Switch input language in remote application

Question

Can I switch the input language for another application? Having a process id, thread id, window handle, etc.

Answer 1

Maybe LoadKeyboardLayout and ActivateKeyboardLayout ?

Answer 2

I think this was asked before.

Is there a built-in WinXP / WinXP API for changing Locale (in particular, IME)?

Although it is Windows Embedded, the API is probably the same or similar.
