Bringing a Process Window to the Foreground with PowerShell
PowerShell can use Add-Type to access internal Windows API functions. This way, it is easy to bring any process window into the foreground. Here is the function you need:
#requires -Version 2 function Show-Process($Process, [Switch]$Maximize) { $sig = ' [DllImport("user32.dll")] public static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow) [DllImport("user32.dll")] public static extern int SetForegroundWindow(IntPtr hwnd) ' if ($Maximize) { $Mode = 3 } else { $Mode = 4 } $type = Add-Type -MemberDefinition $sig -Name WindowAPI -PassThru $hwnd = $process.MainWindowHandle $null = $type::ShowWindowAsync($hwnd, $Mode) $null = $type::SetForegroundWindow($hwnd) }
To test-drive Show-Process, here is a sample code on how to use it:
# launch Notepad minimized, then make it visible $notepad = Start-Process notepad -WindowStyle Minimized -PassThru Start-Sleep -Seconds 2 Show-Process -Process $notepad # switch back to PowerShell, maximized Start-Sleep -Seconds 2 Show-Process -Process (Get-Process -Id $PID) -Maximize # switch back to Notepad, maximized Start-Sleep -Seconds 2 Show-Process -Process $notepad -Maximize # switch back to PowerShell, normal window Start-Sleep -Seconds 2 Show-Process -Process (Get-Process -Id $PID)
