VB中如何实现连续播方多个声音文件？

如题。我想在VB中实现：单击一下command1，就自动播放1.wav,2.wav,3.wav。 我想用mmcontrol控件来做，请问应该如何操作，谢谢
为什么这样只能播放最后一个文件呢？
MMControl1.FileName =app.path & "1.wav" MMControl1.Command = "Open"
MMControl1.UpdateInterval = 1000
MMControl1.Command = "Play"

MMControl1.FileName =app.path & "2.wav" MMControl1.Command = "Open"
MMControl1.UpdateInterval = 1000
MMControl1.Command = "Play"
MMControl1.FileName =app.path & "3.wav" MMControl1.Command = "Open"
MMControl1.UpdateInterval = 1000
MMControl1.Command = "Play"

能讲具体点么？我不仅是个新手，而且我还是个外行

Dim i As String

Private Sub Command1_Click()
MMControl1.FileName = "C:\WINDOWS\Media\Windows XP 注销音.wav"
MMControl1.Command = "Open"
MMControl1.UpdateInterval = 1000
MMControl1.Command = "Play"
End Sub

Private Sub Form_Load()
i = 0
End Sub

Private Sub MMControl1_Done(NotifyCode As Integer)
i = i + 1
MMControl1.Command = "Close"
Select Case i
Case 1
MMControl1.FileName = "C:\WINDOWS\Media\Windows XP 启动.wav"
MMControl1.Command = "Open"
MMControl1.Command = "Play"
Case 2
MMControl1.FileName = "C:\WINDOWS\Media\Windows XP 关机.wav"
MMControl1.Command = "Open"
MMControl1.Command = "Play"
End Select
End Sub

最简单的方法：用goto实现！或则用Do…while
