Is there a way to get access to a window handle in windows using WSH, or WMI or similar?

Question

Is there a way to get access to a window handle in windows using WSH, or WMI or similar? I just want to flag a window as always-on-top. Ideally I'd use windows script host for this.

Answer 1

To grab it with WSH, you can use the COM DLL found in this CodeProject article. Using this, you can then grab a window handle like so:

Set obj = CreateObject("APIWrapperCOM.APIWrapper")
winHandle = obj.FindWindow("test.txt - Notepad")

This is also very easy in PowerShell.

example:

(Get-Process powershell).MainWindowHandle

This grab's the window handle of the PowerShell process.

Although if your main goal is to make a window topmost, there are many programs for this such as DeskPins:

I know it's a massive necro and pardon if it was solved already, but I've been struggling with it for some time now and here's a really simple solution I wrote:

function WinExist($winTitle, $instance = 0)
{
    $h = Get-Process | Where-Object { $_.MainWindowTitle -match $winTitle } | ForEach-Object { $_.MainWindowHandle }
    if ( $h -eq $null )
    {
        return 0
    }
    else
    {
        if ( $h -is [System.Array] )
        {

            $h = $h[$instance]
        }
        return $h
    }
}

Returns "0" if window wasn't found, or the window handle. If found more windows matching the $winTitle string it returns the $instance number (0 means first window, 1 second, etc.).

Example:

# WinExist str_WindowTitle int_WindowNumber
# returns the handle of second notepad window (if more than 1 opened)
$hwnd = WinExist "notepad" 1

I just want to flag a window as always-on-top.

have a look at Eusing's Auto Window Manager. not only can you automatically keep all windows you specify always on top but you can also apply transparency effects from 0% (fully transparent) to 100% (solid).

Auto Window Manager is freeware.
