使用Wisej将Windows桌面应用程序迁移到Web
Moving Windows Forms, WPF, VB6 or other legacy applications to the web can be hard and expensive. The migration roadblocks can be endless when evaluating current web technologies. If you’re the new guy tasked with rewriting the entire application in Angular or another web technology... good luck!
将Windows Forms，WPF，VB6或其他旧版应用程序移动到Web上可能既困难又昂贵。 在评估当前的Web技术时，迁移的障碍可能是无止境的。 如果您是负责用Angular或其他Web技术重写整个应用程序的新手，祝您好运！

案例研究：业务线应用程序面临的挑战 (Case Study: Challenges with Line-of-Business Applications)
Today’s world of enterprise-scale business applications usually shows a feature-rich history of evolvement and enhancements, making the transition from Windows desktop to native web a difficult, risky, and sometimes unrealistic task. What are typical challenges and how does it work?
当今的企业级业务应用程序世界通常显示了功能丰富的演进和增强历史，这使得从Windows桌面到本地Web的转换变得困难，危险，有时甚至不切实际。 典型的挑战是什么，它如何运作？
Let’s take a brief look at an example from the public sector:
让我们简单看一下公共部门的一个例子：
Harris Local Government (part of the Constellation Software Group) decided to modernize 150 separate Windows modules developed in Visual Basic 6 to an integrated web-based platform. Harris serves more than 5,500 small and mid-sized municipalities with a wide variety of solutions such as vehicle registration, real estate, personal property, and utility billing. The software suite includes financial modules such as accounting, fixed assets, and payroll.
哈里斯地方政府(星座软件集团的一部分)决定将Visual Basic 6中开发的150个单独的Windows模块现代化为一个基于Web的集成平台。 哈里斯(Harris)为5500多个中小型城市提供服务，并提供多种解决方案，例如车辆登记，房地产，个人财产和公用事业计费。 该软件套件包括财务模块，例如会计，固定资产和工资单。

Developing a complex enterprise-scale application from scratch is usually not an option that works. Here are typical obstacles to take into consideration:
从头开始开发复杂的企业级应用程序通常不是可行的选择。 以下是需要考虑的典型障碍：
- Time, effort, risk and cost of a manual rewrite are in many cases beyond consideration. An application with hundreds or thousands of forms and dialogs may take dozens of man/years to rewrite and test from scratch. 在许多情况下，手动重写的时间，精力，风险和成本是无法考虑的。 具有数百或数千种表单和对话框的应用程序可能需要数十个人/年才能从头开始重写和测试。
- There is a huge risk when doing a manual rewrite without the ability to take over busin
