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：
[hide]//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();
