VisualC++6.0踩坑记录---在Win10下安装VisualC++6.0安装成功后。。。
VisualC++6.0踩坑记录---在Win10下安装VisualC++6.0安装成功后。
前⾔： 为了更好的学习C及C++，前段时间下载了Microsoft Visual C++ 6.0（以下简称VC6），原因是VC6具有查看反汇编代码、监视内存、寄存器等功能，并且因为本⼈正在学习滴⽔逆向海哥的课程，他⽤的就是VC6，我也懒得折腾，就⽤了和他⼀样的编译器。
其实他教给我的最让我受益的，就是他对于编程语⾔的理解⾓度：从编译器的⾓度去理解C及C++语⾔，从编译器的⾓度理解指令在底层是如何被编译器处理的。
借⽤海哥的话：只有从编译器的⾓度去理解C及C++，才能领悟到这门语⾔的真谛，才能在这条路上没有瓶颈没有上限。
（跑题了。
） 在多个软件论坛及⽹站上下载了不同版本的VC6，发现了⼀个共性问题：在点击“打开”按钮时，VC6会卡顿⼀下然后闪退，去⽹上查找了原因。
发现VC6作为微软1998年推出的⼀款C++编译器（⽼古董级别），存在诸多兼容性问题，例如在Windows XP（调试模式会出现静态变量的值不显⽰，需要靠打补丁解决），Windows7（兼容性问题，同Windows10），Windows8（需要通过修改原MSDEV.exe⽂件名，并改兼容性才能解决）。
⽽有⼈提出VC6在Win7和Win10上都存在的不兼容现象，通过改变兼容模式即可解决。
于是我按照⽹上提供的操作⽅法，右键单击VC6的快捷⽅式，点击属性，在“兼容性”⼀栏中设置兼容模式勾选“以兼容模式运⾏这个程序”，然后在下拉菜单栏中选择如图“Windows XP(Service Pack 3)”，点击确定即可设置完成。
可是设置之后进⼊VC6仍然闪退，于是我⼜尝试了“兼容模式”下拉栏中所有的模式，发现全部都没能解决这个问题，于是我放弃了这个⽅法。
既然更改兼容模式没办法解决这个问题，只好另辟蹊径，刚好此时在CSDN上看到了⼀个解决办法，这⾥挂上⽹址：⼤家可以⾃⾏下载此链接⾥提供的.dll⽂件（已编译版本）（百度⽹盘下载）操作步骤：1.把下载好的FileTool.dll⽂件放⼊D:\Microsoft Visual Studio\Common\MSDev98\AddIns下（这⾥是我的VC6的安装路径，⼤家根据⾃⼰的安装路径拷贝⽂件即可）2.⽤管理员⾝份打开DOS，⼿动注册FileTool.dll3.打开VC6--⼯具--定制--附加项和宏⽂件，勾选FileTool Developer Studio Add-in，点击关闭即可。

Microsoft Visual Basic 6.0升级到 Microsoft VisualBasic
VB6升级方案1．Microsoft Visual Basic Upgrade Wizard使用Visual 中的Microsoft Visual Basic Upgrade Wizard的自动转换功能。
该转换在大多数项目中不能100%的升级到.NET，其中有95%可以被转换，剩余5%需要手工修改。
因为他的对象模型与Visual Basic6.0中的对象模型有很大的不同。
而且.NET并不能完全支持VB6的功能，比如DAO和RDO的数据绑定、事件参数、某些函数等。
因此在转换的过程中，还需要理解VB6的编码方式与.NET 方式的区别。
这些区别我们可以参考《Upgrading Microsoft Visual Basic6.0to Microsoft Visual 》完整技术指南，该指南是由一家在Visual Basic升级方面具有丰富经验的公司Artinsoft 以及Visual Basic Upgrade Wizard和Visual Basic Upgrade Wizard Companion的开发人员联合编写的，其中在第二章节写出了Visual Basic6and Visual Differences的差别。
使用Microsoft Visual Basic Upgrade Wizard的优点：1、免费，集成在Visual Studio里能够较好的转换，转换后能生成一个Upgrade Report文档，里面包含了升级过程的信息和需要解决的问题列表，警告列表等。
使用Microsoft Visual Basic Upgrade Wizard的缺点：1、转换语言单一，只能转换VB。
需要只能在Visual Studio2005下面转换，如需转换高版本需要在转换一次。
2、并不能百分百转换。
还有部分代码需要手工转换。
2．控制台在控制台下转换，转换效果与Visual 中的Microsoft Visual Basic Upgrade Wizard的自动转换功能一样。
外文翻译--准备将 Visual Basic 6.0 应用程序升级到 Visual Basic
外文原文Preparing Your Visual Basic 6.0 Applications for the Upgrade toVisual Basic .NETOverviewThis document provides recommendations for developers using Microsoft® Visual Basic® who are planning to upgrade their applications to Microsoft Visual Basic .NET.Visual Basic .NET will open and upgrade Visual Basic 6.0 projects to Visual Basic .NET technologies, but in most cases you will need to make some modifications to your projects after bringing them into Visual Basic .NET. The purpose of this document is to recommend how to design and implement your current Visual Basic projects to minimize the number of changes you will need to make when they are upgraded to Visual Basic .NET. Where appropriate, we use new language constructs; however, this document is not intended to be a Visual Basic .NET language reference. What Is Visual Basic .NET?Visual Basic .NET is the next version of Visual Basic. Rather than simply adding some new features to Visual Basic 6.0, Microsoft has reengineered the product to make it easier than ever before to write distributed applications such as Web and enterprise n-tier systems. Visual Basic .NET has two new forms packages (Windows Forms and Web Forms); a new version of ADO for accessing disconnected data sources; and streamlined language, removing legacy keywords, improving type safety, and exposing low-level constructs that advanced developers require.These new features open new doors for the Visual Basic developer: With Web Forms and ADO .NET, you can now rapidly develop scalable Web sites; with inheritance, the language now truly supports object-oriented programming; Windows Forms natively supports accessibility and visual inheritance; and deploying your applications is now as simple as copying your executables and components from directory to directory.Visual Basic .NET is now fully integrated with the other Microsoft Visual Studio .NET languages. Not only can you develop application components in different programming languages, your classes can now inherit from classes written in other languages using cross-language