English application on chinese Vista

[Frederic Forjan]

Hello,

We have an application in C++/MFC which run very well on Windows XP.
We are able to run a chinese version of our application on a english
Windows XP.
We are able to run a english version of our application on a chinese
Windows XP.

But with exactly the same code, the english version of our application
on a chinese Windows Vista does not work :
the font seems to always stay to the chinese 'simsun'.

Nothing change if we try to set our targetted font for english in our
resources or use WM_SETFONT Win32 message - we are only able to change
the font size if we use this WM_SETFONT.(but never the font face!)

Since all our MFC dialog are designed with our targetted font (MS Sans
Serif), the dialog is completely broken.
Do you have some ideas ?

Best regards,
