Current locale on Windows Phone 8

Question

I am looking for the right way to get the device locale on the Windows Phone 8 under C++/CX.

The following code always returns "en" on Windows Phone 8 emulator.

int ccBuf = GetLocaleInfoEx(LOCALE_NAME_USER_DEFAULT,
                            LOCALE_SISO639LANGNAME,
                            buf, 9);

Answer 1

This function will return the language of the device in two letters format "en", "fr" etc.

#include <windows.h>
std::string platformGetDeviceLanguage()
{
    ULONG numLanguages = 0;
    DWORD cchLanguagesBuffer = 0;
    BOOL hr = GetUserPreferredUILanguages(MUI_LANGUAGE_NAME, &numLanguages, NULL, &cchLanguagesBuffer);

    if (hr) 
    {
        WCHAR* pwszLanguagesBuffer = new WCHAR[cchLanguagesBuffer];
        std::string lang_code = "en";
        hr = GetUserPreferredUILanguages(MUI_LANGUAGE_NAME, &numLanguages, pwszLanguagesBuffer, &cchLanguagesBuffer);
        if (hr) 
        {
            lang_code[0] = pwszLanguagesBuffer[0];
            lang_code[1] = pwszLanguagesBuffer[1];
        }
        delete[] pwszLanguagesBuffer;
        return lang_code;
    }
    return "en";
}
