hi,
thanks all for your suggestions and time for reply.
but i found a very quick and small methos to play sound file
If My.Resources.welcome.CanRead Then
Dim bStr(My.Resources.welcome2.Length) As Byte
My.Resources.welcome.Read(bStr, 0, My.Resources.welcome.Length)
My.Computer.Audio.Play(bStr, AudioPlayMode.Background)
End If
