Re: How to detect language?

I don't like that the software guesses at what I want, so in my 
application there is a preference setting for the language.

This means that even if my OS is English I can run my app (to about 99%) 
in French or German or whatever.

But I can also see the other side that you do want to either default to 
the system setting or just take it over.

I think it is the first two you are interested in, e.g. fr_FR means 
French French dialect were fr_CH would mean French Swiss dialect.

I think the first part is always lower case, but I see you got this below.

If you want to auto detect I think yes, in my case I feed a preference 
setting to SetLang.

See you
