c ++ GetKeyState（）一些键代码不起作用

Question

您好我正在Windows7上用c ++创建一个游戏并遇到了一个奇怪的问题：

我使用GetKeyState来检索关键状态，到现在为止一直运行良好。

我已经映射了几个键:( INPUTKEY是整数）

   const static INPUTKEY KEY_W = 87;
   const static INPUTKEY KEY_S = 83;
   const static INPUTKEY KEY_A = 65;
   const static INPUTKEY KEY_D = 68;
   const static INPUTKEY KEY_I = 73; // this one is not working
   const static INPUTKEY KEY_V = 86;

我无法获得Key＆＃34;我＆＃34;工作它只是返回它没有被按下0X0000

这是我的获取功能：

    inline static bool isKeyPressed(int keyCode){
        return (GetKeyState(keyCode) & 0x8000);
    }

有谁知道原因可能是什么。在我的窗口MESSAGES循环中，我与Key I没有任何关系......

这是窗口循环：

void Window::run() {
    MSG msg;
    displayState = 1;
    while(PeekMessage(&msg, 0, 0, 0, PM_REMOVE)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

}

LRESULT CALLBACK Window::WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) {
     Window* window = ((Window*) GetWindowLongPtr(hWnd, GWLP_USERDATA));

     switch(message) {
           case WM_PAINT:
           DefWindowProc(hWnd, message, wParam, lParam);
           break;
     case WM_CLOSE:
          window->isCloseRequestedBool = true;
          break;
     case WM_LBUTTONDOWN:
          window->getMousePressState()->leftMouse = true;
          DefWindowProc(hWnd, message, wParam, lParam);
          break;
     case WM_LBUTTONUP:
           window->getMousePressState()->leftMouse = false;
           DefWindowProc(hWnd, message, wParam, lParam);
           break;
     case WM_RBUTTONDOWN:
           window->getMousePressState()->rightMouse = true;
           DefWindowProc(hWnd, message, wParam, lParam);
           break;
     case WM_RBUTTONUP:
           window->getMousePressState()->rightMouse = false;
           DefWindowProc(hWnd, message, wParam, lParam);
           break;
     case WM_MBUTTONDOWN:
           window->getMousePressState()->middleMouse = true;
           DefWindowProc(hWnd, message, wParam, lParam);
           break;
     case WM_MBUTTONUP:
           window->getMousePressState()->middleMouse = false;
           DefWindowProc(hWnd, message, wParam, lParam);
           break;
     case WM_DESTROY:
          window->Destroy();
          PostQuitMessage(0);
          window->displayState = 0;
          return 0;
      default:
          return DefWindowProc(hWnd, message, wParam, lParam);
}
return 0;
