1 虚拟按键Virtual-Key的应用场景

在开发Win32程序时当需要程序接受键盘按键消息时,通常需要WM_KEYDOWN消息的wParam参数判断到底是按下了键盘的哪一个键,
示例代码可参考:

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    HDC hdc;
    PAINTSTRUCT ps;

    switch (message)
    {
    case WM_KEYDOWN:
    {
        // W键
        if (wParam == 0x57)
        {
        }
        // A键
        else if (wParam == 0x41)
        {
        }
        // S键
        else if (wParam == 0x53)
        {
        }
        // D键
        else if (wParam = 0x44)
        {
        }

        break;
    }


    default:
        return DefWindowProc(hWnd, message, wParam, lParam);
    }
    return 0;
}

这里WM_KEYDOWN消息的wParam参数代表着键盘上按键的虚拟按键值Virtual-Key Codes,通过虚拟按键值我们可以确定键盘上是哪一个键被按下,并且做出相应的逻辑。
