	//实现了IDispatch，把它传给COM组件后，COM组件就可以调用它的Invoke()函数(如在FireShow()中)，
	//COleDispatchImpl::Invoke()中用到了dispatch map，这个表由DECLARE_DISPATCHMAP声明，
	//在BEGIN_DISPATCHMAP(,)、END_DISPATCHMAP()中被填充，比如Show()、Show2()。这样Invoke()
	//就可以根据dispid在dispatch map中找到这两个函数，从而调用它们，从而实现了连接点。
	//另一方面，也可以看到用dispinterface声明的事件接口本身并不是从哪个接口继承的，既不是IUnknown
	//也不是IDispatch,只不过通过一系列手段，使Invoke()能识别其中的属性、方法而已。
	//dispinterface表示这个接口是纯IDispatch接口。
