I used to use the UpdatePanel updateprogress and other controls, and even to the extent of abuse, just blindly pursuit of no refresh, while the loading picture hints, this looks more beautiful, but feel more loss of performance, and sometimes also damaged the integrity of the site. But after learning Jquery, I learned about Jquery.ajax, jquery.get, and so on, so that we could use WebService and. ashx files to interact with the server.

Use of C ++ Nested classesThe nested class of C ++ refers to the class defined in the class. It is similar to the members of the peripheral class and is also modified by the corresponding access permission modifier.1. The nested class can directly carry static member variables in the peripheral class.2. Nested classes can access members of peripheral classes by referencing, pointer, or object, regardless of whether the Members are public, private, or protected.3 when a nested class is modified b
