We all manipulate instances of a reference type by reference to the instance.So, there are three types of variables: Instances of value types Instances of reference types Reference But here's a very interesting question. As we all know, the spatial allocation of instances of reference types is on the heap. But how does the space for a in the example above be allocated? It

For CORBA objects, the following two life cycle events are important: • The life cycle of creating--corba objects begins with the creation of events. CORBA objects are typically created from factory objects, that is, objects provide operations to create new objects. Recall that, at the IDL level, CORBA does not have a

{ } As you can see, the page class is a HttpHandler. The whole process is that when a client sends a resource request to the server, the request first arrives at the http.sys of IIS. The HTTP.sys then sends the application Pool of the request path accordingly. The application pool then sends the request into the worker Process (W3WP.exe) to load the ISAPI Extension. ISAPI creates a HttpRuntime object to process requests through HttpModule and HttpHandler. Then the page
