A programming language is a formal language used to define a computer program. It is a standardized communication technique used to issue commands to a computer. A computer language allows programmers to accurately define the data that a computer needs to use and precisely define the actions that should be taken in different situations. The earliest programming language was created after the invention of the computer, which was used to control the jacquard loom and automatically play the piano. Thousands of different programming languages ​​have been invented in the computer field, and new programming languages ​​are still in place every year. Many programming languages ​​require instructions to describe the program being calculated, while some programming languages ​​are declarative programming, indicating the desired results, rather than how to calculate them. The description of a programming language can generally be divided into grammar and semantics. The grammar is to indicate which symbols or combinations of words are correct in the programming language, and the semantics is the interpretation of programming. Some languages ​​are defined by specification files. For example, the C language specification file is also part of the ISO standard. The post-2011 version is ISO/IEC 9899:2011, while other languages ​​(like Perl) have a major programming language implementation file. , considered as a reference implementation. Programming languages, commonly known as "computer languages", are very diverse and can be divided into three major categories: machine language, assembly language, and high-level language. Every step of the computer's actions, one step, is performed according to a program that has been programmed in a computer language. The program is a collection of instructions to be executed by the computer, and the programs are all written in the language we have mastered. Therefore, people must control the computer to issue commands to the computer through the computer language. There are currently two forms of general-purpose programming languages: assembly language and high-level languages. 1. VB is one of the visual programming tools MSDN launched by Microsoft Corporation. It is the most widely used program development tool in the world. 2. Currently widely used languages ​​are "C++", "Pascal", "Basic" and so on. Among the many computer programming languages, BASIC is the easiest to learn and use. Visual Basic (VB) is available. He is the third-generation BASIC language. It not only inherits the advantages of BASIC language, but also adds graphical interface design tools. It simplifies the complex window programming process and allows the programmer to focus more on the problem solving process. 3, VB is mainly used for the development of some small software and the development of database management system, and the use of some software for secondary development, such as the secondary development of AutoCAD based on Visual Basic, the secondary development of the geographic information system platform. Using Visual Basic to write some macros in the ExcelVBA environment can quickly improve the efficiency and accuracy of office workers processing data. First: VB VB is Visual Basic and is itself a programming language. Visual Basic is a visual, object-oriented, and event-driven, structured, high-level programming language for developing applications in the Windows environment. It's easy to learn, efficient, and powerful enough to compete with the Windows Professional Development Tools SDK. In the Visual Basic environment, using event-driven programming mechanisms, novel and easy-to-use visual design tools, using a wide range of application programming interface (API) functions within Windows, dynamic link libraries (DLLs), object linking and embedding (OLE), Technologies such as Open Data Connectivity (ODBC) can efficiently and quickly develop powerful application systems with rich graphical interfaces in the Windows environment. As the version improves, Visual Basic's features are getting stronger and stronger. After version 5.0, Visual Basic introduced the Chinese version, which has greatly improved its functionality compared to the previous version. Second: VBA VBA, Visual Basic for Applications, is included in Microsoft applications (such as Microsoft Office) and third-party products like WordPerfect Office. It seems a bit contradictory to embed VBA in various applications, but it has the same power as VB. The differences between VBA and VB include the following aspects: 1. VB is designed to create standard applications, while VBA automates existing applications (EXCEL, etc.) 2. VB has its own development environment, and VBA must be parasitic on existing applications. 3. To run an application developed by VB, the user does not have to install VB, because the application developed by VB is an executable file (*.EXE), and the program developed by VBA must depend on its parent application, such as EXCEL. Third: VBScript The full name of VBScript is: Microsoft Visual Basic Script Editon. (Microsoft Corporation Visual BASIC Script Edition). As its literal disclosure, VBS (further abbreviation for VBScript) is a scripting language based on Visual Basic. I further explain that Microsoft Visual Basic is a set of visual programming tools from Microsoft Corporation. The syntax is based on the Basic. scripting language. It is not compiled into binary files. The source code is directly interpreted and executed by the host. Simply put, you The written program does not need to be compiled into .exe, but the source program of .vbs is sent directly to the user, and the user can execute it. VBScript is also the default language for ASP, and can also be used in Windows Scripting (Shell Script) and Web Page Encoding (HTML). Although its syntax is similar to VB, it is a completely different language. VBS does not run using the VB runtime, but is interpreted by the Windows Script Host (wscript.exe - Microsoft Windows Based Script Host). The differences between the two languages ​​affect the performance of ASP sites. Fourth: VB.Net Visual Basic.NET evolved from the Visual Basic language and is a language designed to efficiently generate type-safe and object-oriented applications. Visual Basic allows developers to develop programs for Windows, the Web, and mobile devices. As with all languages ​​for the Microsoft .NET Framework, programs written in Visual Basic have the advantages of security and language interoperability. VB.net is Microsoft's latest platform technology and a language of .netframeworkSDK. There is no difference in functionality between VB.net and VC#.net. The executable file generated after compilation is called Assembly, which is an assembly. The version number of VB.net is VisualBasic7.0, and its operation is based on the CLR (CommonLanguageRuntime) and MSIL (Microsoft Intermediate Language) virtual machines. In fact, its mechanism is similar to Java. The characteristics of VB.NET 1. Really become object-oriented and support inheritance language. 2, the form designer supports visual inheritance, and contains many new features, such as automatic change of form size, resource localization support, data class tools inherently support XML data. 3, directly built on the .NET framework, so developers can make full use of all .NET platform features, but also can interact with other .NET languages. 4. XCOPY deployment for Windows applications, developers no longer need to worry about the version of the DLL. Led Wall Lamp,Outdoor Wall lighting,High Quality Wall Lamp Kindwin Technology (H.K.)
