[RESOLVED] Using Direct Sound

[Brian M.]

Hello. I am trying to use direct sound to play a wav file, so I may animate a picture box while the wav file is playing. I have made a device object and a secondary buffer object and when I run the program I get an error message(see attached image), but after I click continue, the wav file plays and it plays every time I click the play wav button. I am using a test project to work out the bugs before I implement the direct sound in my other project. Below is the the code I am using. Can someone tell me what I am doing wrong? I would greatly appreciate it. The code needs a form named form1, and a button named xPlayButton.

Imports Microsoft.DirectX.DirectSound

Public Class Form1

    Private Sub xPlayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xPlayButton.Click

        Dim sDevice As New Device
        sDevice.SetCooperativeLevel(Me, CooperativeLevel.Normal)
        Dim secBuffer As New SecondaryBuffer(My.Resources.b, My.Resources.b.Length, sDevice)

        secBuffer.Play(0, BufferPlayFlags.Default)

    End Sub

End Class

Well I figured out the reason my code was throwing an error. I didn't link to the Microsoft.DirectX library. I added this line:"Imports Microsoft.DirectX" and now it runs fine. I found that using the direct sound isn't really that hard. Dim a device object, dim a secondary buffer object, set the device cooperation level to the form that is calling direct sound, load the sound into the secondary buffer and viola' you are using direct sound. Easy as pie.
