在Windows服务中播放默认Windows声音 [英] play default Windows sounds in Windows Service

问题描述

我在VS2010的VB.net中开发Windows服务



在某些情况下，我想播放用户通知的系统默认声音。



我曾尝试使用代码播放声音，但它没有播放任何声音。

I am developing windows service in VB.net in VS2010

In some case I want to play system default sound for user notification.

I had tried following code to play sound but it''s not playing any sound.

System.Media.SystemSounds.Question.Play()

 'I checked by attaching debug that the path is correct
My.Computer.Audio.Play(Path.Combine(My.Application.Info.DirectoryPath, "Blip.wav"), AudioPlayMode.Background)

My.Computer.Audio.PlaySystemSound(Media.SystemSounds.Question)

即使我使用InstallUtil安装服务后检查服务属性中的允许与桌面交互复选框



我检查了与我的电脑连接的扬声器。



我在win xp中测试了它并赢了7



请帮我解决这个问题并让我知道我哪里错了。



谢谢

Even I checked the check box of "Allow to interact with desktop" in service properties after installing service using "InstallUtil"

I checked the speaker connected with my pc.

I have tested it in win xp and win 7

Please help me to resolved this issue and let me know where I am going wrong.

Thanks

推荐答案

我认为你不能从服务中播放声音。至少，我从来没有听说过有声播放过的单一服务。这总是留给用户模式的应用程序，该应用程序与服务对话并通过命名管道或其他一些通信方法接收来自它的通知。

I don''t think you can play sounds from a service. At least, I''ve never heard of a single service ever playing a sound. That was always left up to a user-mode application that talks to the service and receives notifications from it, via named pipes or some other communication method.
