In programming, a development error is one that can be prevented. Such an error can occur in syntax or logic. Syntax errors, which are typographical mistakes or improper use of special characters, are handled by rigorous proofreading. Logic errors, also called bugs, occur when executed code does not produce the expected or desired result. Logic errors are best handled by meticulous program debugging. This can be an ongoing process that involves, in addition to the traditional debugging routine, beta testing prior to official release and customer feedback after official release. A run-time error takes place during the execution of a program, and usually happens because of adverse system parameters or inv

The aim is to detect http://searchsoftwarequality.techtarget.com/definition/error-handling and handle errors in JavaScript avoiding embarrassing mistakes and sometimes even blocking your web client. Prerequisites We assume that our readers have a good level of knowledge with the .NET platform and the ASP.NET and AJAX technologies. In addition, note that this tip is based on our example on the Framework.NET 3.5 with the Microsoft Visual Studio 2008 IDE. ASP.NET error management with the Global.asax file http://ccm.net/faq/5249-asp-net-error-handling The Global.asax file offers us the opportunity to centralize the management of errors by capturing any unhandled error in our web application. This latter example allows us to redirect our user to a personalized web page, that will handle the error based on its type. If for example we get an error in the click event of a button in ASP.NET: protected void btn_Click(object sender, EventArgs e) { throw new Exception("Exception générée pour test !"); } The exception is not handled in the method, but it can always be taken in the method "Application_Error" of the "Global.asax" file: protected void Application_Error(object sender, EventArgs e) { // Capture last error Exception exception = Server.GetLastError().GetBaseException(); try { // Load error in memory Context.Session["Excep"] = exception; // Redirect request this.Response.Redirect("~/PageDErreur.aspx"); } catch (Exception innerEx) { string errorMsg = "Une erreur s'est produite lors du traitement de l'exception : " + exception.Message + ". "; errorMsg += Environment.NewLine + innerEx.ToString(); } } Of course, we must always add to our management function: an error log and if necessary a case by case treatment depending on the type of exception thrown. Finally, we can redirect our user to a web page displaying

That is, for the most part, if there is an error in the handling in web program it is our own fault rather than some unforeseen user blunder such as entering letters into a price field or a URL which does not exist. These types of errors can never be exactly programmed around because it is impossible to handle every weird thing that a user might do. We can handle programmatic errors by simply writing error-free code, but we cannot assure that run-time errors will not break our program. Thus, run time errors are just as important to deal with as errors in your programming code. In fact, they are often more important since your users will not be able to find the bug and recompile the program like you will be able to do. At run time, it is too late to debug. In order to handle the exceptional cases in which the user enters data which would cause your program to crash, Java provides a hearty exception handling methodology to catch erroneous input, try several methods to deal with it, and in the worst case, gracefully exit the program. So ho does Java deal with exceptions in the program? Well specifically, when an error occurs, Java will encapsulate all the information about the error in a special error object. Thus, rather than choke on the error, the routine which generates the error will look for an event handler object which can deal with the unexpected problem. The event handler object will look at the error event object a