inheritance. With the unified debugger, you can now debug multiple language applications, irrespective of whether they are running locally or on remote computers. Finally, whatever language you use, the Microsoft .NET Framework provides a rich set of APIs for Microsoft Windows® and the Internet.Why Is Visual Basic .NET Not 100% Compatible?There were two options to consider when designing Visual Basic .NET—retrofit the existing code base to run on top of the .NET Framework, or build from the ground up, taking full advantage of the platform. To deliver the features most requested by customers (for example, inheritance, threading), to provide full and uninhibited access to the platform, and to ensure that Visual Basic moves forward into the next generation of Web applications, the right decision was to build from the ground up on the new platform.For example, many of the new features found in Windows Forms could have been added to the existing code base as new controls or more properties. However, this would have been at the cost of all the other great features inherent to Windows Forms, such as security and visual inheritance.One of our major goals was to ensure Visual Basic code could fully interoperate with code w ritten in other languages, such as Microsoft Visual C#™ or Microsoft Visual C++®, and enable the Visual Basic developer to harness the power of the .NET Framework simply, without resorting to the programming workarounds traditionally required to make Windows APIs work. Visual Basic now has the same variable types, arrays, user-defined types, classes, and interfaces as Visual C++ and any other language that targets the Common Language Runtime; however, we had to remove some features, such as fixed-length strings and non-zero based arrays from the language.Visual Basic is now a true object-oriented language; some unintuitive and inconsistent features like GoSub/Return and DefInt have been removed from the language.The result is a re-energized Visual Basic, which will continue to be the most productive tool for creating Windows-based applications, and is now positioned to be the best tool for creating the next generation Web sites.Upgrading to Visual Basic .NETVisual Basic .NET enables a fundamental shift from traditional Windows development to building next-generation Web and n-tier applications. For this reason, your code will need to be upgraded to take advantage of Visual Basic .NET.This happens automatically when you open a Visual Basic 6.0 project in Visual Basic .NET: the Upgrade Wizard steps you through the upgrade process and creates a new Visual Basic .NET project (your existing project is left unchanged). This is a one-way process; the new Visual Basic .NET project cannot be opened in Visual Basic 6.0.When your project is upgraded, the language is modified for any syntax changes and your Visual Basic 6.0 Forms are converted to Windows Forms. In most cases, you will have to make some changes to your code after it is upgraded. This is required because certain objects and language features either have no equivalent in Visual Basic .NET, or have an equivalent too dissimilar for an automatic upgrade. After the upgrade, you may also want to change your application to take advantage of some of the new features in Visual Basic .NET.Working with Both Visual Basic 6.0 and Visual Basic .NETVisual Basic .NET supports upgrading Visual Basic 6.0 projects; if you have a project written in Visual Basic versions 1 to 5, we recommend you load it into VB6 (choosing to upgrade Microsoft ActiveX® controls), compile, and save the project before upgrading it to Visual Basic .NET.Both Visual Basic .NET and Visual Basic 6.0 can be installed on the same computer and run at the same time. Likewise, applications written in Visual Basic .NET and Visual Basic 6.0 can be installed and executed on the same computer.Components written in Visual Basic .NET can interoperate with COM components written in earlier versions of Visual Basic and other languages. For example, you can drop an ActiveX control written in Visual Basic 6.0 onto a Visual Basic .NET Windows Form, use a Visual