windows客户端开发--为国际化做准备

一款好的windows client，当然要做国际化。

今天先介绍几个函数，获取windows操作系统的使用语言。

GetSystemDefaultLCID函数
这个函数很简单，没有参数，只有返回值：
Returns the locale identifier for the system locale

GetSystemDefaultUILanguage

    Retrieves the language identifier for the system default UI language of the operating system, also known as the "install language" on Windows Vista and later. For more information, see User Interface Language Management.

GetUserDefaultUILanguage
Returns the language identifier for the user UI language for the current user. If the current user has not set a language, GetUserDefaultUILanguage returns the preferred language set for the system. If there is no preferred language set for the system, then the system default UI language (also known as “install language”) is returned. For more information about the user UI language, see User Interface Language Management.
原型：

    LANGID GetUserDefaultUILanguage(void);

    #include<iostream>
    #include<Windows.h>
    #pragma comment(lib, "Kernel32.lib")
    int main()
    {
    auto iter = GetUserDefaultUILanguage();
    auto iter2 = GetSystemDefaultUILanguage();
    std::cout << iter << std::endl;
    std::cout << iter2 << std::endl;
    return 0;
    }
    //输出：
    //2052
    //2052
