c - 如果从 C 程序执行，Powershell 脚本不起作用？

Question

我有一个 powershell 脚本，如果我从管理员 powershell 运行它，它可以正常工作。但是，如果我在 c 程序中调用 powershell 脚本，以管理员身份运行，使用 system() 函数，它的某些部分不起作用。更具体地说，复制 unattend.xml 和 sysprep.exe 命令。我已经发布了 powershell 脚本和 c 程序脚本。我怎样才能让它发挥作用？

POWERSHELL 脚本:

#Set working directory to scripts location.
$scriptpath = $MyInvocation.MyCommand.Path
$Switcheroo = Split-Path $scriptpath
Set-Location $Switcheroo
#Set error options
$Error.clear()
$ErrorActionPreference = “Inquire”

Write-Host "Running part 2."
#1
& "DISKPART" /s $Switcheroo\DskPrtRmv.txt
TIMEOUT /T 3

#2
if ($? -eq "True")
{
    Copy-Item $Switcheroo\unattend.xml $env:windir\System32\Sysprep
    TIMEOUT /T 3 

    #3
    if ($? -eq "True")
    {
        SCHTASKS /Delete /TN "Switcheroo" /f
        TIMEOUT /T 3
    }
    elseif ($? -ne "True")
    {
        Write-Host Failed to copy unattend.xml
        exit (22)
    }

        #4
        if ($? -eq "True")
        {
            rm log.txt
            TIMEOUT /T 3
        }
        elseif ($? -ne "True")
        {
            Write-Host Failed to delete the schedued task
            exit (32)
        }

            #5
            if ($? -eq "True")
            {
                & "$env:windir\System32\Sysprep\sysprep.exe" /generalize /oobe /shutdown /unattend:unattend.xml
            }
            elseif ($? -ne "True")
            {
                Write-Host Failed to remove the log.txt
                exit (42)
            }
                #6
                if ($? -ne "True")
                {
                    Write-Host Sysprep failed.
                    exit (52)
                }
}
elseif ($? -ne "True")
{
    Write-Host Failed to run DskPrtRmv
    exit (12)
}

您正在测试的计算机上的操作系统架构是什么？

当你编译你的 C 程序时，你的目标是 32 位还是 64 位 exe？

您的问题可以解释为您的操作系统是 64 位，而您的程序是 32 位，因此它执行 32 位版本的 PowerShell，这会产生一些问题。

如果是这样，您可以解决从 32 位 C exe 使用生成 64 位 PowerShell 的问题。
