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

I'm just curious - why do you want to do this? Are you writing a better UI for picking language?Michael Kohne– Michael Kohne2009-05-04 11:33:01 +00:00Commented May 4, 2009 at 11:33

No, I have a scenario where user can add a new language keyboard but the application does not provide him facility to get into control panel. It's an Win Embedded application with only the App UI and nothing else.LogInIssue– LogInIssue2009-05-04 11:40:22 +00:00Commented May 4, 2009 at 11:40

I'm kinda looking for the same thing - a programmatic method to change the input locale in a system-wide manner, or to any application I choose...Shalom Craimer– Shalom Craimer2009-05-04 16:52:50 +00:00Commented May 4, 2009 at 16:52

Nobody knows. Obviously, tray icon can change language systemwide.
Not tried myself, according to documentation SetLocaleInfoA (or ...W variant – undecorated alias if relying on UNICODE setting) does the job on system level.
Don't forget to broadcast the WM_SETTINGCHANGE message as documented.

Late reply for late readers...
i managed to do it with keyboard events & shortcut assignment.
- go to "text services and input language" (that's how it's called windows 7 control panel)
- 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.
- 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:
