Dim Flname As String

End Sub

Private Sub mnunormal_Click()

End Sub

Private Sub mnuautst_click()

End Sub

Private Sub mnustart_Click()
If mnustart.Checked = True Then
mnustart.Checked = False
MediaPlayer1.autoStart = False
Else
mnuautst.Checked = True
MediaPlayer1.autoStart = True
End If
End Sub

Private Sub Timer1_Timer()
ss = ss + 1
If ss >= 60 Then
mm = mm + 1
ss = 0
If mm >= 60 Then
hh = hh + 1
mm = 0
End If
End If
Label1.Caption = Format$(hh, "00") & ":" & Format$(mm, "00") & ":" & Format$(ss, "00")


End Sub

[解决办法]
MediaPlayer1.FileName = Flname
把这句改成MediaPlayer1.url=Flname 就可以了
