Is it possible to switch input language for another application? Having application's process ID, thread ID, window handle etc.

Answer 1

I think it's been asked before.

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

Answer 2

Maybe LoadKeyboardLayout and ActivateKeyboardLayout ?
