How to detect language changes?

[Siegfried Heintze]

I need to redundantly write C++ and C# programs to
(1) determine the input language (german, french, english...)
(2) determine changes in the input language (preferably a delegate rather
than polling!)

Can anyone guide me to the proper functions to call?
Thanks,

There are no pre-existing functions for either item. In general you could
try to split the text into words, and look for occurrances of the most common
words in each language. Search for "the", "of", "a" and you likely have
English. Search for "der", "die", "das", "ob", "einen", and you likely have
German.

It won't be easy...

If I run the program intl.cpl, I can change the keyboard type.

How is intl.cpl implemented?

How can I write a C# program to determine when someone has run intl.cpl and
changed the keyboard langauge?
Thanks,
Siegfried

I found it: I need to intercept WM_SETTINGSCHANGE. There is a sample program
in .NET Internationalization by Smith-Ferrier.

Now I have another question: how can I change to a DVORAK keyboard and
detect that change?

Thanks
Siegfried

Letter frequencies can also help.

So you are not looking to detect what language the text written
is in but just detect the windows language setting ?
