I have a windows service that runs various system monitoring operations. However, when running SNMP related checks, I always get a NullReference exception.

I've created a custom exception for a very specific problem that can go wrong. I receive data from another system, and I raise the exception if it bombs while trying to parse that data. In my custom exception, I added a field called "ResponseData", so I can track exactly what my code couldn't handle. In custom exceptions such as this on...
I've inherited a hoary old piece of code (by hoary, I mean warty with lots of undocumented bug fixes than WTF-y) and there's one part that's giving me a bit of trouble. Here's how it connects to the remote registry to get the add/remove programs key: try { remoteKey = RegistryKey.OpenRemoteBaseKey( ...

This is the day of weird behavior. We have a Win32 project made with Delphi 2007, which hosts the .NET runtime and calls into .NET to show new forms, as part of a transition period. Recently we've begun experiencing exceptions at seemingly random locations and points of our code: Arithmetic overflow or underflow. The stack trace of on...
I am calling, through reflection, a method which may cause an exception. How can I pass the exception to my caller without the wrapper reflection puts around it? I am rethrowing the InnerException, but this destroys the stack trace. Example code: public void test1() { // Throw an exception for testing purposes th...
I am getting the below error and call stack at the same time everyday after several hours of application use. Can anyone shed some light on what is happening?

I can't tell from the Python documentation whether the re.compile(x) function may throw an exception (assuming you pass in a string). I imagine there is something that could be considered an invalid regular expression. The larger question is, where do I go to find if a given Python library call may throw exception(s) and what those are? ...
The following bit of code catches the EOS Exception using (var reader = new BinaryReader(httpRequestBodyStream)) { try { while (true) { bodyByteList.Add(reader.ReadByte()); } } catch (EndOfStreamException) { } } So why do I still receive first-chance exceptions in my console? A first chance ex...

I was just working on fixing up exception handling in a .NET 2.0 app, and I stumbled onto some weird issue with Application.ThreadException. What I want is to be able to catch all exceptions from events behind GUI elements (e.g. button_Click, etc.). I then want to filter these exceptions on 'fatality', e.g. with some types of Exceptions...
