//判断当前系统语言，如果是中文，则切换为英语，如果时英语，则切换为中文
if (GetLanguage ()==0x0409)
{
    
    
SetLanguage(0x0804);
SetTagChar("@Language","C");
}
else
{
    
    
SetLanguage(0x0409);
SetTagChar("@Language","E");

Script extension

GetLanguage ()

Usage of the Getlanguage function in the script: It is mainly used to establish the language of the current running system.
Read out the instance of the current running system language

{
    
    DWORD rt_language;
rt_language = GetLanguage ();//获得当前语言
//自定义代码
//在那里用户可以使用返回值做某事```
}

1). Read the current operating system language and buffer it in rt_language.
2). Execute custom code that handles the return value.

SetLanguage(DWORD dwLocaleI)

Change the language setting in the runtime system

{
    
    
SetLanguage(0x0407);//德语
}

The operating language of the system is set to German
PS: the formal parameter in the function is the system language ID, and the system language ID table is as follows
