请问如何让应用程序能接收到perform,sendmessage or postmessage函数发出的消息?如 wm_keydown消息如何确定那个键被按下。
去看一下,北大版 <windows程序设计>(第五版) Charles Petzold的经典之作 windows程序员的必备之书。或者参考msdn: WM_KEYDOWN The WM_KEYDOWN message is posted to the window with the keyboard focus when a nonsystem key is pressed. A nonsystem key is a key that is pressed when the alt key is not pressed. WM_KEYDOWN // 按下:nVirtKey nVirtKey = (int) wParam; // virtual-key code lKeyData = lParam; // key data
