处理Silverlight onerror回调 [英] Handling Silverlight onerror callback

问题描述

Silverlight对象标签接受一个'onerror'参数，该参数调用您选择的一个javascript。 Visual Studio模板生成的默认实现组合了一个描述性的消息，并将其作为一个错误（即IE显示小警告三角形）将其抛出。

The silverlight object tag accept an 'onerror' parameter which calls back to a piece of javascript of your choice. The default implementation which is generated by the Visual Studio template assembles a descriptive message and throw it as an Error (which lets e.g. IE display the little warning triangle).

对我来说，每次这个回调被触发，我们的silverlight实例都已经死了，你需要刷新页面。这是一个合理的扣除吗？

It seems to me that each time this callback is fired our silverlight instance is dead and you need to refresh the page. Is this a reasonable deduction?

另一个问题是如何最好地处理这个回调。显示小警告图标有点以开发人员为中心，它不允许我们（开发人员）在客户机上运行时发现生产中实际失败的情况。人们在做什么？几个我们自己的（或多或少具体）的想法是：

Another issue is how to best handle this callback. Showing the little warning icon is somewhat developer-centric and it doesn't allow us (the developers) to discover what is actually failing in production when it is run on a customer machine. What are people doing with this? A couple of our own (more or less concrete) ideas are:

• 通过一些暴露的错误信息发送回服务器端点

• Send the error message back to the server via some exposed endpoint

删除隐藏silverlight对象，向用户显示更好和更具描述性的消息以及刷新链接，以再次启动silverlight页面运行一个全尺寸的silverlight应用程序，所以如果silverlight对象不工作，客户也可以重新加载）

Remove hide the silverlight object, show a nicer and more descriptive message to the user and a 'refresh' link to start up the silverlight page again (we run a full-sized silverlight application so if the silverlight object isn't working, the customer might as well reload anyway)

想法，想法，最佳做法，反模式？你们做什么（除了确保silverlight应用程序永远不会失败，但这是另一个讨论）？

Ideas, thoughts, best practices, anti-patterns? What are you guys doing (except ensuring that the silverlight app never fails, but that's another discussion)?

推荐答案

我喜欢一个很好的使用SilverlightFX的表单形式的错误报告来源 http://github.com / NikhilK / silverlightfx / tree / master ，检查出来非常酷的框架，否则基本上只是一个错误的总结，通过上传发送电子邮件支持的能力和哎呀我们goofed标题： ）我以这种方式处理所有未处理的expetions，还有一篇很好的文章，通过类型使用字典处理错误
http://www.netfxharmonics.com/2009/04/Exception-Handlers-for-Silverlight-20 也是我的最爱我的
。希望这有助于

I like a nice error reporting in the form of a "form" using SilverlightFX grab the source http://github.com/NikhilK/silverlightfx/tree/master , check it out very cool framework otherwise basically would be just a summary of the error, the ability to send it via upload that emails to support and an "oops we goofed" title :) I handle all unhandled expetions in this way, there is also a nice article on handling the errors by type using a dictionary http://www.netfxharmonics.com/2009/04/Exception-Handlers-for-Silverlight-20 also a favorite of mine . Hope this helps
