Powershell 在控制台而不是对话框中显示 Regsvr32 结果

Question

我搜索过但没有找到任何答案。
任务是使用 Powershell ps1 注册一个 dll，然后是其他行的脚本。我不想被对话框打断，所以添加了 /s 参数。但是现在无论成功还是失败，结果信息都被忽略了。我希望结果显示在控制台中。但是怎么办？

Answer 1

使用 Start-Process -PassThru 启动 regsvr32.exe /s 并检查 ExitCode 属性:

$regsvrp = Start-Process regsvr32.exe -ArgumentList "/s C:\path\to\your.dll" -PassThru
$regsvrp.WaitForExit(5000) # Wait (up to) 5 seconds
if($regsvrp.ExitCode -ne 0)
{
    Write-Warning "regsvr32 exited with error $($regsvrp.ExitCode)"
}

这是一个更完整的完整 powershell cmdlet，支持管道。

function Register-Dll
{
    <#
    .SYNOPSIS
        A function that uses the utility regsvr32.exe utility to register a file
    .PARAMETER Path
        The file path
    .PARAMETER Unregister
        when specified, unregisters instead of registers
    #>
    [CmdletBinding()]
    param (
        [ValidateScript({ Test-Path -Path $_ -PathType 'Leaf' })]       
        [Parameter(Mandatory=$true,ValueFromPipeline=$true,ValueFromPipeLineByPropertyName=$true)]
        [Alias("FullName")]
        [string[]]$Path,
        [Alias("u")]
        [switch]$Unregister
        )
    begin {
        if ($Unregister)
        {
            $regflag = "-u "
        }
        else
        {
            $regflag = ""
        }
        [int]$NumFailed=0
        $RegExitCodes = @{
            0="SUCCESS";
            1="FAIL_ARGS - Invalid Argument";
            2="FAIL_OLE - OleInitialize Failed";
            3="FAIL_LOAD - LoadLibrary Failed";
            4="FAIL_ENTRY - GetProcAddress failed";
            5="FAIL_REG - DllRegisterServer or DllUnregisterServer failed.";
        }
    }
    process {
        foreach ($p in $path)
        {
            try
            {
                $regsvrp = Start-Process regsvr32.exe -ArgumentList "/s $regflag <code>$p</code>" -Wait -NoNewWindow -PassThru

                if($regsvrp.ExitCode -ne 0)
                {
                    $NumFailed++
                    Write-Error "regsvr32 $regflag for $p exited with error $($regsvrp.ExitCode) - $($RegExitCodes[$regsvrp.ExitCode])"
                }
            } catch {
                $NumFailed++
                Write-Error $_.Exception.Message
            }
        }
    }
    end {
        if ($NumFailed -gt 0)
        {
            if ($Unregister)
            {
                $mode = "unregister"
            }
            else
            {
                $mode = "register"
            }
            Write-Error "Failed to $mode $NumFailed dll's, see previous errors for detail"
        }
    }
}

用法：

function Register-MyAppDll
{

    param(
        [Parameter(Mandatory=$true,ParameterSetName="Both")]
        [switch]$ReRegister,
        [Parameter(Mandatory=$true,ParameterSetName="UnregisterOnly")]
        [Alias("u")]
        [switch]$UnRegister,
        [Parameter(Mandatory=$true,ParameterSetName="RegisterOnly")]
        [Alias("r")]
        [switch]$Register
    )


    $RegOptions = @()
    if ($UnRegister -or $ReRegister) { $RegOptions += @{Unregister=$true} }
    if ($Register -or $ReRegister) { $RegOptions += @{} }

    $dlltoregister = Get-ChildItem "C:\MyApp\bin" -Filter *.dll | where {$_ -notmatch '^interop'}

    foreach ($RegOpt in $RegOptions)
    {
        $dlltoregister | Register-Dll @RegOpt
    }

}


Register-MyAppDll -UnRegister
Register-MyAppDll -Register
Register-MyAppDll -ReRegister

尽情享受吧:)

谢谢贾斯汀！我正在使用这个脚本并且效果很好。

下面这行代码似乎有错别字：

$regsvrp = Start-Process regsvr32.exe -ArgumentList "/s $regflag <code>$p</code>" -Wait -NoNewWindow -PassThru

代码标签不应该在那里。我将其更改为以下内容，并在路径周围添加了转义双引号以支持路径中的空格：

$regsvrp = Start-Process regsvr32.exe -ArgumentList "/s $regflag `"$p`"" -Wait -NoNewWindow -PassThru
