主题：求教，有关调用第三方控件事件

Public axFR601 As new AxFR60Lib.AxFR60()
Public Sub Init()
       AddHandler axFR601.OnPhoneRing , AddressOf OnPhoneRing '指定终端设备连接的线路有振铃产生
End Sub

Public Sub OnPhoneRing(ByVal sender As System.Object, ByVal e As AxFR60Lib._DFR60Events_OnPhoneRingEvent)
        Dim str As String = "振铃 "
       messagebox.show(str)
End Sub

AfterOpenProject

AfterLoad

axFR601.BeginInit()
e.Form.BaseForm.Controls.add(axFr601)
axFR601.EndInit()

以上调用事件方法是否正确？请指教！多谢了！
