vbscript - How to find the window Title of Active(foreground) window using Window Script Host

Question

I want to find the title of the window which is currently active(having focus) using Window Script Host(WSH) because I want my WSH script to Sendkeys only If the desired window is active.

Note* I am not in a condition to use the alternative i.e activating the desired window before invoking sendkeys.

Any help is appreciated.

Short answer: You can't. At least not without writing a COM wrapper for the relevant Windows API calls.

Can't you just use AppActivate and check the result?

Set oShell = CreateObject("WScript.Shell")
If oShell.AppActivate "Untitled - Notepad" Then
  oShell.SendKeys "Hello, world!"
End If

Long answer: To get the active window title, you need to call the Windows API GetWindowText function and pass the GetForegroundWindow() handle. VBScript and Windows Script Host don't support Windows API calls, so you'll need to write a COM wrapper around these functions, that you can then use in your script. Here're examples:
