_IRDPSessionEvents 接口 (rdpencomapi.h)
实现此接口，以在事件发生时接收通知。
继承
_IRDPSessionEvents 接口继承自 IDispatch 接口。
注解
RDPViewer COM 对象是可连接的对象。 若要从 对象接收有关连接共享会话的事件，应用程序可以实现 _IRdpSessionEvents 并执行以下步骤。
- 在 RDPViewer 上调用 IUnknown：：QueryInterface 以获取指向 IConnectionPointContainer 接口的指针。
- 调用 IConnectionPointContainer：：FindConnectionPoint（指定
__uuidof(_IRdpSessionEvents)为 riid 参数）以获取指向客户端控件事件的 IConnectionPoint 接口的指针。 - 调用 IConnectionPoint：：建议 指定要在其中调度事件的 _IRdpSessionEvents 调用应用程序自己的实现。
实现 IDispatch：：Invoke 时，应用程序可以使用以下 DISPID。
