等待按键ESC,否则一直sleep(处于暂停状态)GetAsyncKeyState的参数指出要检查键的虚键代码。结果的高位指出该键当前是否被按下(是为1,否为0),因此必须用位操作判断。
这条语句什么意思while(!(GetAsyncKeyState(VK_ESCAPE) & 0x8000)) Sleep(20);等待按键ESC,否则一直sleep(处于暂停状态)GetAsyncKeyState的参数指出要检查键的虚键代码。结果的高位指出该键当前是否被按下(是为1
比如下的码是 VK_DOWN ,ESC是 VK_ESCAPE GetAsyncKeyState 取异步键状态。 比如,一般情况下,你可以在操作系统的控制面板中设置鼠标左右键的映射(实际的鼠标左键可以映射成右键点击事件),或者通过程序也可以这样设置,这样就产生了物理键状态(实际的),逻辑键状态(虚拟的,)。使用 GetKeyState,GetKeyboardState,等函数...

short a = ::GetAsyncKeyState(VK_LSHIFT) printf( "0x%x",a); sleep(10); } } 当然,用MessageBox可以这样写: if(short a = ::GetAsyncKeyState(VK_LSHIFT)) { char buffer[30]; sprintf(buffer, "0x%x",a); MessageBox(0, buffer, "a的值", MB_OK); ...

MSDN上给出了样例非常恰当For example, the call GetAsyncKeyState(VK_LBUTTON) always returns the state of the left physical mouse button, regardless of whether it is mapped to the left or right logical mouse button.也就是说假设你又一次设置了映射,GetAsyncKeyState还是仅仅读取物理状态。
