Global Exception Handling for winforms control
提问by Alex
When working on ASP.NET 1.1 projects I always used the Global.asax to catch all errors. I'm looking for a similar way to catch all exceptions in a Windows Forms user control, which ends up being a hosted IE control. What is the proper way to go about doing something like this?
在处理 ASP.NET 1.1 项目时，我总是使用 Global.asax 来捕获所有错误。我正在寻找一种类似的方法来捕获 Windows 窗体用户控件中的所有异常，该控件最终成为托管的 IE 控件。做这样的事情的正确方法是什么？

You need to handle the System.Windows.Forms.Application.ThreadExceptionevent for Windows Forms. This article really helped me: http://bytes.com/forum/thread236199.html.

Currently in my winforms app I have handlers for Application.ThreadException, as above, but also AppDomain.CurrentDomain.UnhandledException
目前在我的 winforms 应用程序中Application.ThreadException，我有处理程序，如上所述，但也有AppDomain.CurrentDomain.UnhandledException
Most exceptions arrive via the ThreadExceptionhandler, but the AppDomain one has also caught a few in my experience
大多数异常是通过ThreadException处理程序到达的，但根据我的经验，AppDomain 也捕获了一些异常

If you're using VB.NET, you can tap into the very convenient ApplicationEvents.vb. This file comes for free with a VB.NET WinForms project and contains a method for handling unhandled exceptions.
如果您使用的是 VB.NET，您可以使用非常方便的 ApplicationEvents.vb。该文件随 VB.NET WinForms 项目免费提供，并包含处理未处理异常的方法。
To get to this nifty file, it's "Project Properties >> Application >> Application Events"
要获得这个漂亮的文件，它是“项目属性 >> 应用程序 >> 应用程序事件”
If you're not using VB.NET, then yeah, it's handling Application.ThreadException.
如果您没有使用 VB.NET，那么是的，它正在处理Application.ThreadException。
