to customize attributes in components? Do I need to bind data? How do I draw the component appearance? How to communicate with IIS? Do I need post-back? Many and many problems require component designers to consider them one by one. Therefore, if you care about it, isn't it just designing a component? How difficult is this! So, I will smile, because I know, you must be joking. But do not be afraid, "programmers need to explore the spirit !" ASP. NET Component

Analysis of callback ideas in android system design, android callbackI. Why do I write this article? During the process of gradually getting into touch with android development, I have found that many callback ideas are used in android (at least in app development. For example, the lifecycle of an activity and fragment are implemented by callback functions. One of the event processing mechanisms in android

).Dimitri rule (least known principle)It means that a class knows more about a class that it depends on than it burns better. This means that no matter how complex a dependent class is, the logic should be encapsulated inside the method and provided externally through the public method. This way, the class can be minimized when the dependent class changes.The least known principle is another way of saying it: communicate only with direct friends. As long as there is a coupling relationship betwe

In fact, in the domain analysis stage, the attributes of an object are not important. What is important is to identify the operations of an object. Step 6 of OOA D is to draw an implementation class diagram. The above steps are the
