VisualBasic语言与算法1991VisualBasic(VBVB2008Beta2(VB9)中文版。Visual意即可视的、可见的，指的是开发像windows操作系统的图形用户界面（GraphicUserInterface,GUI）外观和位置，只要把预先建立好的对象拖放到屏幕上相应的位置即可。Basic实际上是一个短语的缩写，这个短语就是Beginnersall_purposesymbolicinstructioncode，其中文意思为“初始者通用符号指令代码语言”。VisualBasic版适用于普通学习者及大多数使用VisualBasicWindows但是；专业版适用于计算机专业开发人员，包括了学习版的全部内容功能以及InternetVisualBasic1VisualBasicMicrosoftVisualBasicVB)Windows度、最简捷的工具之一。不论是初学者还是专业开发人员，VB都为他们提供了一整套的工具，可以轻松方便的开发应用程序。因此，VB一直被作为大多数电脑初学者的首选入门编程语言。中英文资料“Visual”指的是采用可视化的开发图形用户界面（GUI）的方法，一般不需要应位置即可方便图形设计图形用户界面；“Basic”指的是BASICVBBAISCVB是Microsoft的一种通用程序设计语言，它包括在MicrosoftExcelMicrosoftAccessWindowsVBAVBVBScriptVBVBMicrosoftSQLServerActiveX(TM)技术，VBMicrosoftWordMicrosoftExcelWindowsVB用户最终创建的程序是一个真正的.EXE文件，可以自由发布。VBWindowsWindowsNT不同的需要来选择不同的版本。第2节集成开发环境VBIDE，由多个部分组成，包含了标题栏、菜单栏、工具栏、控布局等。覆盖了开发应用程序的设计、编辑、编译和调试等所有功能。VBVB如图所示的集成开发环境界面。VisualBasic集成开发环境VB3VisualBasicBasic是最常被用来做入门使用的高级语言。它的全名是Beginner’sAll-purposeSumbolicInstructionCode，简称为BASIC。顾名思义，Basic就是中英文资料BasicBasic（Quick使得它也可以用来开发较大型的程序。VBVB语法：语句定义符[语句体]VBVB序。界面+程序就能解决某个应用问题。VBVBEx-Hello]码编辑器”窗口编写的代码。“代码编辑器”窗口第4节用VisualBasic开发应用程序使用VB编程，一般先设计应用程序的外观，然后再分别编写各对象事件的程序代码或其他处理程序，编程的工作要轻松多。创建应用程序的步骤如下：创建应用程序界面VBWINDOWS之间的信息交流的需要，来确定需要那些对象，规划界面的布局。设计界面上各个对象的属性根据规划的界面要求设置各个对象的属性，比如对象的外貌、名称、颜色、大小等。大多数属性取值既可以在设计时通过属性窗口来设置，也可以在程序代码中通过编程在程序运行时设置修改。编程对象响应的程序代码界面仅仅决定了程序的外观，设计完界面后就要通过“代码编辑器”窗口来添加代码，实现一些在接受外界信息后作出响应、信息处理等任务，添加中英文资料码编辑窗口所示“代码编辑器”窗口保存工程一个VB程序就是一个工程，在设计一个应用程序时，系统会建立一个扩展名为.vbp为.frm.frx（文件）同时被装载。行和调试程序通过“运行”菜单中的选项来运行程序，当出现错误时，VB系统可以提供信息提示也可通过“调试”和“运行”菜单来查找和排除错误。生成可执行程序VB1.exe”生成可执行程序（.exe文件，此后即可直接执行该文件。在生成可+执行程序后，windows环境下安装后独立运行VB的数据库编程方面按其难易程度可分为三类(由易到难);●使用数据库控制项和绑定控制项●使用数据库对象变量进行编程●直接调用ODBC2.0API在使用VB进行数据库编程时,通常,会首先选择三种基本方法之一来进行数据库应用程序的方案设计,现在就将以上三种设计方法的适应范围及其优缺点进行一个比较。使用数据库控制项和绑定控制项优点它是三种方法中编码量最小的不必了解CDBC2.0API的细节允许使用标准的和第三方厂商制订的控制项简化了错误处理支持所有的动态集方法及属性中英文资料缺点不能存取快照对象(snapshop)对象或表格对象(都属于记录集对象)不能存取数据库集合,比如表定义(TableDefs)字段(Fieds),索引(Indexes)及查询定义(QueryDefs)ODBC2.0不能进行真正的事务处理有限的错误诊断功能应用对中小规模的数据库表(通常少于一千条记录)只进行简章的浏览操作基本SQL查询所对应的结果集长度有限(通常结果集的记录数小于一百,这些记录从一个或两个长度有限的表中检索出来)应用程序的数据输入/输出项较少(通常只涉及一个或两个长度有限的表、并且表中的字段数在10个左右且不具有关系完整性限制使用数据库对象变量进行编程优点可以在程序中存取ODBC2.0的管理函数可以控制多种记录集类型:Dynaset、SnapshopTable可以存取存储过程和查询动作TableDefs、Fields、IndexesQueryDefs具有真正的事务处理能力,包括启动事务(Begintrans)、提交事务(CommitTrans)及回滚事务(Rollback)缺点比使用数据控制项的方法编码量较大只能进行间接的错误处理和错误恢复对每个数据库操作没有细粒度的控制对结果集和包含结果集的内丰资源的操作受到限制同直接使用ODBC2.0API函数的方法相比性能较低应用应用程序需要在执行期间动态地建立表、字段及索引.