Basic 6.0 COM object from a Visual Basic .NET class library, or add a reference to a Visual Basic .NET library to a Visual Basic 6.0 executable.Components compiled with Visual Basic .NET have subtle run-time differences from components compiled with Visual Basic 6.0. For starters, because Visual Basic .NET objects are released through garbage collection, when objects are explicitly destroyed, there may be a lag before they are actually removed from memory. There are additional differences such as the variant/object changes described later in this document. The combined result of these differences is that Visual Basic .NET applications will have similar but not identical run-time behavior to Visual Basic 6.0 applications.In addition, Visual Basic .NET makes binary compatibility between Visual Basic .NET components and those in Visual Basic 6.0 unnecessary. Components now have a more robust versioning and deployment system than ever before, files can be deployed by simply copying to a directory (no more RegSvr32), and upgrading to a new version of a component is as simple as replacing the old file with a new file. All you have to do is ensure classes and methods are compatible with the previous version.Architecture RecommendationsThe .NET platform improves upon previous architectures, and adds greater support for scalability and distributed applications though disconnected data access, HTTP-based message transport, and file-copy based deployment (no more registering of components). To best take advantage of these features, you should design your applications with an architecture similar to that you would use in Visual Basic .NET. Browser-based ApplicationsVisual Basic 6.0 and Microsoft Visual Studio® 6.0 offered several technologies for creating browser-based Internet and intranet applications:•Webclasses•DHTML projects•ActiveX documents•Active Server Pages (ASP)Visual Basic .NET introduces , an enhanced version of ASP, and adds to the architecture with Web Forms, which are HTML pages with Visual Basic events. The architecture is server-based.Below is a list of recommendations and architectural suggestions for developing Visual Basic 6.0 browser-based applications that will most seamlessly migrate to Visual Basic .NET projects:•We recommend you use the Microsoft multi-tier architectureguidelines to create your applications, create the interface with ASP, and useVisual Basic 6.0 or Visual C++ 6.0 COM objects for your business logic.ASP is fully supported in Visual Basic .NET, and you can continue toextend your application using ASP, , and Web Forms. The VisualBasic 6.0 and Visual C++ 6.0 business objects can either be used withoutmodification or upgraded to Visual Studio .NET.•DHTML applications contain DHTML pages and client-side DLLs.These applications cannot be automatically upgraded to Visual Basic .NET.We recommend you leave these applications in Visual Basic 6.0.•ActiveX documents are not supported in Visual Basic .NET, and likeDHTML projects, cannot be automatically upgraded. We recommend youeither leave your ActiveX document applications in Visual Basic 6.0 or,where possible, replace ActiveX documents with user controls.•Visual Basic 6.0 ActiveX documents and DHTML applications caninteroperate with Visual Basic .NET technologies. For example, you cannavigate from a Visual Basic .NET Web Form to a Visual Basic 6.0DHTML page, and vice–versa.•Webclasses no longer exist in Visual Basic .NET. Webclassapplications will be upgraded to ; however, you will have to makesome modifications after upgrading. Existing Webclass applications caninteroperate with Visual Basic .NET Web Forms and ASP applications, butfor new projects we recommend you use the Windows DNA platform ofASP with Visual Basic 6.0 business objectsClient/Server ProjectsVisual Basic 6.0 offered several technologies for creating client/server applications:•Visual Basic Forms•Microsoft Transaction Server (MTS)/COM+ middle-tier objects•User controlsIn Visual Basic .NET, there is a new form package: Windows Forms. Windows Forms has a different object model than Visual Basic 6.0 Forms, but is largely