Retreive hWnd without FindWindow?

I swear I was using a built-in VBA function last week to find out if an application was already running before launching it with the shell function.
The problem is I've lost that work and I can't remember what the function was called.

It's not FindWindow

And as I recall it was a simple built-in VBA function that returned the hWnd of a window as long, by any portion of the application's caption.

That is, it would return a hWnd for the application "Mainframe Session 3 - Microsoft Internet Explorer" if you did function("mainframe session 3")

All I really need to do is find out if an application is already running based on the title bar text, if it is make it active, if it isn't launch it and make it active.

no it was a function you can call directly in vba.

using findwindow in a module doesn't appear to work with only part of a caption

It won't -- you have to have an exact match.

so I know I can activate an app with a partial title string using AppActivate(), is there a comparable function to retreive a handle or title string from a partial title string?
