Muli-language problem

How to change the LangDLL::LangDialog language along with the Operating System language.
The LangDialog is English,How it can vary along with the OS
language.
For Example ,My OS is Simply Chinese,The LangDialog is in simply Chinese; My OS is French,The LangDialog is in French;
Thanks very much for your replay,Best regands for you!

IMHO for this you need no LangDialog. The OS GUI language is determined and used in the istaller if Language is embedded in your installer.

If the user can use the OS in current language he/she 99.99% sure also can read th language and thus the language of the installer.

Thanks,
I think there are two ways to fix this problem:
1) Do not use the LangDialog
2) use the LangDialog,but use System API to judge the OS language,then change the language of the LangDialog

Is it right?

Right.
