Windows has a strange way to show locales.
This site is in German, but it shows many locales (also in Linux and HPUX):
lua.gts-stolberg.de/os.php
In my PC, for example, it shows "Spanish_Spain.1252". It could have been "es_ES.ISO885915", but that's not my O.S.
I remember to make a chime clock 6 months ago (
original link). Using that code and several wave files from an old software called "Da La Hora" (~"Give Time") delivered in a PC magazine, I created a Spanish version of the chime.
If you can't find a way to run another language within the 3rd party app, I could upload it. What do you think?