compatible. When your project is upgraded, Visual Basic Forms are converted to Windows Forms.Visual Basic .NET improves support for developing middle-tier MTS and COM+ component services components. Using the unified debugger, you can step from a client application into an MTS/COM+ component and back to the client. You can also use the unified debugger to step through Visual Basic 6.0 MTS/COM+ components (providing they are compiled to native code, with symbolic debug information and no optimizations).Visual Basic .NET also introduces a new middle-tier component, Web Services. Web Services are hosted by , and use the HTTP transport allowing method requests to pass through firewalls.They pass and return data using industry standard XML, allowing other languages and other platforms to access their functionality. Although they do not support MTS transactions, you may want to change your MTS/COM+ components to Web Services in cases where you do not need distributed transactions but still want to interoperate with other platforms.When your project is upgraded, user controls are upgraded to Windows controls; however, custom property tag settings and accelerator keys assignments will not be upgraded.Single-tier ApplicationsVisual Basic 6.0 supported building several types of single-tier applications: •Single-tier database applications•Visual Basic add-ins•Utility programs and gamesSingle-tier database applications are typified by a Visual Basic application storing data in an Microsoft Access database. These applications will upgrade to Visual Basic .NET with some limitations (see the Data section later in this document).Now that the Visual Basic .NET IDE is a fully integrated part of the Visual Studio .NET IDE,the Visual Basic .NET has a new language-neutral extensibility model. Visual Basic .NET add-ins are now Visual Studio .NET add-ins, and you can automate and add features to any language in Visual Studio .NET. For example, you can write a Visual Basic .NET add-in that re-colors a Visual C# Windows Form or adds comments to a Visual Basic class. In order to provide this functionality, Visual Basic .NET has moved away from the old extensibility model, and you will need to change thevery extensibility objects in your application to take advantage of the new features.Many applications fall under the category of Utility programs.Utility applications that manipulate files, registry settings, and the like will often upgrade without requiring any additional changes. After upgrading, there are many new features you can take advantage of, such as exception handling in the language to capture file system errors, and using .NET Framework registry classes to manipulate the registry. One thing to be aware of is that applications relying on specific performance characteristics of Visual Basic 6.0, such as arcade games, will probably require some modifications because Visual Basic .NET has different many performance characteristics. For games support in Visual Basic .NET, you can useMicrosoft DirectX® 7, or the new version of GDI. GDI+ introduces many new features, including Alpha blending support for all 2-D graphics primitives, anti-aliasing, and expanded support for image file formats.DataVisual Basic 6.0 offered several types of data access:•ActiveX Data Objects (ADO)•Remote Data Objects (RDO)•Data Access Objects (DAO)Visual Basic .NET introduces an enhanced version of ADO called ADO .NET. ADO .NET targets disconnected data, and provides performance improvements over ADO when used in distributed applications. ADO .NET offers read/write data binding to controls for Windows Forms and read-only data binding for Web Forms.DAO, RDO, and ADO can still be used in code from Visual Basic .NET, with some trivial modifications (covered in the language section of this document). However, Visual Basic .NET does not support DAO and RDO data binding to controls, data controls, or RDO User connection. We recommend that if your applications contain DAO or RDO data binding you either leave them in Visual Basic 6.0 or upgrade the DAO and RDO data binding to ADO before upgrading your project to Visual Basic .NET, as ADO data binding is supported in Windows Forms. Information on how to do this is available in the Visual Basic 6.0 Help.In summary, we recommend using ADO in your Visual Basic 6.0 projects. UpgradingWhen your code is upgraded, Visual Basic .NET creates a new upgraded project and makes most of the required language and object changes for you. The following sections provide a few examples of how your code is upgraded.Variant to ObjectPrevious versions of Visual Basic supported the Variant datatype, which could be assigned to any primitive type (except fixed-length strings), Empty, Error, Nothingand Null. In Visual Basic .NET, the functionality of the Variant and Object datatypes is combined into one new datatype: Object. The Object datatype can be assigned to primitive datatypes, Empty, Nothing, Null, and as a pointer to an object.When your project is upgraded to Visual Basic .NET, all variables declared as Variant are changed to Object. Also, when code is inserted into the editor, the Variant keyword is replaced with Object.Visual Basic Forms to Windows FormsVisual Basic .NET has a new forms package, Windows Forms, which has native support for accessibility and has an in-place menu editor. Your existing Visual Basic Forms are upgraded to Windows Forms.InterfacesIn previous versions of Visual Basic, interfaces for public classes were always hidden from the user. In Visual Basic .NET, they can be viewed and edited in the Code Editor. When your project is upgraded, you choose whether to have interface declarations automatically created for your public classes.Upgrade Report and CommentsAfter your project is upgraded, an upgrade report is added to your project, itemizing any changes you will need to make to your upgraded code. Additionally, comments are added to your code to alert you to any potential problems. These comments show up automatically in the Visual Studio .NET Task List. Programming RecommendationsThis section provides recommendations for how you should write code to minimize the changes you will need to make after upgrading your project to Visual Basic .NET.Use Early-BindingBoth Visual Basic 6.0 and Visual Basic .NET support late-bound objects, which is the practice of declaring a variable as the Object datatype and assigning it to an instance of a class at run time. However, during the upgrade process, late-boundobjects can product introduce problems when resolving default properties, or in cases where the underlying object model has changed and properties,methods, and events need to be converted. For example, suppose you have a Form called Form1 with a label called Label1.In Visual Basic .NET Windows Forms, the Caption property of a label control is now called Text. When your code is upgraded, all instances of the Caption property are changed to Text, but because a late-bound object is type-less, Visual Basic cannot detect what type of object it is, or if any properties should be translated. In such cases, you will need to change the code yourself after upgrading.Visual Basic .NET supports overloading functions based on parameter type. Visual Basic .NET determines which function to call based on the parameter type. If you pass an integer to Environ(), the integer version is called; if you pass a string, then the string version is called. Code that passes a Variant or Object datatype to an verloaded function may cause a compile or runtime error. Using an explicit conversion, as in the following example, will mean your code will work as intended after it is upgraded to Visual Basic .NET.Using explicit conversions of late bound objects is good coding practice. It makes the intention of the code easy to determine, and makes it easier for you to move your project to Visual Basic .NET.Use Date for Storing DatesEarlier versions of Visual Basic supported using the Double datatype to store and manipulate dates. You should not do this in Visual Basic .NET, because dates are not internally stored as doubles.The .NET framework provides the ToOADate and FromOADate functions to convert between doubles and dates. However, when your project is upgraded to