Dear all,

Anybody know how to detect the sound device is existed or not?

In my application, i need to play music, if sound device got problem or do not installed, i need to prompt a message box and change the play button to grayout.

any clue?

Hi,

I'm afraid this is for VB.NET hope u could convert it to C# without a problem.

But it should work.

Private Declare Function waveOutGetNumDevs Lib "winmm.dll" () As Long
Private Sub cmdCanPlay_Click()
Dim i As Long
i = waveOutGetNumDevs()
If i > 0 Then
MsgBox "Your system can play sound files.", _
vbInformation, "Sound Card Test"
Else
MsgBox "Your system can not play sound Files.", _
vbInformation, "Sound Card Test"
End If
End Sub

Regards,

Geethanga.
