GetAsyncKeyState 的可能参数/组合 - C++

Question

我一直在尝试找出函数 GetAsyncKeyState()

的总参数列表

我检查了MSDN 和许多其他 Google 搜索结果页面，但找不到明确的答案。

例如

char t = 58; (Would be number 4)
char y = 8;  (Would be BACKSPACE key)

我知道这些的原因是我可以使用循环来查询带有每个可能参数的函数。

for(i = 0; i <= 500; i++) 
{
      if(GetAsyncKeyState(i) == -32767)
      {
           cout << "key pressed : ";
           cout << i << endl;
      }

 }    

我宁愿知道可能的参数，而不是像在循环检查高达 500 时那样在黑暗中随机拍摄。

Answer 1

这里有一个所有键的列表：VirtualKeycodes github repo

我已经使用这些键制作了一个概念验证记录器，我将它们转换为 std::map 格式并将它们放入 std::array 中。

我遍历它们并记录所有按下的键，它包括 336 个虚拟键，应该是它们的全部。

输出如下：

#include <Windows.h>
#include <iostream>
#include <utility>
#include <array>

std::array<std::pair<char*, BYTE>, 336> vkeys
