Hello, I'm wondering what's the preferred way to manage exceptions in an MVP implemented with a Passive View. There's a discussion in my company about putting try/catch blocks in the presenter or only in the view. In my opinion the logical top level caller is the presenter (even if the actual one is the view). Moreover I can test the...

I spot some interesting articles about exception handle in CodeProject http://www.codeproject.com/KB/cpp/seexception.aspx After reading, I decided to do some experiment. The first time I try to execute the following code char *p; p[0] = 0; The program died without question. But After several times when I executed the same proble...
Hi, I'm using the .NET Exception Management Application Block (EMAB). As part of this I am implementing IExceptionPublisher classes. However, I am wondering what happens if these publishers encounter an Exception. I had a bit of a look around and apparently they are meant to do something like this: try { /* Normal Exception Pub...
Basically I want to take the following: And make it match the styling of the rest of the application. I am creating a custom error page in my C# based project and I want it to be able to show the same information that is displayed in the ASP.NET default error page. From fiddling with reflector I can see that this is generated through ...
Do any languages that support retry constructs in exception handling track and expose the number of times their catch/rescue (and/or try/begin) blocks have been executed in a particular run? I find myself counting (and limiting) the number of times a code block is re-executed after an exception often enough that this would be a handy la...
Sometimes in .NET (2.0) WinForm desktop apps which use the default configuration system, the user.config file will become corrupted and can't be loaded anymore (when the configuration system tries to load it, it'll throw a System.Xml.XmlException). Putting aside the question of "why did the file get corrupted in the first place" (maybe ...
After some digging into exception handling in silverlight and reading some useful blogs like this Silverlight exception handling using WCF RIA Services and WCF Services I ended up implementing similar idea in the App.xaml.cs to show an error page and call another wcf service method to log the error to the event viewer: private void A...
Consider this pair of Throwable: IllegalAccessExceptionextends Exception Thrown when an application tries to reflectively create an instance (other than an array), set or get a field, or invoke a method, but the currently executing method does not have access to the definition of the specified class, field, method or constructor...
Anyone know how register an event handler for unhandled exceptions in C# .NETMF 4.0? A Google search reveals nothing. Thanks! ...
I'm wondering why .NET exceptions classes from Base Class Library has some mutable members by default Why I can change the Source, HelpLink and values from Data, but can't change anything else like the Message? Why throwing the exception rewrites the StackTrace making it mutable too? Is appending the stack trace information to existing...
I have a method which allocates an object and then releases it at the end. In between, the method calls another method which could possibly raise an exception, and the exception will probably be caught by the method calling my method. If this happens, the object will never get released (or will it?). How should I prevent this from happen...
Is there any section in c++ for which we can not handle exceptions? ...
Hi, Is there any way I could catch any uncaught exception in javascript? I mean, all my "dangerous" code are in try-catch blocks. But what about exceptions that I don't handle explicitly? I'm using jQuery, my main javascript file starts with : $(document).ready(function(){}) here I bind some events to some DOM elements. I can use t...

Hi, In .NET, when catching exceptions, should I always catch derived exceptions (so not ArgumentException but the derived types)? Also: If I am asked to use error codes, would this be in the constructor like so?: throw new Exception("4000", ex); Or a custom exception type with an errorcode property? (This may get confusing with exce...
I'm implementing an ActivityStream for my site based on the answer provided in this question: http://stackoverflow.com/questions/202198/whats-the-best-manner-of-implementing-a-social-activity-stream. My approach is to use observers after_create to create the activity record, including the metadata. I have a ton of observers, and don't ...

In advance, please excuse my lack of understanding for iPhone/Objective-C Best Practices; I come from a .NET/C# background. Although, I've read many posts regarding exception handling for the iPhone, I'm still not exactly clear on what most people do for production code. Also, I haven't been able to find any open source apps with error ...
