Windows消息 [英] Windows Messages

问题描述

您好，当我的表单没有焦点时，是否可以获取Windows消息?

感谢您的答复，但我有一个问题:
我有Windows窗体应用程序而不是控制台应用程序，并且我修改了代码以过滤消息:

Hello, is it possible to get windows messages when my form doesn''t have focus?

thank you for the reply, but I have a problem:
I have a Windows Forms Application not a Console Application and I modified the code to filter the messages:

protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
            if (m.Msg == 0x0319)
            {
                MessageBox.Show("");
            }
        }

现在，每当我在Windows Media Center的遥控器上按一个按钮(如播放，暂停)时，我都应该看到一个MessageBox.当表单具有焦点时，代码可以正常工作，但是当我单击另一个应用程序(例如，浏览器)时，再也看不到MessageBox了.

P.S.我的应用程序的目标是使遥控器可以与所有音乐/视频播放器一起使用.

Now each time I press a button(like play, pause) on my Windows Media Center''s remote control I should see a MessageBox. The code works fine when my form has focus but when I click another application(for example my browser) I don''t see any more that MessageBox.

P.S. My application''s goal is to make the remote control work with all the music/video players.

推荐答案

是.

protected override void WndProc(ref Message m)
            {
            base.WndProc(ref m);
            Console.WriteLine(m.ToString());
            }

警告:请勿运行此程序并期望良好的响应时间.您会收到很多Windows消息，因此响应速度会很慢，因为控制台输出会像疯子一样滚动！

WARNING: Don''t run this and expect good response times. You will get a lot of windows messages, and thus slow response because the console output will be scrolling like a loony!

看起来就像您正在构建间谍应用程序.

Looks like you are building a spy application.
