Win API for changing input language programmatically

问题

I want to change the input language in WinXP to Spanish, programmatically. Is there an API to support that?

Thanks

• LoadKeyboardLayout
• ActivateKeyboardLayout
• GetKeyboardLayout

etc.

i managed to do it with keyboard events & shortcut assignment.

1. go to "text services and input language" (that's how it's called windows 7 control panel)
2. assign keys for the uni-directional language. e.g. "To English", and "To Hebrew". I've chosen Alt-Shift-7 and Alt-Shift-8, because they're rarely used elsewhere.
3. from your app, send the key combination for the appropriate language, when needed.

Note:

if "your app" is an external utility (I wrote mine in Python), then it must NOT invoke a window, otherwise /your-app/ will steal the focus, and will get the language change. in python I solved it by using a GUI-less pyw script filename. (or invoke the script with pythonw.exe)

this article shows how to send keyboard events in python:
