How to: Display Safe Error Messages Other Versions Visual Studio 2010 .NET how to display error message in asp net using c# Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 When your application displays error messages, it should not give away information that a malicious user might find helpful in attacking your system. For example, if your application unsuccessfully tries to log in to a database, it should not display an error message that includes the user name it is using. There are a number of ways to control error messages, including the following: Configure the application not to show verbose error messages to remote users. (Remote users are those who request pages while not working on the Web server computer.) You can optionally redirect errors to an application page. Include error handling whenever practical and construct your own error messages. In your error handler, you can test to see whether the user is local and react accordingly. Create a global error handler at the page or application level that catches all unhandled exceptions and routes them to a generic error pag

ASP.NET web-site, and would like the ability to conditionally show/hide runtime error messages depending on who the user visiting the site is.For a normal user visiting the site you want to be able http://weblogs.asp.net/scottgu/Tip_2F00_Trick_3A00_-Show-Detailed-Error-Messages-to-Developers to display a friendly error message like this when a runtime error occurs: But when someone within the “developers” security role of your application remotely accesses the site you want to instead show a more detailed exception stack trace error message about the problem without having to change any configuration data: The below post describes how to use ASP.NET’s role-based security architecture in conjunction with the asp net Global.asax Application_Error event handlerto enable this. You can also download a sample I’ve built that shows how to implement this here.Some Background Discussion on Error Handling and ASP.NET Custom Error Pages:ASP.NET and .NET support a rich error-handling architecture that provides a flexible way to catch/handle errors at multiple levels within an application. Specifically, you can catch and handle a runtime exception with a class, within a page, asp net error or on the global application level using the Application_Error event handler within the Global.asax class. If a runtime exception isn’t handled/cancelled by one of these mechanisms, then ASP.NET’s Custom Error Page feature will kick-in, and an error page will be sent back to the browser accessing the application.ASP.NET’s Custom Error Page feature can be used to configure a “friendly error page” to be displayed to end-users in place of the standard “server error occurred” message sent back by ASP.NET. For example, the below web.config file section will cause remote users visiting the site to be redirected to a “friendlyErrorPage.htm” file anytime a runtime error occurs (note: HTTP 500 status code responses indicate runtime errors on the server):
