to publish an interface for accepting new data types ." I answered it all at once.
"It seems that you have mastered the basic steps of interface operations ." I am so happy with the comments from Da li. "I would like to sum up that the main reasons for using interface inheritance instead of class inheritance are: when the application requires a lot of irrelevant object types to provide some function, the interface is more adaptable. The interface is more flexible than the base class, because y

I. How to define and trigger events
There are two syntaxes for defining events. One is to explicitly specify the delegate type of the event processing method:
[Modifier] EventEventnameAsHandlertype
The other is to write the event processing method parameters directly in the Definition Statement, which is a method that implicitly specifies the delegate type:
[Modifier] EventEventname(ARGs)
In this definition, VB generates a n

With Microsoft. the launch of the NET development platform has undoubtedly brought great news to countless VB developers, including no inheritance, ugly error capturing, no object pool, and no underlying development, it is followed by a complete OO-oriented feature, a wide range of class libraries that support XML. When someone prefers C #, C ++ developers are dismissive about it, but what is more important

terms rather than the member names when they are specifically encoded. I like to use the term "structors" to refer to constructs and destructors. In the VB6 language, the specific "structors" is Class_Initialize and Class_Terminate. Under VB.net, the Class_Initialize method is renamed to New, and Class_Terminate is finalize.
The programmer is not allowed to add parameters to the Class builder according to the VB6 implementation restrictions. However, VB

After the VB6 upgrade to. NET, some people are not clear about the sound processing, such as when the program is wrong, customizing a sound playback, or the program's background music, including game music, and so on. Here are some simple and achievable solutions in vb.net:

Multithreading VB. NET (Visual Basic.NET) is to accommodate Microsoft. NET Framework, the development tools for Visual Basic have been significantly modified. It is more powerful and easier to use than the Visual Basic 6.0 feature. One of the most important changes is object inheritance, in which all manageable types are derived from System.Object vb.net.

Database design is the process of designing database structure according to user's requirement, specifically, the database design is for a given application environment, under the guidance of the theory of the CuO database, constructs the optimal database pattern, establishes the database and its application system on the database management system, enables it to store the data effectively, The process of meeting the various needs of the user. In the end of the database how to design, through th
A constant is a constant in the process of running the program. Since some constants are often used repeatedly during programming and development, and their meanings are sometimes difficult to remember, we need to check each time. If constants are defined, they will simplify them, this improves code readability and maintainability.Note: you cannot arbitrarily modify or assign new values.
VB. there are two types of constants in.
The ability to operate arrays is important in any programming language. Similar to other languages, VB. NET provides a simple way to group data and store them in an array structure. In this article, we will review the Declaration and use of arrays.

Arrays are usually used to store values and objects of similar types. It allows grouping of variables and indexing. An array has an upper and
