Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the asp.net error handling Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a request for a nonexistent .html or .jpg file does not cause a redirect to the Http404ErrorPage.aspx file. If you want ASP.NET to handle requests for all file types, you can configure IIS to map file-name extensions to ASP.NET. Note In the example, the mode attribute is set to "On" so that you can error messages when you run the example in Visual Studio. In a production environment, this setting would normally be "RemoteOnly". ASP.NET then renders error pages to external users. If a request is

Web Hosts XML Information: Advertise Feedback Author an Article Published: Wednesday, September 6, 2006 Gracefully Responding to Unhandled Exceptions - Displaying User-Friendly Error Pages By Scott Mitchell Introduction In .NET applications, an illegal operation - an invalid cast, attempting to reference a null value, trying to connect to a database that's been taken offline, and so on - raises an exception. Exceptions can be caught and handled directly in code through the use of Try / Catch blocks. For ASP.NET applications, if the exception is not handled in code, it bubbles up to the ASP.NET runtime, which raises an HttpUnhandledException. By default, unhandled exceptions result in a page that displays the text, "Runtime Error" with instructions for developers on how to display exception details (see the screen shot to the right). This "Runtime Error" error page is what is seen by external visitors; if you visit your site through localhost and an unhandled exception occurs, the default error page includes the type and details of the exception thrown. [View a screenshot] End users will no doubt find the "Runtime Error" page to be intimidating and confusing - do you think the average computer user knows what "Runtime" means? All the user knows is that something went horribly wrong. They might fear that their data or progress has been lost and that they are responsible for the error. Ironically, the person who does care that an unhandled exception has occurred - the developer - is left out of the loop unless the end user takes the time to email the developer the details of the error (what page it happened on, the steps the user had performed that caused the error, and so on). Fortunately, ASP.NET provides solutions to these two problems. An ASP.NET application can be configured to automatically redirect the user to a less-intimidating page that explains that there has been a problem. This custom, user-friendly error page can omit such lingo like "Runtime" and have its look and feel match the website's. Additionally, there are techniques available to log and alert the developer of the unhandled exception. In this article we'll look at how to display user-friendly error pages in the event of an unhandled exception. A future article (Processing Unhandled Exceptions) will examine how to log and alert the site administrator when such exceptions occur. Read on to learn more! -continued- Displaying a U
