【文章內(nèi)容簡介】 erally formed of window body and vision frame of the button, menu, text standard WINDOWS interface of application program that VB 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 by each attributes of target in interfaceDemand and set up each attribute of target such as appearance, name， size of to interface of 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 the targets respond programming by procedure code procedure code of programming targetInterface 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, accepting external message, Add 學(xué)院畢業(yè)設(shè)計（論文）譯文專用紙 第 14 頁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 projectOne VB procedure one project, at the time of designing a application program, system will set up one be expanded and 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 example the window body produced when design interfaces is kept and being expanded and being the window body of the time of opening a project(file), this project relevant files load at the same and debugged by procedureOperate 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 produce by executive programFor make procedure can break away from VB environment, order to bee next life through” file“ producing project ” of menu but executive program(eyeful), Can carry out this file directly after produce, + executive program, and then through install guide bale all associated documents, Can run independently after installation under the environment of windows 9 x/2000 as a software puter system39。s any software, is by the every large or small each kind of software constituent constitution, defers to the specific algorithm to realize respectively, the algorithm quality direct decision realizes the software performance fit and unfit the algorithm with any method, what resources designs the algorithm to need, requires how many running time, how many storage space, how to determine an algorithm the quality, when realizes a software, is must give to puter system39。s operating system, the language piling system, the database management system as well as in various puter application system39。s software, must use each one concrete algorithm to , the algorithm design and 學(xué)院畢業(yè)設(shè)計（論文）譯文專用紙 第 15 頁the analysis are the puter science and a technical core algorithm is the problemsolving step, we may define the algorithm Cheng Jie a determination class question the random one special the puter science, the algorithm needs to use the puter algorithmic language to describe, the algorithm represents with the puter solves a kind of question precisely, the effective algorithm construction of data = procedure, solves one to assign may calculate or the solvable question, the different person may pile the different procedure, solves the identical problem, here has two problems: First, with putational method close related algorithm question。Second, programming technical the algorithm and the procedure has the close algorithm is a group has the poor rule, they had stipulated solves some specific type question a series of operations, is to the problem solving plan accurate and the plete an algorithm, generally must pass through stages and so on design, confirmation, analysis, code, test, debugging, algorithm study including five aspect contents: ① Design algorithm design work is impossible pletely the automation, should study the understanding already by the practice to prove that was the useful some basic algorithm design method, these basic design method was not only suitable for the puter science, moreover was suitable for domains and so on electrical engineering, operations research。② Expresses the description algorithm39。s method has many kinds of forms, for example the natural language and the algorithmic language, have the suitable environment and the characteristic respectively。③Confirms the algorithm confirmed the goal is causes the people to believe firmly that this algorithm can work unmistakably correctly, namely this algorithm has the correct algorithm describes with the puter algorithmic language, constitutes the puter program, the puter program moves on the puter, obtains the algorithm operation result。④ Parsing algorithmic analysis is requires how many puting time and the storage space to an algorithm makes the quota the parsing 學(xué)院畢業(yè)設(shè)計（論文）譯文專用紙 第 16 頁algorithm may forecast that what environment this algorithm does suit in moves effectively, to solves the identical question different algorithm validity to make the parison。⑤ Confirmation machine language description algorithm whether can calculate effectively, reasonable, must carry on the test to the procedure, the test order work and makes the space and time distribution map by the debugging to be the algorithm has certain characteristic, it includes: ① each kind of operation must have the determination significance, this kind of operation should carry out what kind of movement should not to have the ambiguity, the goal is clear。② the operation which in the algorithm waits for realizing is basic, each kind of operation can at least pletes in the principle by the human with the paper and the pen in the limited time。③ algorithm has 0 or the many inputs, before the algorithm operation starts gives the algorithm to need the data the starting value, these inputs are from the specific object set。④ for the algorithm operation result, an algorithm has or many outputs, the output has some kind of specific relational quantity with the input。⑤ Has algorithm always after carrying out had the poor step operation has terminated, namely this algorithm was may a first four characteristic group of rule not to be able to be called the algorithm, can only be called the putational process, the operating system is a putational proces
