Windows CE下的键盘钩子

在coredll.dll中有SetWindowsHookEX相关函数，这里用LoadLibrary和GetProcAddress可以调用。 以下是测试代码： //Install the KB hook by passing the //handle of the application to be hooked //and the address of the KB procedure //which will handle all the KB events if(!ActivateKBHook(hInstance, LLKeyboardHookCallbackFunction)) { MessageBox(GetActiveWindow(), TEXT("Couldn't intall hook...Terminating"), TEXT("Warning"), NULL); exit(1); }

//LLKeyboardHookCallbackFunction is the funtion whose //address we passed to the system while installing the hook. //so all the KB events will bring the control to this procedure. //Here we want that when the user presse left or //right key it should be interpreted as an UP key //so now you can allow the user to configure the //key boards the way he/she wants it LRESULT CALLBACK LLKeyboardHookCallbackFunction( int nCode, WPARAM wParam, LPARAM lParam) { if(((((KBDLLHOOKSTRUCT)lParam)->vkCode) == VK_LEFT) || ((((KBDLLHOOKSTRUCT)lParam)->vkCode) == VK_RIGHT)) { //Generate the keyboard press event of the mapped key keybd_event(VK_UP, 0, 0, 0);

    //release the mapped key
    keybd_event(VK_UP, 0, KEYEVENTF_KEYUP, 0);
}

//let default processing take place
return CallNextHookEx(g_hInstalledLLKBDhook, nCode,
                                          wParam, lParam);

}

//we are done with the hook. now uninstall it. DeactivateKBHook(); Windows CE下的键盘钩子程序的应用这里有个例程...
