Reporting an error from a POST Web Service
I'm developing a web service (in asp.net) and I would like to have each web method report to whoever called it when an internal error occurs - for example when input validation has failed. When I expose my web service with SOAP such errors can be reported by raising a SoapException. But what if I expose my web service with plain POST (...
Exception that goes away with Clean/Rebuild. How to diagnose/prevent?
Pre-Problem: our office was hit by a worm due to a corporate patching oversight, and the boys in the lab repaved my machine. I needed to re-install all my development tools (Visual Studio 2005, SP1, and the Web Application Project Setup patch) again. The following problem did not occur before this event. I've been working on an ASP.NET ...
Exception line numbers are messed-up on CCNET build reports
We are having an integration server (CruiseControl.NET) building and validating a couple of .NET 3.5 libraries. When some integration code fails, the exception is logged and appears in a custom report. Yet, the line numbers reported by the exception messages are messed-up - usually short from 50 / 100 lines below the place where the exc...

Should I add throw() to the declarations for my C++ destructors?
I have seen some C++ classes with a destructor defined as follows: class someClass { public: someClass(); ~someClass() throw(); }; Is this a good idea? I am well aware that destructors should never throw exceptions, but will this actually prevent me from throwing exceptions in my destructors? I'm not 100% sure wha...
C++: Error handling problem across threads
In general I use exceptions to deal with errors, however the problem I have here is that the error applies to a different thread than the one that caused it. Basicly the window has its own thread, and the direct3d device must be created and reset by the same thread that created the window. However creating the device may fail, so I need...
In Java how would you write the equivalent of Iterable which could throw exceptions?
In java a class can implement Iterable which lets you use the foreach() statement and the iteration syntatic sugar: for(T t:ts) ... However, this does not allow you to throw exceptions on the construction for an Iterator. If you were iterating off a network, file, database etc it would be nice to be able to throw exceptions. Obvious ...
How lean do my C++ exception classes really need to be?
There are lots of places where guidelines for designing exception classes can be found. Almost everywhere I look, there's this list of things exception objects should never do, which impacts the design of those classes. For instance, the Boost people recommend that the class contain no std::string members, because their constructor coul...

wxPython is not throwing exceptions when it should, instead giving raw error messages
I'm coding the menu for an application I'm writing in python, using wxPython libraries for the user interface, and I'm attempting to add icons to some of the menu items. Because I'm trying to be conscientious about it, I'm trying to limit the damage done if one of the image files referenced doesn't exist, and the most simple method (in ...
A recursive way to display Exception Messages in ASP.NET
Hello, I have started to make heavy use of exceptions, I'm sure I'll grow out of it as a learn the advantages and disadvantages the hard way, but until I've become an exception guru I'd like to know if this technique is acceptable. I intend to wrap, say a database exception in my own 'SorryFailedToSaveYourData' exception and then recur...
Is that a good idea to define exception with template?
Hi, I am thinking is that a good idea to define exception with template. Defining different types of exception is a super verbose task. You have to inherit exception, there is nothing changed, just inherit. Like this.. class FooException : public BaseException { public: ... }; class BarException : public BaseException { public: ...
Exception other than RuntimeException
Is there any possibility of exceptions to occur other than RuntimeException in Java? Thanks. ...
ArgumentNullException or NullReferenceException from extension method?
What would you consider to be the best exception type to throw when an extension method is called on a null instance (where the extension method does not allow it)? Since extension methods are nothing but static methods you could argue that it should be ArgumentNullException, but on the other hand they're used like instance methods so it...
