The question of VB language, what language is VB language?

Functions, variable names, procedure names, etc., are not case-sensitive.

Only constants are case-sensitive.

For example: end if

end if

end if

All three of these can be written.

But binalian="aa"

and binalian="aa"

It's not the same private sub text1 mousemove(button as integer, shift as integer, x as single, y as single).

if <>"" then

true true

falseelse = false

falsetrueend if

end sub

private sub cmdclose_click()end end sub

This will allow you to private sub cmdclose click()end end sub

private sub text1_mousemove(button as integer, shift as integer, x as single, y as single)

if <>"" then

true true

falseelse = false

falsetrueend if

end sub

It's okay to do this, it doesn't matter the order of a process, either in front or after.

Of course, it is case-sensitive, but the first paragraph of the program determines that the input is not empty.

Whatever you enter is not empty.

As for the order of the program, the question is a bit inexplicable, or you are worrying about it.

Visual Basic (VB) is an event-driven programming language developed by Microsoft Corporation that includes an assisted development environment.

VB is the most spoken language in the world by any standard – not just the number of developers who praise VB but the number of developers who complain about it. It is derived from the basic programming language. VB has a graphical user interface (GUI) and a rapid application development (RAD) system, which makes it easy to connect to the database using DAO, RDO, ADO, or easily create ActiveX controls.

"Visual" refers to the method of developing a graphical user interface (GUI) - without having to write a lot of ** describing the appearance and position of interface elements, you can simply add pre-built objects to a point on the screen.

"Basic" refers to the Basic (BeginnersAll-Purpose SymbolicInstructionCode) language, one of the most widely used languages in the history of computing technology. Visual Basic is derived from the Basic programming language. With a graphical user interface (GUI) and a rapid application development (RAD) system, VB can easily connect to databases using DAO, RDO, ADO, or easily create ActiveX controls for efficient generation of type-safe and object-oriented applications.

Programmers can easily build an application quickly using the components provided by VB.

VB is the abbreviation of Visual Basic, which is a visual programming language. Pisearch is a simple and efficient tool for developing application software.

VB was first inherited by Microsoft from the early basic language burning material calendar, and added a visual program interface.

But the current VB and the basic language is not too related, because Microsoft in the process of upgrading VB, continue to add more syntax to VB, change the old syntax, and add object-oriented programming and other concepts, it can be said that the current VB program and the basic program, except for addition, subtraction, multiplication and division and for loop statement, can not find other the same characteristics.

However, Microsoft wouldn't have spent so much time pioneering and updating the VB language on its own. Microsoft used to develop a lot of programming products, but now only three programming languages are left: C, VB, and C++.

Microsoft can abandon many other less controversial programming languages, but has been reluctant to abandon the most controversial VB language. The answer can be found by analyzing Microsoft's historical trajectory.

The early C language function is recognized as powerful, especially in the development of large-scale computer software at that time, but in the development of enterprise business software, it is not very useful, in the small and micro computer market at that time, the simplest and least professional level of basic language is very popular for the development of application software, Microsoft is developed from that time, the earliest Microsoft application software development language is the basic language, which has made great contributions to Microsoft becoming a giant in the future.

This may make Microsoft realize that the success of the product is largely due to the low development cost and short development cycle, and the basic language undoubtedly has the most such potential, so Microsoft has been supporting the basic language and upgrading it countless times, so that the current VB2005 has been completely reborn.

Of course, today's VB language, I feel that its purpose is different from that of other languages, which generally pursue functional power and constantly expand the language syntax. The VB language pursues the efficiency of software development, the ease of learning of the programming language, and then the power of the language.

As a result, VB is always the most efficient and cost-effective development tool in the application software development market today (excluding non-Windows software).
