我自己把程序编好了,发上来给各位参考,请多指教。 代码如下: Dim fn As String
Private Sub Command1_Click() 'CancelError 为 True。 On Error GoTo ErrHandler '设置过滤器。 CommonDialog1.Filter = "All Files (*.*)" '指定缺省过滤器。 CommonDialog1.FilterIndex = 2
'显示“打开”对话框。 CommonDialog1.ShowOpen '调用打开文件的过程。 fn = CommonDialog1.FileName Label2.Caption = fn Exit Sub ErrHandler: '用户按“取消”按钮。 Exit Sub End Sub
Private Sub Command2_Click() MMControl1.Command = "close" End Sub
Private Sub Timer1_Timer() tsy = Text2.Text keep = Text1.Text Static a As Integer, b As Integer a = a + 1 If a = 60 Then b = b + 1 a = 0 If b = keep Then MMControl1.FileName = fn MMControl1.Command = "open" MMControl1.Command = "play" MsgBox tsy, vbOKOnly, "提示" b = 0 End If End If
End Sub 窗体界面倒是可以根据自己喜好设定。
