Vb. NET in the process summary



vb.net with the object-oriented characteristics, in use, some of the object information is expressed using attributes or functions, and sometimes the overall understanding of the software and use of the relevant, so summarized under vb.net Some of the foundation, through the room charge system to deepen understanding.

    in, the overall process is divided into two broad categories: the system process and the customization process. The process of the system is divided into functions and events within the system, some common internal functions,SystemSome functions of the prefix belong to this part. The other is the custom process, and the custom process is divided into5Big class, the most common isSubprocess, we were just getting started with theSubThe code in there , and later.Functionprocess, both of which are included in the method. Plus the following Propertyprocess,Eventprocess, which is the three main features of object-oriented objects: Properties, events, methods. Also proves thevb.netis a fully object-oriented, high-level language.         method sub and function , you can use parameters or with 0 parameters; but sub process is a set of code organized by a user-defined format, with no return value, function The process must have a return value.

attributes are used to describe the state and characteristics of an object, and the values of data members in a class are generally used to represent the state and characteristics of an object, to flexibly use the values of data members and to secure data, to associate attributes with data members, and to define properties as public, the outside world can manipulate the property and indirectly manipulate the data members of the class, and improve the data security.

an event is a whole, consisting of the definition of an event, the triggering of an event, the definition of an event object, and the event handler function. A popular understanding event is an action, and the process and result of the action. In vb.net , the start of an event triggers the event's process and then passes the user-defined event procedure to get the expected result. The operator procedure is similar to the operator overloading in C + + and is also a user-defined event procedure based on the original operator.

in the use of each process to pay attention to their own scope, to clarify the role of each process, and then rational use of scope, a better understanding of this part of the content.
