get current language

Greetings...

I've created multi-language installer. In that installer I'm showing some MessageBoxes and I'd like that those boxes shows in the same (to selected for setup's gui) language.
So I want to
-- (minimum) by some way detect current language and show boxes in different language by myself
-- (maximum) make NSIS to do this work.
Is it possible?

Best regards...

See the included example languages.nsi on how to create multilingual messages for all languages supported by your installer.
Note that for messages you might show in function .onInit you need to follow the old, slow, wasteful way which is also described in languages.nsi example.
