Get UI Information for Processes

Get-ProcessInfoUI.ps1

<# PowerShell.Com

PowerShell can use UIAutomation calls to find out useful UI information about any process.

You can find out whether a process accepts keyboard input, whether it is currently visible
(and what its window dimensions are), and whether it is a native Win32 application
or uses WPF--among other things.

Here is an example that examines two processes: the PowerShell window, and a minimized Notepad:

#>

#requires -Version 2 
function Get-ProcessInfoUI($Process)
{
  foreach ($proc in $Process)
  {
    Add-Type -AssemblyName UIAutomationClient
    [System.Windows.Automation.AutomationElement]::FromHandle($proc.MainWindowHandle).Current |
    Select-Object -Property Name, HasKeyboardFocus, IsOffscreen, BoundingRectangle, NativeWindowHandle, ProcessId, Orientation, FrameworkId
  }
}
 
# get current PowerShell process: 
$ise = Get-Process -Id $pid
# start new Notepad and wait until loaded: 
$notepad = Start-Process notepad -WindowStyle Minimized -PassThru
$null = $notepad.WaitForInputIdle()
 
# get UI information for these processes 
Get-ProcessInfoUI $ise, $notepad | Out-GridView -Title 'UI Information'
