Powershell新人

问题描述 投票:-1回答:3

我是Powershell的新手,如果我的问题听起来很愚蠢,请原谅我。我从Yuri Posidelov找到以下脚本,我对该脚本进行了调整,以激活一个进程并显示窗口并发送击键以关闭该进程,效果很好。但是,如果有两个名称相同的进程会失败,任何人都可以帮我解决这个问题。

尤里·波塞德洛夫的地方代码

param([string] $proc="SBDDesktop", [string]$adm)

cls


Add-Type @"

  using System;

  using System.Runtime.InteropServices;

  public class WinAp {

     [DllImport("user32.dll")]

     [return: MarshalAs(UnmanagedType.Bool)]

     public static extern bool SetForegroundWindow(IntPtr hWnd);


     [DllImport("user32.dll")]

     [return: MarshalAs(UnmanagedType.Bool)]

     public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

  }


"@

$p = Get-Process |where {$_.mainWindowTItle }|where {$_.Name -like "$proc"}


if (($p -eq $null) -and ($adm -ne ""))

{

    Start-Process "$proc" -Verb runAs

}

elseif (($p -eq $null) -and ($adm -eq ""))

{

    Start-Process "$proc" #-Verb runAs

}

else

{

    $h = $p.MainWindowHandle


    [void] [WinAp]::SetForegroundWindow($h)

    [void] [WinAp]::ShowWindow($h,3);


    $wshell = New-Object -ComObject wscript.shell;

    #$wshell.SendKeys('~')

    $wshell.SendKeys('%fx')

    sleep 1

    $wshell.SendKeys('N')


}


#|format-table id,name,mainwindowtitle –AutoSize

# static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

# powershell.exe -windowstyle hidden -file *.ps1 -adm "a"

问题是,如果行$p = Get-Process |where {$_.mainWindowTItle }|where {$_.Name -like "$proc"}有多个进程,它将创建一个类型为array的对象。否则,它将创建System.ComponentModel.Component类型的对象。您可以使用以下方法进行测试:

$p.GetType()

为了补偿这一点,即使该数组中只有一个元素,您也可以在数组中执行代码foreach处理:

...
[array]$array = Get-Process |where {$_.mainWindowTItle }|where {$_.Name -like "$proc"}

foreach ($p in $array){


    if (($p -eq $null) -and ($adm -ne ""))

    {

        Start-Process "$proc" -Verb runAs

    }

    elseif (($p -eq $null) -and ($adm -eq ""))

    {

        Start-Process "$proc" #-Verb runAs

    }

    else

    {

        $h = $p.MainWindowHandle


        [void] [WinAp]::SetForegroundWindow($h)

        [void] [WinAp]::ShowWindow($h,3);


        $wshell = New-Object -ComObject wscript.shell;

        #$wshell.SendKeys('~')

        $wshell.SendKeys('%fx')

        sleep 1

        $wshell.SendKeys('N')


    }


    #|format-table id,name,mainwindowtitle –AutoSize

    # static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    # powershell.exe -windowstyle hidden -file *.ps1 -adm "a"

}

[如果有多个窗口句柄,请执行循环:

$processList = [object[]]@( Get-Process |where {$_.mainWindowTItle }|where {$_.Name -like "$proc"} )

foreach( $p in $processList ) {

    if (($p -eq $null) -and ($adm -ne "")) {
        Start-Process "$proc" -Verb runAs
    }
    elseif (($p -eq $null) -and ($adm -eq "")) {
        Start-Process "$proc" #-Verb runAs
    }
    else {

        $h = $p.MainWindowHandle

        [WinAp]::SetForegroundWindow($h) | Out-Null

        [WinAp]::ShowWindow($h,3) | Out-Null


        $wshell = New-Object -ComObject wscript.shell;

        #[void]$wshell.SendKeys('~')

        [void]$wshell.SendKeys('%fx')

        sleep 1 | Out-Null

        [void]$wshell.SendKeys('N')
    }
}

Get-Process将返回符合您条件的所有进程,这意味着它将把多个对象返回到变量$p

所以您需要遍历它们,您可以简单地使用foreach循环

foreach($process in $p){
    if (($process -eq $null) -and ($adm -ne ""))

    {

        Start-Process "$proc" -Verb runAs

    }

    elseif (($$process -eq $null) -and ($adm -eq ""))

    {

        Start-Process "$proc" #-Verb runAs

    }

    else

    {

        $h = $process.MainWindowHandle


        [void] [WinAp]::SetForegroundWindow($h)

        [void] [WinAp]::ShowWindow($h,3);


        $wshell = New-Object -ComObject wscript.shell;

        #$wshell.SendKeys('~')

        $wshell.SendKeys('%fx')

        sleep 1

        $wshell.SendKeys('N')


    }
