【正文】 through project, use project e 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. Section 3 Visual Basic language brief introductions Basic use and do the elementary highlevel language that used often most. Its full name is Beginner39。 s Allpurpose 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 have concept of structure either, one that is in procedure maintain and management have as much as other language problems. But backend Basic correct shorting of the above (such as Quick Basic), make it may used for and develop the largescaler procedure too. The language is the basic position, which forms VB procedure. VB has stipulated the form of sentences and function. 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 generally. editing machine of code is like the word processing software of a piece of height specialization, there are many easies function of writing VB code, Pursue to show [Example ExHello ]In code editing machine code that window written. “Editing machine of code” window Section 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. 2. 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 3. 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 editor39。s window of code pursued shows add codes “code editing machine” window 4. 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. 5. 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 within operate menus too. 6. Can produce by executive program For make procedure can break away from VB environment, order to bee next life through file producing project of menu but exec
