Media player problems...

Anyone mind telling me what's wrong in this code?

VB Code:

REM Play a sound
    Public Function PlaySound(ByVal Filename As String, Optional ByVal optPlayCount As Integer = 1, Optional ByVal optVolume As Integer = 100) As Boolean
        Dim x As New AxWMPLib.AxWindowsMediaPlayer
        Try
            x.URL = Filename
            x.settings.playCount = optPlayCount
            x.settings.volume = optVolume
            x.Ctlcontrols.play()
        Catch ex As Exception
            'An error occured
            Return False
            Exit Function
        End Try
 
        'Sound played successfully
        Return True
    End Function

If you're just playing a short WAV sound then you're better off using the PlaySound API function. If you want to use WMP without an interface, i.e. without adding the control to your form, then I'd suggest not using the ActiveX control but rather an instance of the WMPLib.WindowsMediaPlayer class, which is intended to be used that way. More than that I can't really say as I don't have much experience in that regard.

Hi Ruku,

I think you forgot to declare some functions.
That is how I play a sound with Playsound, try it:

VB Code:

Const SND_ASYNC As Integer = &H1
    Const SND_FILENAME As Integer = &H20000
    Const SND_NODEFAULT As Integer = &H2
    Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Integer, ByVal dwFlags As Integer) As Integer
 
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        PlaySound("c:\1.mp3"), 0, SND_NODEFAULT Or SND_ASYNC Or SND_FILENAME)
    End Sub

Hope it helps,

Not...

I just wanted to use integrated .net functions instead, but I guess I'll resolve to API...

bah well, thx guys...

The WMP control is COM anyway so it's not really .NET anway. Note that .NET 2.0 has a SoundPlayer component. Also, you may like to follow the Mentalis.org link in my signature. They have two classes that wrap certan API functions to make playing WAV and other sound files easier. When you get right down to it, that's all the .NET SoundPlayer will do anyway.

Meh, I guess I'll just resolve to API anyhow... :p
