VB offer study edition, the specialty edition and enterprise edition, use to satisfied with different development demands. Study edition make programming personnel develop Windows and Windows application program of NT very easily. The specialty edition to programming personnel of the specialty, Include studying all functions of edition in the specialty edition. Enterprise edition allow the professional personnel to establish strong distributed application program in the form of group. It includes all characteristics of the specialty edition. So can choose different editions according to different needs. 1.2integrated development environments

Integrated environment of VB call IDE, made up of a lot of parts , include title board, menu fence, tool fence, controlling part case, And window body window, engineering management device window, attribute window, code window and window body overall arrangement window body overall arrangement, etc. of designing etc.. Have covered all functions, such as design which develops the application program, editting, compiling and debugging, etc..

In VB, the application program calls the project too. When start VB and open a new project for the first time, can see and pursue integrated development environment interface that show.

Visual Basic Integrated development environment

VB come and organize development of application program through project, use project come and manage and form files of application program. One project uses the environment to make up by several window

bodies, standard module generally. The system manages project through the project menu, for instance add the window body, quote . System allow turn on and manage a lot of projects besides. 1.3Visual Basic language brief introductions

Basic use and do the elementary most. Its full name is Beginner' s All-purpose Symbolic Instruction Code, abbreviate as BASIC. As its name suggests, Basic one specially for language that beginner design, because it easy to learn easy to know, So the body is popular. Early Basic language to belong to and solve translating type, so can carry out line by line , So it can see the result carried out at once , this is a very convenient design for beginner. But it procedure maintain and management , which forms VB procedure. VB .

Grammar:

The sentence defines incantations [Sentence body]

Sentence define agree with and used in fixed function of sentence, sentence body appoint concrete content or want concrete operation that carry out of sentence. All set of sentence VB language, carry on with VB sentence organic association finish a certain specific function the procedure. Interface + procedure can solve a certain application problem.

VB application program code window write in\code editing machine\software of a piece of , there are many easies function of writing VB code, Pursue to show [Example Ex-Hello ]In\window written.

“Editing machine of code” window

1.4 develop the application program with Visual Basic

Use VB programming, design appearance of application program first generally, write every target procedure code or other treatment procedure of incident respectively, Work of programming should be light more.

The procedure of establishing the application program is as follows: Establish application program interface

The interface is the mutual bridge of user and procedure, Generally formed of window body and vision frame of the button, menu, text frameset. with standard WINDOWS interface of application program that VB establish. Require according to function of procedure and user and need of information interchange of procedure, Come to confirm that need those targets , plan the overall arrangement of the interface.

Design by each attributes of target in interface

Demand and set up each attribute of target such as appearance, name,, size of targeted. according to interface of planning.

Most attribute person who fetch can set up through the attribute window when design already, Too can set up revising when operating in procedure through programming in procedure code. Have the targets respond programming by procedure code

Respond procedure code of programming target

Interface determine appearance of procedure only, design window add codes through\code editing machine\soon after the interface, Realize some make the tasks, such as responding, information processing,etc. after accepting external message, Add code , realize some response, information processing that make after accepting external information task, As editor's

window of code pursued shows add codes

“code editing machine” window Keep project

One VB procedure one project, at the time of designing a application program, system will set up one be expanded and called. Project file of vbp, project file include all relevant information of file that project set up this, Keep project keep associated documents of project this at the same time. For example the window body produced when design interfaces is kept and being expanded and being called. Frm sum. In the window body of foxfire. At the time of opening a project( file), this project relevant files load at the same time.

Operate and debugged by procedure

Operate the procedure thoroughpin operate\selecting in the menu, when the mistake appears, VB system can offer information prompt can looked for and get rid of the mistake thoroughpin debug\menus too.

Can produce by executive program

For make procedure can break away from VB environment, order to become next life through\file\producing project 1.exe\of menu but executive program (eyeful), Can carry out this file directly after this. In produce, + executive program, and then through install guide bale all associated documents, Can run independently after installation under the environment of windows 9 x2000 as a software product.

In computer system's any software, is by the every large or small each kind of software constituent constitution, defers to the specific algorithm to
