Sound

How would I get .NET to play a WAV file?

If you have searched the object browser or MSDN you would discover that there are no sound file related classes in the framework, period. For some crazy reason, Microsoft did not anticipate that people might want to play sounds. What you need is the Windows API. There are different API viewers (you can find them with google) or you can just search Google for Windows APIs related to sound. And just a note, as suggested in my sig, this kind of info is generally easily available in either the object browser, MSDN, or Google.

I figured out a pretty simple way to have a .WAV file from your computer play on .NET at a spot in the program.
Insert the following code where you want the sound to play within the program:

My.Computer.Audio.Play("INSERT YOUR FILENAME HERE", AudioPlayMode.Background) be sure to include the quotes around the filename

The "My" feature is only available in VB .NET 2005, hence these features are only available in version 2 of the .Net framework. Keep this in mind.

Play a sound with VB.Net

Hi try this:

Add a new class and name it clsSound.

Paste in the following code overwriting all existing code in the class:

Imports System
Imports System.Runtime.InteropServices
Imports System.Resources
Imports System.IO
Public Class clsSound

Private Shared SND_ASYNC As Integer = 1
Private Shared SND_MEMORY As Integer = 4

Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As Byte(), ByVal hModule As Integer, ByVal dwFlags As Integer) As Integer
Public Shared Sub PlayWavResource(ByVal strWav As String)

Dim strNameSpace As String = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString()


<<CM Get the resource into a stream
Dim resourceStream As Stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(strNameSpace + "." + strWav)
If resourceStream Is Nothing Then
Exit Sub
End If

<<CM Bring the stream into a byte array
Dim wavData As Byte()
ReDim wavData(CInt(resourceStream.Length))
resourceStream.Read(wavData, 0, CInt(resourceStream.Length))

<<CM Play the resource
PlaySound(wavData, 0, SND_ASYNC Or SND_MEMORY)
End Sub
End Class

Next, add the .wav file to the project and in the file properties window set the build action of the file to compiled resource. This is important!

To play the file all you have to do is the following. In this example the code will play the embedded resource file Error.wav

Dim Sound As New clsSound

Sound.PlayWavResource(Error.wav)

post back if you have any problems

The very reason .NET 2.0 is better than 1.1.

I know this is ancient, but I was searching for how to do a simple wav playback myself (DirectSound or whatever it is I think would be sledge hammer for what Im doing)....

So for those of you who prefer C# over VB, you can use System.Media.SoundPlayer for this rather than the My namespace...thanks Lutz!