Visual Basic .NET, it is difficult to determine the intention of code that uses doubles to store dates.To avoid nnecessary modifications to your code in Visual Basic .NET, always use the Date datatype to store dates.Resolve Parameterless Default PropertiesIn Visual Basic 6.0, many objects expose default properties, which can be omitted as a programming shortcut.In the late-bound example, the default property is resolved at run time, and the MsgBox displays the value of the default property of the TextBox as Text1.Visual Basic .NET does not support parameterless default properties, and consequently does not allow this programming shortcut. When your project is upgraded, Visual Basic .NET resolves the parameterless default properties, but late-bound usages that rely on run-time resolution cannot be automatically resolved. In these cases, you will have to change the code yourself. An additional complication is that many libraries implement default properties using a property called _Default. _Default acts as a proxy, passing calls to the real default property. So, when your project is upgraded, some default properties will be resolved to _Default. The code will still work as usual, but it will be less understandable than code written explicitly using the actual property.中文译文准备将 Visual Basic 6.0 应用程序升级到 Visual 概述本文档为使用Microsoft® Visual Basic® 的开发人员提供有关将应用程序升级到 Microsoft Visual 的建议。
Visual Basic 6MSComm控件
Visual Basic6.0(以下简称VB)是一种功能强大、简单易学的程序设计语言。
它不但保留了原先Basic语言的全部功能，而且还增加了面向对象程序设计功能。
它不仅可以方便快捷地编制适用于数据处理、多媒体等方面的程序，而且利用ActiveX控件MSComm还能十分方便地开发出使用计算机串口的计算机通信程序。
本文结合计算机通信的两个例子，详细介绍如何在VB中使用MSComm控件。
处理方式MSComm控件提供了两种处理通信的方式：一种为事件驱动方式，该方式相当于一般程序设计中的中断方式。
当串口发生事件或错误时，MSComm控件会产生OnComm事件，用户程序可以捕获该事件进行相应处理。
本文的两个例子均采用该方式。
另一种为查询方式，在用户程序中设计定时或不定时查询MSComm控件的某些属性是否发生变化，从而确定相应处理。
在程序空闲时间较多时可以采用该方式。
常用属性和方法利用MSComm控件实现计算机通信的关键是理解并正确设置MSComm控件众多属性和方法。
以下是MSComm 控件的常用属性和方法：●Commport：设置或返回串口号。
●Settings：以字符串的形式设置或返回串口通信参数。
●Portopen：设置或返回串口状态。
●InputMode：设置或返回接收数据的类型。
●Inputlen：设置或返回一次从接收缓冲区中读取字节数。
●InBufferSize：设置或返回接收缓冲区的大小，缺省值为1024字节。
●InBufferCount：设置或返回接收缓冲区中等待计算机接收的字符数。
●Input：从接收缓冲区中读取数据并清空该缓冲区，该属性设计时无效，运行时只读。
●OutBufferSize：设置或返回发送缓冲区的大小，缺省值为512字节。
●OutBufferCount：设置或返回发送缓冲区中等待计算机发送的字符数。
●Output：向发送缓冲区发送数据，该属性设计时无效，运行时只读。
●Rthreshold：该属性为一阀值。

VB6升级方案
1．Microsoft Visual Basic Upgrade Wizard
使用Visual Studio .NET 中的Microsoft Visual Basic Upgrade Wizard 的自动转换功能。
该转换在大多数项目中不能100%的升级到.NET，其中有95%可以被转换，剩余5%需要手工修改。
因为他的对象模型与Visual Basic 6.0 中的对象模型有很大的不同。
而且.NET并不能完全支持VB6的功能，比如DAO和RDO的数据绑定、事件参数、某些函数等。
因此在转换的过程中，还需要理解VB6的编码方式与.NET 方式的区别。
这些区别我们可以参考《Upgrading Microsoft Visual Basic 6.0 to Microsoft Visual
Basic .NET》完整技术指南，该指南是由一家在Visual Basic 升级方面具有丰富经验的公司Artinsoft 以及Visual Basic Upgrade Wizard和Visual Basic Upgrade Wizard Companion的开发人员联合编写的，其中在第二章节写出了Visual Basic 6 and Visual Basic .NET Differences的差别。
使用Microsoft Visual Basic Upgrade Wizard的优点：
1、免费，集成在Visual Studio 里能够较好的转换，转换后能生成一个Upgrade Report 文档，里面包含了升级过程的信息和需要解决的问题列表，警告列表等。
使用Microsoft Visual Basic Upgrade Wizard的缺点：
1、转换语言单一，只能转换VB。
需要只能在Visual Studio 2005 下面转换，如需转换高版本需要在转换一次。
2、并不能百分百转换。
还有部分代码需要手工转换。
2．控制台
在控制台下转换，转换效果与Visual Studio .NET 中的Microsoft Visual Basic Upgrade Wizard 的自动转换功能一样。
找到C:\Program Files\Microsoft Visual Studio 8\VB\VBUpgrade
CD C:\Program Files\Microsoft Visual Studio 8\VB\VBUpgrade>vbupgrade /? 查看帮助
转换样例:vbupgrade c:\Project1.vbp /Out c:\。
3．VBUC
使用ArtinSoft’s Visual Basic Upgrade Companion (VBUC.5.0.exe)工具转换。
VBUC优点：
1、能够转换VB 、C#语言，也能转换到Visual Studio 2005、Visual Studio 2008、Visual Studio 2010环境下面。
2、能够加速项目迁移，大大的降低了手工转换代码
3、拥有图形界面
4、在数据访问方面能够自动转换成
5、对第三方库和ActiveX控件有较好的处理方式。
VBUC缺点：
1、VBUC需要付费，免费版只能转换的代码在10,000行
2、也不能100%的完全转换。
在升级过程中也可以借助使用Basic 6.0 Upgrade Assessment Tool工具，它这个工具能够识别常见的升级问题以及估算升级Visual Basic 6.0 代码所需的成本和人力。
另外值得一提的是在项目升级之前，还有一些分析工具能够帮助我们来理解项目Aivosto 的Project Analyzer 和Visual Basic 6.0 Code Advisor
Project Analyzer：工具能够进行代码审查，通过树列表显示项目之间的关系，类关系结构图，生成问题列表显示错误和潜在的缺陷。
Visual Basic 6.0 Code Advisor:该工具相当于VB6企业版的一个插件，在安装前需要先安装.net Freamwork 1.0 和VB6企业版，安装后会自动集成在VB6企业版里。
他能够用于检查代码，以确保它符合预定的编码标准，还可以用于提醒您注意可能会阻止您的应用程序成功升级到Visual Basic .NET 的问题。
Code Advisor 并不能发现所有升级问题，但是根据设计它可帮助找到最常见的问题并加速升级过程。
