unhandled-exception

问题 I am working on a C# project and want to make use of the UnhandledException event to catch any exceptions I may have missed in my project (hoping there won't be any but to be on the same side). I make quite a bit of software so I want to make a class library that all of my projects will make use of so I want to have one function that does all of the initialisation stuff of all my projects without me having to copy and paste the code into each project to do the same work. What I am wondering

问题 How is an ASP.NET application supposed to deal with unhandled exceptions which are occuring on a non-request background thread (due to bugs)? By default, such exceptions cause the process to terminate. This is unacceptable in the setting of an ASP.NET worker process because concurrently running requests are aborted unpredictably. It is also a performance problem. Exceptions on a request thread are not a problem because ASP.NET handles them (by showing an error page). The AppDomain

问题 What is the best way to handle an unhandled exception in a WPF application? 回答1: You can use DispatcherUnhandledException : XAML (App.xaml): <Application x:Class="App.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="wndMain.xaml" DispatcherUnhandledException="Application_DispatcherUnhandledException"> Code Behind (App.xaml.cs/vb: private void Application_DispatcherUnhandledException(object sender, System

问题 I am getting an unhandled error but not sure where it's coming from. My app has several http.request(options, callback).end() in different methods, with the callback's trapping "uncaughtException" and "error". I'd like to know which of my methods initiated this issue. Below is the error I get. It is random. Any ideas how to track this down? I was hoping for some global way of trapping unhandled errors. events.js:85 throw er; // Unhandled 'error' event ^ Error: read ECONNRESET at exports.

问题 I have a small WinForms app that utilizes a BackgroundWorker object to perform a long-running operation. The background operation throws occasional exceptions, typically when somebody has a file open that is being recreated. Regardless of whether the code is run from the IDE or not .NET pops up an error dialog informing the user that an Unhandled exception has occurred. Compiling the code using the Release configuration doesn't change this either. According to MSDN: If the operation raises an

问题 I'm getting an unhandled message exception for IOException. As you can see in the pasted code I've handled the IOException. The JDK for both eclipse & the project is Java 8 update 121 so I know catching multiple exceptions is supported. What am I doing wrong? try (InputStream inputStream = BatchMessageProperties.class.getClassLoader(). getResourceAsStream(propertiesFileName)) { load(inputStream); //need to make sure all properties are present & not null. validate(this); } catch (IOException |
