Does this help? (You're going to need to unwrap that URL before using
it.)

It refers to the WM_SETICON message, thusly:
An application sends the WM_SETICON message to associate a new large

It's a long time since I tried to access the Windows API from IDL (and
I wasn't hugely successful when I did) but these days I might try
spawning a call to the Windows Scripting Host, which should be
available on later versions of Windows.
