Hi all
Anybody give me some details how to change the value of Non-Unicode Language
setting programatically.
Thanks

But first please elaborate. What is your problem?
 

Ok.
In one of my program, i am creating some labels and menus at run-time. I
have to assign Arabic text to the labels captions and menus.
As it should be, when the value for the "Language and Non-Unicode" set to
other than Arabic, I am getting all ???? mark symbols for the labels and
menus.
So i want to check atleast when the program runs for the first time, detect
the value for "Language and Non-Unicode" and set to Arabic, if not set.
If it is possible through program. Is it must to restart the pc?.
I will be happy, is there anyway to give the sepecific language value only
for the my program.
Thanks
SA

Hi Bob Gonder
I have Non-Unicode Language set to English (United States).
If i run the program i'll see ????.
I placed the code in the WinMain() function
int iLang = 0;
iLang = MAKELCID(MAKELANGID(LANG_ARABIC,
SUBLANG_ARABIC_KUWAIT),SORT_DEFAULT);
SetThreadLocale(iLang); //returns true
But still the captions are not changing.
Thanks

I don't think that there is natural way of changing
"Language for non-Unicode programs" by code.
That operation typically is followed by two dialogs
(CP>Regional and Language Options>Advanced)
to choose loading from HD or from CD and
confirmation to restart PC.
Afterall I saw cluster of REG entries specially
designed to patch existing entries, which is completely
wrong aproach in my oppinon.
What you can test, in addition to SetThreadLocale()
is to make few helper functions to change CodePage
of concrete objects.
The example shown is for use with resource files, and
you should be interested in CodepageToCharset().
(I copied this from one old thread here)
// MyStrings.rh
#define IDS_CANCEL 27114
// Strings.rc
#pragma code_page(1252)
#include "MyStrings.rh"
STRINGTABLE
LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US
BEGIN
IDS_CANCEL, "Cancel"
END
STRINGTABLE
LANGUAGE LANG_CZECH, SUBLANG_DEFAULT
BEGIN
IDS_CANCEL, "Zrusit"
END
Then, in your application, create a couple of helper functions to assist you
when setting the language:
static const TFontCharset CodepageToCharset( unsigned int cp )
{
CHARSETINFO csi;
if ( (cp == 0) || (!TranslateCharsetInfo( (unsigned long *)cp, &csi,
TCI_SRCCODEPAGE )) )
{
return OEM_CHARSET;
}
return (TFontCharset)csi.ciCharset;
}
static AnsiString InternalLoadStr( int ErrorCode )
{
const int MaxResourceBufferSize = 4096; // maximum resource string length
is 4095 bytes
char string[MaxResourceBufferSize];
LoadString( GetModuleHandle(0), ErrorCode, string,
MaxResourceBufferSize );
return AnsiString( string );
}
Finally, set the thread locale to the desired language:
SetThreadLocale( 0x0409 ); // U.S. English
btnCancel->Font->Charset = CodepageToCharset( 1252 ); // western codepage
btnCancel->Caption = InternalLoadStr( IDS_CANCEL );
SetThreadLocale( 0x0405 ); // Czech locale
btnCancel->Font->Charset = CodepageToCharset( 1250 ); // eastern europe
codepage
btnCancel->Caption = InternalLoadStr( IDS_CANCEL );
