#define KEYUP(vk_code)   ((GetAsyncKeyState(vk_code) & 0x8000) ? 0 : 1)
/*
0x8000二进制值是1000000000000000,两者进行与运算
即如果GetAsyncKeyState(vk_code)最高位是1,则取值1,
即此时KEYDOWN   后者正好相反
函数GetAsyncKeyState确定在调用它时某个按键处于弹起还是按下的，以及此按键是否在上一次调用GetAsyncKeyState之后（“又”）按下过（重复也算按下）。
这句话的完整意思是:预定义了一个KEYDOWN参数为vk_code 他的定义的含义是判断一个键是否被按下(GetAsyncKeyState(vk_code) & 0x8000) ? 1 : 0如果按下了就是1,没有按下就是0
然后其它地方用的时候直接用KEYDOWN(vk_code)判断这个键是否按下,相反弹起来是1按下是0
