Visual Basic Concepts Visual Studio 6.0 Centralized Error Handling When you add error-handling code to your applications, you'll quickly discover that you're handling the same errors over and over. With careful planning, you can reduce code size by writing a few procedures that your error-handling code can call to handle common error situations. The following FileErrors function procedure shows a message appropriate to the error that occurred and, where possible, allows the user to choose a button to specify what action the program should take next. It then returns code to the procedure that called it. The value of the code indicates which action the program should take. Note that user-defined constants such as MnErrDeviceUnavailable must be defined somewhere (either globally, or at the module level of the module containing the procedure, or within the procedure itself). The constant vbExclamation is defined in the Visual Basic (VB) object library, and therefore does not need to be declared. Function FileErrors () As Integer Dim intMsgType As Integer, strMsg As String Dim intResponse As Integer ' Return Value Meaning ' 0 Resume ' 1 Resume Next ' 2 Unrecoverable error ' 3 Unrecognized error intMsgType = vbExclamation Sele

million programmers, just like you, helping each other. Join them; it only takes a minute: Sign up Java Error handling - is it better to throw Exceptions to centralized error handlers? up vote 3 down vote favorite https://msdn.microsoft.com/en-us/library/aa240795(v=vs.60).aspx I've got a decently complex little game going on in Java (solitaire, essentially like the Windows version), but I have yet to do very much error handling. Almost all of the methods across my classes will end up either getting called by an initial constructor (eventually main()), a paintComponent() method, or a mouse event. So, my question is, is it bad practice to just use "throws Exception" on all of my lower-level methods, http://stackoverflow.com/questions/10179266/java-error-handling-is-it-better-to-throw-exceptions-to-centralized-error-hand and only do a try/catch at my top-level methods to catch ALL the errors at once? (e.g. 3 try/catches - one for the painting, one for mouse events, one for the main method). I realize this prevents me from easily dealing with errors on-the-spot, but I don't really plan on doing that anyways. My error handling is going to consist of writing to a log, telling the user, and killing the program. Keeping this in mind, is there anything bad with doing my error handling this way? java error-handling share|improve this question asked Apr 16 '12 at 18:04 user891876 133112 1 No. That seems like an okay way to handle errors. –Hassan Apr 16 '12 at 18:09 Related to stackoverflow.com/questions/5284699/… –fgb Apr 16 '12 at 19:13 add a comment| 5 Answers 5 active oldest votes up vote 1 down vote accepted It depends on how you want to approach the situation. If you just want to catch any possible exception and you don't mind about the handler code, you could simply use "throws exception", and there's nothing BAD with it either. It's like a try-catch block that covers all the function. If you want to write specific code for specific exceptions, you should use try-catch blocks to write appropriate code for each handler. Based
cannot go wrong will go wrong as well”. Wise man that Murphy, but what does it mean for http://radek.io/2011/09/13/best-practices-in-error-handling/ us, the programmers out there in the trenches? Error handling and reporting is a programming nightmare. It’s an extra work, it pollutes happy path of your code with whole bunch of weird if statements and forces you to return sets of mysterious error codes from functions. God, I hate error reporting (more than I hate New Jersey). error handling It might not seem very important, but it’s crucial to set some error handling strategy and stick with it through the whole project. The error reporting code will be literally everywhere. If you choose poor strategy in the beginning, all of your code will be condemned to be ugly and inconsistent even before you start writing it. There node js error are multiple problems, that you need to address in error reporting. The most important thing is to deliver an useful report to the user. The error message should say what happened and why it happened. A stack trace can help you find exactly what happened, but it generally won’t make the user very happy. My personal favorite format of reporting errors in terminal apps looks like this:
