Hello good people, I was using a foreach loop to go through a list of data to process (removing said data once processed--this was inside a lock). This method caused an ArgumentException now and then. Catching it would have been expensive so I tried tracking down the issue but I couldn't figure it out. I have since switched to a for l...

Why would a dependency-property implementation crash my application when I provide a default value? This segment of code is in the class declaration for my UserControl object. Everything works fine - it compiles and runs perfectly. public static System.Windows.DependencyProperty DepProp = System.Windows.DependencyProperty.Regis...
I'm writing a (C++) application that utilizes a single dialog box. After setting up a message pump and handler I started wondering how I would go about propagating C++ exceptions to my original code (i.e., the code that calls CreateDialogParam, for instance). Here's a skeleton example of what I mean: BOOL CALLBACK DialogProc(HWND, UINT...

So I'm given this code and I have to create an Exception and then use a Try Catch Block to catch it. I've already made the Exception, at the bottom of the code. But I've never used a Try Catch Block before and am not sure how to implement it. The Exception is if a rank that isn't listed under the enum is entered. I need to use a toStri...

I have seen several questions about exiting a script after a task is successfully completed, but is there a way to do the same for a script which has failed? I am writing a testing script which just checks that a camera is functioning correctly. If the first test fails it is more than likely that the following tests will also fail; there...
If an exception propagates all the way up to the top of my application (which, of course, will never happen), I would like to offer the option of sending an error report to me before the program crashes. What I have in mind is wrapping everything in the Main function in a try-catch, and a little class that sends the stack trace and other...

I have a very simple Windows application, with a few controls, a DataGridView and the Adobe PDF viewer control. The app works fine except when tabbing around to switch focus between controls, I regularly get the following exception. System.AccessViolationException was unhandled Message="Attempted to read or write protected memory. Thi...
I know the exception is kind of pointless, but I was trying to learn how to use / create exceptions so I used this. The only problem is for some reason my error message generated by my exception is printing to console twice. import java.io.File; import java.io.FileNotFoundException; import java.io.PrintStream; import java.util.Scanner; ...

I would like to write a function in Python (2.6) that can determine if it is being called from exception handling code somewhere up the stack. This is for a specialized logging use. In python's logging module, the caller has to explicitly specify that exception information should be logged (either by calling logger.exception() or by usi...
Hi I have a VxWorks application running on ARM uC. First let me summarize the application; Application consists of a 3rd party stack and a gateway application. We have implemented an operating system abstraction layer to support OS in-dependency. The underlying stack has its own memory management&control facility which holds memory ...
In C++ (MSVC) how can I test whether an exception is currently "in flight". Ie, code which is being called as part of a class destructor may be getting invoked because an exception is unwinding the stack.. How can I detect this case as opposed to the normal case of a destructor being called due to a normal return? ...
