[Emergency!] How to set system default language by code?

[WizardLee]

Hi, all,


A new feature is required to add to my program today. But I do not have any
idea about it.
The feature should implement these two functions:

1, Select "Install files for East Asia languages" in control panel
applet "Regional and Language Option" in "Language" tabpage, then apply;

2, According to user's selection, choose "Chinese (PRC)" or "Chinese
(TaiWan)" or something else for "Non-unicode application language" in
"Advanced" tabpage, then apply;

This feature may require Windows setup CD and may need reboot.


Thans very very very much!

Sorry. There is something wrong in the question:
The end-user'd better can not see the control panel applet.
I thought there should be some API function like SetSystemDefault... But I
can not find.

Have you looked at SetThreadLocale() and/or _setmbcp()?

 

[WizardLee]

Thank you. But:

SetThreadLocal() only set the settings of "current thread", but not the
system default settings.

_setmbcp() does not take effect.

And, even if some function take effect, how could I know which files should
copy to where? Or is the function tell the end-user?

Not a vc or mfc issue.
Please post in microsoft.public.windowsxp.configuration_manage and microsoft.public.windowsxp.setup_deployment
(assuming your OS is XP)

 

[news.microsoft.net]

But does microsoft.public.windowsxp.configuration_manage or
microsoft.public.windowsxp.setup_deployment discuss program issue?
I am want to set the default language "in my vc++ applicaiton", not manually
in control panel.

I use:

char szLang[32];
char szCountry[32];
char szCodePage[32];

if (GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SENGLANGUAGE,
szLang, sizeof(szLang)) > 0)
{
if (GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SENGCOUNTRY,
szCountry, sizeof(szCountry)) > 0)
{
if (GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_IDEFAULTANSICODEPAGE,
szCodePage, sizeof(szCodePage)) > 0)
{
CString loc;
loc.Format("%s_%s.%s", szLang, szCountry, szCodePage);
setlocale(LC_ALL, loc);
}
}
}

These functions get settings in "Regional Options" tabpage, but not the
"Advanced" tabpage.

For example, in a English WinXP. The UI are english. Install East Asia
support files and set non-unicode encoding to "Chinese(PRC)" in control
panel. These functions will still return English.

I use:

char szLang[32];
char szCountry[32];
char szCodePage[32];

if (GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SENGLANGUAGE,
szLang, sizeof(szLang)) > 0)
{
if (GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SENGCOUNTRY,
szCountry, sizeof(szCountry)) > 0)
{
if (GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_IDEFAULTANSICODEPAGE,
szCodePage, sizeof(szCodePage)) > 0)
{
CString loc;
loc.Format("%s_%s.%s", szLang, szCountry, szCodePage);
setlocale(LC_ALL, loc);
}
}
}

You could try:
LOCALE_IDEFAULTCODEPAGE
or an other value supported by GetLocaleInfo. You can read it on MSDN, I
suppose...

If I understood your question correctly, you want to change the global system
configuration, and this change should persist after your program exits.
Please correct me if this is wrong.
