【正文】 ”和“運(yùn)行”菜單來查找和排除錯(cuò)誤。 算法是解題的步驟，我們可以把算法定義成解一確定類問題的任意一種特殊的方法。描述算法的方法有多種形式，例如自然語言和算法語言，各自有適用的環(huán)境和特點(diǎn)；③確認(rèn)算法 。要求算法中有待實(shí)現(xiàn)的運(yùn)算都是基本的，每種運(yùn)算至少在原理上能由人用紙和筆在有限的時(shí)間內(nèi)完成；③ 輸入。 算法在計(jì)算機(jī)上執(zhí)行運(yùn)算，需要一定的存儲空間存放描述算法的程序和算法所需 的數(shù)據(jù)，計(jì)算機(jī)完成運(yùn)算任務(wù)需要一定的時(shí)間。 。算法的復(fù)雜性的程度與運(yùn)行該算法所需要的計(jì)算機(jī)資源的多少有關(guān)，所需要的資源越多，表明該算法的復(fù)雜性越高；所需要的資源越少，表明該算法的復(fù)雜性越低。 而算法具有一定的特性，它包括：① 確定性。對算法的學(xué)習(xí)包括五個(gè)方面的內(nèi)容：① 設(shè)計(jì)算法。計(jì)算機(jī) 系統(tǒng)中的操作系統(tǒng)、語言編譯系統(tǒng)、數(shù)據(jù)庫管理系統(tǒng)以及各種各樣的計(jì)算機(jī)應(yīng)用系統(tǒng)中的軟件，都必須用一個(gè)個(gè)具體的算法來實(shí)現(xiàn)。比如當(dāng)設(shè)計(jì)界面時(shí)產(chǎn)生的窗體保存在擴(kuò)展名為 .frm 和 .frx 的窗體文件中。 VB 應(yīng)用程序代碼一般在“代碼編輯器”窗口編寫。早期的 Basic語言都是屬于解譯式的，因此可以一行一行地執(zhí)行，所以它可以立刻看到執(zhí)行的結(jié)果，對初學(xué)者來說這是很方便的設(shè)計(jì)。當(dāng)?shù)谝淮螁?VB 并打開一個(gè)新工程時(shí)，可以看到如圖所示的集成開發(fā)環(huán)境界面。學(xué)習(xí)版使編程人員很容易地開發(fā) Windows 和 Windows NT 的應(yīng)用程序。不論是初學(xué)者還是專業(yè)開發(fā)人員， VB 都為他們提供了一整套的工具，可以輕松方便的開發(fā)應(yīng)用程序。 Needs the resources are less, indicated that this algorithm the plexity is lower. The spatial resources, which puter’s resources, operate most importantly, needs the time which and the stored routine and the data need, the algorithm plexity has division time plexity and the spatial plexity. The algorithm carries out the operation on the puter, needs the data which certain storage space depositing description algorithm the procedure and the algorithm need, the puter pletes the operation task to require certain time. The procedure which writes according to the different algorithm places when on the puter operates, needs the time and the space are different, the algorithm plexity is needs the time and the spatial one kind of measure to the algorithm operation. The different puter its operating speed difference is very big, is weighing an algorithm the plexity to note this point. Regarding question, which assigns willfully, a profitable target which designs, the plex low algorithm is as far as possible when designs algorithm considered. Moreover, when the question, which assigns already when has many kinds of algorithms, an important criterion which choice plexity low, is when selects algorithm should follow. Therefore, the algorithm plex analysis or selects to the algorithm design has the important guiding sense and the use value. When discussion algorithm plexity, two questions need to clarify: (1) An 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。 Make web page use more VBScript script language sub collection of VB too at present. Utilize data of VB visit characteristic user can establish the data base to most data base forms including Microsoft SQL Server and other enterprises data base With the application program of front, and adjustable service end part. Utilize ActiveX(TM) technology, VB can use word processor, electronic data list he Windows function that application program offers extremely, Excel of Microsoft, Word of Microsoft, Even can use by VB specialty edition or enterprise application program and target that edition establish directly. The procedure that users established finally is a real .EXE file , can issue freely . 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 has offered the developing instrument with plete function 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. Section 2 integrated 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, piling 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 e and organize development of application program 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, q
