How to get the language id in MFC

If we want to know which language id is we are using now,
Some of you may asked this question. Especially, your program have to support
multi-language.

Below code is the sample code:

WORD GetSystemLanguageID()
{
return LANGIDFROMLCID(::GetSystemDefaultLCID());
}

After calling this function, it's will return one WORD datatype information,
For example English : 0x0409, Traditional Chinese : 0x0404

From now, I believe that you should understand how to use the result.

Cheers.
