如何使用和掌握Sybase PowerBuilder .NET V12.0以及如何将旧版本迁移到它
我是 Sybase PowerBuilder 的新手，我注意到它和旧版本之间有很大的区别，因为它遵循 .NET Visual Studio 风格并集中了用户界面外观，再加上它的 Web 版本并使用 XML、AJAX 等新的 Web 技术， C# 和.NET。
Sybase 似乎正在完全迁移到 Microsoft，也许有一天我们听说它被 Microsoft Corporation 出售并拥有。
那么，如何学习和掌握Sybase PowerBuilder .NET V12.0呢？
我应该了解哪些主要部分？有哪些免费网络资源、电子书、参考资料、网站和教程可以帮助我？
如何将我们拥有的旧版本迁移到这个新版本？
我将面临哪些困难以及我将获得哪些优势？
I am new in Sybase PowerBuilder and I noticed a big difference between it and old versions as it follows the .NET Visual Studio style and concentrates the user interface look, plus having the web version of it and using new web technologies like XML, AJAX, C# and .NET.
It seems that Sybase is on its way to migrate totally to Microsoft and maybe one day we hear it is sold and owned by Microsoft Corporation.
Anyhow, how I can learn and master Sybase PowerBuilder .NET V12.0?
What are the major parts I should know? What are the free web resources, e-books, references, web sites and tutorials that will help me?
How I can migrate the old versions we had to this new version?
What are the difficulties I will face and what are the advantages I will gain?

这是很多问题:)
PowerBuilder 12 是一个重要的版本，它附带的文档是完整且全面的。它也可以在线获取 - 也许一个好的起点是 新功能指南 或.NET 功能指南。
不幸的是，没有关于该主题的任何印刷书籍，但有一些网站提供了一些很好的资源：
我们发现即使对于非常大的应用程序，迁移也很简单。 WPF 窗口应用程序目标向导将引导您完成整个过程，之后需要修复应用程序的所有不兼容区域。其中涉及多少工作取决于您的应用程序。
之后，最好的方法是开始编码并探索可用的内容。
That's a lot of questions :)
PowerBuilder 12 is a big release and the documentation that ships with it is complete and comprehensive. It is also available online - perhaps a good place to start would be the New Features guide or the .NET features guide.
Unfortunately there aren't any printed books on the subject but there are a few websites with some good resources:
We found migrating to be straightforward, even with a very large application. The WPF Window Application target wizard will walk you through the process, after which it is a matter of fixing all the incompatible areas of your application. How much work is involved with that is dependent on your application.
After that your best approach is start coding and explore what is available.
首先转换为PowerBuilder 12 Classic（创建工作空间，创建目标），然后编译。修复编译器弹出的任何错误。这些错误是不正确的代码，不会影响旧版本。但是，它们将在此版本中弹出。我已经转换了两个大应用程序，但从未找到其他东西。
然后运行PowerBuilder.net自动迁移。将会出现更多错误。您需要修复它们，并且可能需要重新设计一些不受支持的功能。
First convert to PowerBuilder 12 Classic (create work space, create target), then compile it. Fix any bugs the compiler pops up. Those bugs are incorrect code which does not bother the older version. However, they will pop up in this version. I have converted two big apps and never find something else.
Then run PowerBuilder.net to migrate automatically. There will be more bugs which pop up. You need to fix them and you may need to rework some unsupported features.
