Dev222 VB6与VB2005同心协力交互共存

课程内容概述 如果您还在使用VB6开发应用，可以通过这堂课了解如何借助VB2005的交互操作能力在VB6应用中添加新的功能。另外，您也可以感受到VB2005在生产效率上给您带来的巨大提升！

课程内容安排 Visual Basic 2005客户价值 Visual Basic 2005提高生产率的新功能 阐明对VB6的支持和升级路标 VB6与VB2005互操作

Visual Basic 对于核心业务的开发人员而言，Visual Basic 2005是开发Web, Windows, Office和Mobile应用程序最高效的工具!!

Visual Basic设计原则 提高生产效率 利用desktop的全部功能 使用Web容易和安全的方式部署 提供对平台的完全访问 减少一半的开发时间 减少超过一半的代码量 一次学习,到处使用 利用desktop的全部功能 使用Web容易和安全的方式部署 创建Windows Smart Client端的应用程序 提供对平台的完全访问 仍旧可以直接使用.NET框架

VB的新生产率研究报告 早期结果: 使用Windows Smart Client,提高20% 产品上市时间 目标：比较VB6和VB 2005生产率的差异 早期结果: 使用Windows Smart Client,提高20% 产品上市时间 使用ASP.NET Web client, 提高200%的产品上市时间 明显减少所需训练 最终结果很快将在msdn.com/vbrun上公布

利用现有投资 Reuse Skills Reuse Code Incremental Upgrade Support Statement: THESE ARE IMPORTANT POINTS TO MAKE Mainstream Support Ended March 31, 2005 Extended Support available through March 31, 2008 Custom Support contracts through 2012 VB6 applications will run on Windows Vista Reuse Skills: VB 6 developers find it easiest to upgrade to Visual Basic 2005. This enables them to reuse many of their existing development skills and familiarity with the development environment. VB 2005 returns oft-requested features like Edit and Continue but also adds more powerful ways to use the .NET Framework. Customer Citation: We’ve seen development organizations such as American Healthways get up to speed with development on VB .NET in under 30 days. This is far faster than it will be for that developer to move to a competing development environment. Reuse Code: Developers can reuse code through migration and our statistics have shown that automated migration will take care of 60% to 90% of the code involved in a migration. This isn’t a perfect solution and we need to be careful not to oversell it, but we have conducted migration labs where this has turned out to be an effective strategy for bringing code forward. Solomon – one of the Great Plains Applications –- is in the middle of upgrading a 5.9MM line application using a lot of this strategy. This won’t be ready (or public) until the end of the year but we will definitely be advertising and talking about this success. Incremental Migration This is one of the absolute key selling points vs. J2EE  developers do not need to complete the entire migration at one time. Well factored VB6 code can be used through COM Interop which means that upgrading an application can be stretched over time and can continue to leverage existing business logic. A VB6 application can be extended with VB .NET and a VB .NET application can leverage VB6 components. On the strategy aspect (upgrade skills first, write new .NET code now in VB2005, upgrade apps gradually), I heard some good feedback from the DPE leads this week:  We have to be very clear about the decisions BDMs need to make, because that will more effectively drive behavior and ultimately upgrade.  Even though it is a stick, our support policy change forces a decision to be made.  Obviously, we’d rather have carrots instead.  To that end, I recommend that we clearly say that now is the time to start writing new applications in .NET using VB 2005, and therefore skills upgrade is important to think about.  We should also clearly say that companies do not have to upgrade all their apps now.  This gives us an opportunity to talk about gradual “pay as you go” approaches using interop.  This gives us an opportunity to talk about gradual “pay as you go” approaches using interop. Incremental Upgrade

VB6 Support Policy 2005年3月31日结束Mainstream support 7年的免费支持, 远远长于竞争对手 Extended support直到2008年3月31日. Custom support直到2012年 保证VB6应用程序可以照常运行在Windows Vista上 VB6的运行时将作为Windows Vista的一部分发布 当Windows Vista发布后,将还有7年对VB6 runtime的免费支持