应用程序涉及同步更新几张表(但在逻辑上保持一致性)的复杂事务Dynaset(FORMS)SnapshotsTables,中英文资料这里是设计要考虑的关键应用程序的表非常大,多于1000条记录应用程序具有复杂的数据输入/输出项,它涉及许多内部相关的字段并且包括数据库参照完整性或一致性规则应用程序需要执行一些额外的操作和对结果集的查询后处理,尤其是需要很高的数据格式化显示ODBC应用程序需要在执行期间“显示”数据库的基本结构应用程序需要使用复杂的多码索引方式来检索或更新记录ODBC2.0API优点可以直接参与结果集的开发、管理及规范化对结果集游标提供了更多的控制,并且提供了更多的游标类型和执行动作能够确定ODBC驱动程序及SQL的一致性级别可以更好地控制Windows的执行调度及资源利用其他方面同其他方法差不多,因此这种方法很可能具有最好的性能缺点较其他两种方法需要大量的代码代码复杂并且要求程序员具有编制API调用的经验VisualBasic现的错误所造成的后果会非常严重应用/都能够准确地解决可能出现的系统错误和失败应用程序强调资源使用,这里如何对内存、网络服务器资源进行直接控制是首要的考虑因素应用程序使用超大规模数据库,例如数据库表可能包含几万或几十万条记录中英文资料码、测试、调试、计时等阶段。对算法的学习包括五个方面的内容：①设计算法。算法设计工作是不可能完全自动化的，应学习了解已经被实践证明是有用的一些基本的算法设计方法，这些基本的设计方法不仅适用于计算机科学，而且适用于电气工程、运筹学等领域。②表示算法。描述算法的方法有多种形式，例如自然语言和算法语言，各自有适用的环境和特点。④分析算法。算法分析是对一个算法需要多少计算时间和存储空间作定量的分的不同算法的有效性作出比较。⑤验证算法。用计算机语言描述的算法是否可计算、有效合理，须对程序进行测试，测试程序的工作由调试和作时空分布图组成。而算法具有一定的特性，它包括：①确定性。算法的每一种运算必须有确定的意义，该种运算应执行何种动作应无二义性，目的明确。②能行性。要求算法中有待实现的运算都是基本的，每种运算至少在原理上能由人用纸和笔在有限的时间内完成。③输入。一个算法有0个或多个输入，在算法运算开始之前给出算法所需数据的初值，这些输入取自特定的对象集合。④输出。作为算法运算的结果，一个算法产生一个或多个输出，输出是同输入中英文资料有某种特定关系的量。⑤有穷性。一个算法总是在执行了有穷步的运算后终止，即该算法是可达的。算过程并不停止，而是处于等待状态。意到这一点。中英文资料原文：VisualBasiclanguageandarithmeticTheUnitedStateslaunchedtheMicrosoftVisualBasic(maybereferredtoisthelatestversionofthecurrentVB2008Beta2(VB9)Chineseversion.Visualmeaningthevisual,visible,referringtothedevelopmentofoperatingsystemslikewindowsgraphicaluserinterface(GraphicUserInterface,GUI)method,itdoesnotneedtopreparealargenumbercodetodescribetheappearanceoftheinterfaceelementsandlocation,aslongasthepre-Theestablishmentofgooddraganddropobjectsonthescreencorrespondingtothelocation.Basicisactuallyanabbreviationofthephrase;thisphraseisBeginnersall-purposesymbolicinstructioncode,theChinesemeaning"totheinitialdirectiveGMsymbolcodelanguage."VisualBasiclearning,ProfessionalEditionandEnterpriseEditionversionstomeetthedifferentneedsofthedevelopment.StudyandapplytotheordinaryversionofthemajorityoflearnersandtheuseofVisualBasicdevelopmentofthegeneralstaffofWindowsapplications,but;professionalversioncomputerprofessionaldevelopmentofstaff,includingthestudyoffunctionalversionofthefullcontentcontrolandInternetdevelopmenttoolssuchasadvancedfeatures,Enterprisecontainnotonlyalltheprofessionalofthecontent,thereareautomatedtoolssuchasComponentManager,professionalprogrammerstomakethedevelopmentofapowerfulgroupessenceofdistributedapplications.VisualBasicSection1thesummaryofVisualBasicMicrosoftVisualBasic,(abbreviateVB)astoolthemostofapplicationprogramoneofunderWindowsoperatingplatform.Nomatterbeginnerorprofessionaldeveloper,VBhasallofferedawholesetoftoolstothem,中英文资料Developmentapplicationprogramt
