How to bring focus to window by process name?

Question

If I\'m understanding this correctly this code should capture the active window and keep it in focus. concentr.exe is the process name. How do I bring a window in focus base

Answer 1

I found it:

Param(
    [string] $proc="C:\Program Files (x86)\Citrix\ICA Client\concentr.exe",
    [string] $adm
)
Clear-Host

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"
} else {
    $h = $p.MainWindowHandle
    [void] [WinAp]::SetForegroundWindow($h)
    [void] [WinAp]::ShowWindow($h, 3)
}
