Sets the locale for the annotation library.


#include "l_bitmap.h"

L_LTANN_API L_TCHAR * L_AnnSetlocale(nCategory, lpszLocale)


L_INT nCategory

Category affected by locale.

const L_TCHAR * lpszLocale

Locale name. Pass NULL to return the current locale.


Value Meaning
!NULL A pointer to the string representing the specified locale and category
NULL Indicates that the category or locale parameter value was invalid


This function is used under rare circumstances. It is necessary only when running non-unicode applications that must display text that is not part of the ASCII character set (for example, Japanese characters). Non-ASCII text (i.e. a Japanese or Arabic character) can be stored non-ambiguously in unicode. However, for non-unicode applications, the multi-byte representation of such characters depends on the code page. In this case, you must set the code page appropriately. For example, a non-unicode annotation application can display Japanese characters only if the code page is set to a Japanese code page (like Japanese_Japan.932).

Pass NULL for the parameter pszLocale to get the current locale, leaving the current locale unchanged.

Note that in the MAIN C API annotation demo, you can change the locale using L_AnnSetlocale. Internally, this function calls Microsoft C API setlocale. For details, see the MSDN documentation.

Required DLLs and Libraries

This example shows how to set the locale of the annotation library.

#include <locale.h> 
L_TCHAR* DisplayCurrentLocale() 
   L_TCHAR  szMsg[200]; 
   // Display the current locale 
   L_TCHAR* pszMsg = L_AnnSetlocale(LC_ALL, NULL); 
   if (pszMsg != NULL) 
      wsprintf(szMsg, _T("Current Locale: %s"), pszMsg); 
      _tprintf(_T("%s"), szMsg); 
   return pszMsg; 
L_INT AnnSetlocaleExample() 
   L_TCHAR* pszOriginalLocale = DisplayCurrentLocale(); 
   // Set the locale for English/United states 
   L_AnnSetlocale(LC_ALL, TEXT("English")); 
   // Set the locale for Japanese 
   L_AnnSetlocale(LC_ALL, TEXT("Japanese")); 
   // Set the locale for Arabic 
   L_AnnSetlocale(LC_ALL, TEXT("Arabic")); 
   // Set to the original locale 
   L_AnnSetlocale(LC_ALL, pszOriginalLocale); 
   return SUCCESS;
