如何通過流程名稱將焦點移至窗口？

Question

如果我正確理解這個代碼應該捕獲活動窗口並保持焦點。 concentr.exe是進程名稱。 如何根據進程名稱爲焦點窗口？

Add-Type @" 
using System; 
using System.Runtime.InteropServices; 
public class UserWindows { 
[DllImport("user32.dll")] 
public static extern IntPtr GetForegroundWindow(); 
} 
"@    
try {    
$ActiveHandle = [UserWindows]::GetForegroundWindow() 
$Process = Get-Process | ? {$_.MainWindowHandle -eq $activeHandle}    
$Process | Select ProcessName, @{Name="concentr.exe";Expression= {($_.MainWindowTitle)}}    
} catch {    
Write-Error "Failed to get active Window details. More Info: $_"    
} 

我也試過

param([string] $proc="Citrix Connection Manager", [string]$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); 
}

我使用這個腳本來做到這一點。修改爲你需要...
