If I understand what you are trying to do, then something like this should work.

 

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick  
        Label1.Text = TimeOfDay
        bellEnabled = True

        For Each r As DataGridViewRow In DataGridView1.Rows
            Dim jam As String = Convert.ToString(r.Cells)

            If r.Cells("jm").Value = Label2.Text And bellEnabled = True Then 'taken from datagridview
               PlayBell()
            End If
        Next
End Sub
Sub New()
       Dim nmFile As String
       nmFile = "E:\bell1.mp3"
       waveOutDevice = New WaveOut(callbackInfo)
       mainOutputStream = CreateInputStream(nmFile)
       waveOutDevice.Init(mainOutputStream)
End Sub
Private Sub PlayBell()
       If waveOutDevice.PlaybackState <> Playing Then
            waveOutDevice.Play()
       End If
End Sub

Sorry, I new in vb.net. I've added 'InitializeComponent()' since the code gives me warning "should call InitializeComponent method." But I still can't get it worked well. In the database I put 3 data (08:00:00, 08:20:00, and 08:40:00). The sound play well when the timer match the 1st data (08:00:00), but not for the next two data. There's no sound at all
