
    param(
        $Code = $(throw "No VBS code specified.")
    )

    # Convert an array of multiple text lines to a string
    $vbsCode = [string]::Join("`n", $Code)

    $vbs = New-Object -ComObject 'MSScriptControl.ScriptControl'
    $vbs.Language = "VBScript"
    $vbs.AddCode($vbsCode)
    $vbs.CodeObject
}
# pass the entire vbs file to Load-VbsCode
$vbs = Load-VbsCode $(Get-Content .\ReplaceData.vbs)
# Ready to use the Removenavient function
$c = $vbs.RemoveData

.vbs 只是删除/替换数据，如下所示:

The .vbs is just to remove/replace data as shown here:

Function Removedata
    Const FromValue = "_company"
    Const ToValue = ""

    Dim objExcel : Set objExcel = CreateObject("Excel.Application")
    'objExcel.Visible = True
    Set objWorkbook =  objExcel.Workbooks.Open("D:\Location\JunkData.csv")
    Dim objWorksheet : Set objWorksheet = objWorkbook.Worksheets(1)
    'Dim objRange : Set objRange = objWorksheet.UsedRange

    objWorksheet.Cells.Replace FromValue, ToValue

    objExcel.DisplayAlerts = False
    objExcel.Save
    objExcel.Quit
End Function

我收到此错误:

我不会VB，也不知道如何在PS中调用VBScript.我读到这可能是一个丢失的 DLL，但我更有可能相信我没有调用我应该调用的东西.有什么想法吗?

I don't know VB, and I don't know how to call VBScript in PS. I read this might be a missing DLL, but I'm more likely to believe I'm not calling something I should be calling. Any ideas?

推荐答案

我和其他人一样，因为我认为你不必要地使事情复杂化.如果您只想剥离公司，那么import-csv 并循环进行更改.

I'm with everyone else in that I think you are unnecessarily complicating things. If all you want to do is strip the company off then import-csv and loop to make your changes.

给定保存在文件中的示例 CSV

Given the sample CSV saved in file

user_name,first_name,last_name
lrivera0_company,Lawrence,Rivera
tlawrence1_company,Theresa,Lawrence
rboyd2_company,Roy,Boyd
cperry3_company,Christine,Perry
jmartin4_company,Jessica,Martin

针对它运行以下代码.

$filepath = "d:\temp\text.csv"
$toReplace = "_company"
(Import-Csv $filepath) | ForEach-Object{
    $_.User_Name = ($_.User_Name).Replace($toReplace,""); $_
} | Export-CSV $filepath -NoTypeInformation

这会将文件作为 PowerShell 对象读取.对于每条记录，我们通过删除_company"来更新user_name(警告是我希望你没有像_company_company"这样的帐户).使用 $_ 将更新的记录推回到管道中，然后再推到原始文件中.请像我一样先用虚拟数据测试这个.

That will read the file as a PowerShell object. For every record we update the user_name by removing "_company" (caveat being I hope you don't have accounts with that in there already like "_company_company"). Use $_ to push the updated record back into the pipe and out again to the original file. Please test this with dummy data first like I did.
