NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Resources. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The My.Computer.Audio.Play method plays the specified sound in the background when AudioPlayMode.Background is specified.


Sub PlayBackgroundSoundFile()
    My.Computer.Audio.Play("C:\Waterfall.wav", 
        AudioPlayMode.WaitToComplete)
End Sub


This code can run only within a Windows Forms application.

The file name should reference a .wav sound file on your system.

To simplify the management of your sound files, consider storing the files as application resources. The files can then be accessed through the My.Resources object.
