V:When a constructor is called, one of its first tasks is to initialize its v p t r. Therefore, it can only know that it is a "current" class, and ignore whether there is a successor behind this object. When the compiler generates code for this constructor, it generates code for the constructor of this class-neither the base class nor, it is not a derived class for it (because the class does not know who inherits it ).Therefore, the V p t r used must be for the V

software architecture is also improved.I wonder if my answer is satisfactory to you. Remember to give it a high praise.Meanings of Dao, service, and action
The main function of an action is to organize the service. For example, if you want to perform permission verification, the request will be obtained by the action. How can you verify it? No matter what the user wants to do with the service. After obtaining the result returned by the Service, determine the Next Hop Based on the result (if the

that case, is it necessary to set up a button to cross the road?
The buttons, which are not actually functional, are called "placebo buttons", and they are actually everywhere: crosswalk, subway stations, and automatic temperature regulators. They don't have the actual functionality, they just give the user a sense that I can do it manually even in the automatic operating system.
Sounds strange, why to give the user this feeling? Why deceive users? Because users always want to have the feelin

One of the most common problems that first-time developers run into is the blue screen stop 0x0000007b error. although the book Windows XP embedded advanced has the solution listed in the tips-and-tricks chapter, the explanation is not as detailed as it cocould be, and developers still run into the problem.
The error is occurring because a driver is missing from the image such as a PCI bus driver, disk driver, or IDE controller driver. many developers start the xp
