My goal here is to get stack trace information from a dynamically loaded assembly. If the dynamically loaded assembly just throws the error back to the caller, the stack trace information doesn’t tell you the location in the dynamic assembly where the error occurred. If I throw my own exception, passing in the original exception, it wil...
I'm running some code through FxCop and am currently looking at clearing all of the non-breaking violations. The code itself has a few instances of try/catch blocks which just catch general exceptions; try { // Some code in here that could throw an exception } catch(Exception ex) { // Exception Thrown ... sort it out! } Now...
In my Java code, I have a function called getAngle() which sometimes throws a NoAngleException. Is the following code the best way of writing a function that keeps calling getAngle() until no exception is thrown? public int getAngleBlocking() { while(true) { int angle; try { angle = getAngle(); return ...
In the upcoming scala 2.8, a util.control package has been added which includes a break library and a construct for handling exceptions so that code which looks like: type NFE = NumberFormatException val arg = "1" val maybeInt = try { Some(arg.toInt) } catch { case e: NFE => None } Can be replaced with code like: import util.control....

What is the scope of the exception object in C++? does it go out of scope as soon as catch handler is executed? Also, if I create an unnamed exception object and throw it, then while catching that exception does it matter if I catch it by const reference or a non-const reference? ...

Hi, I have the following issue and I would like to know what exactly happens. I am using Java's ScheduledExecutorService to run a task every five minutes. It works very well. Executors completely changed the way I do thread programming in Java. Now, I browsed Java Doc for information about what would be the behavior in case the schedul...
I am working on a client-server application. The client continuously reads data from server, so when a server is closed or disconnects then the client crashes. I tried a try/catch block, but it didn't work. My client application is written in C++. I want the client to display some proper message like "Server disconnected," then exit. ...

We have an interface IPoller for which we have various implementations. We have a process that will take an IPoller and start it in a separate thread. I'm trying to come up with a generic way of providing exception handling for any IPollers which don't do it themselves. My original thinking was to create an implementation of IPoller t...
This is my BMI calculator with GUI. It compiles, but if the user enters characters rather than numbers into the fields, the program crashes. What is wrong with my catching of the numberformatexception? Id appreciate any help! import java.awt.*; import javax.swing.*; import java.awt.event.*; class Exercise1b extends JFrame{ JLabel BMIl...
I've seen at least one reliable source (a C++ class I took) recommend that application-specific exception classes in C++ should inherit from std::exception. I'm not clear on the benefits of this approach. In C# the reasons for inheriting from ApplicationException are clear: you get a handful of useful methods, properties and constructor...
The title really is the question for this one: Is there an equivalent in T-SQL to C#'s "throw;" to re-throw exceptions? In C# one can do this: try { DoSomethingThatMightThrowAnException(); } catch (Exception ex) { // Do something with the exception throw; // Re-throw it as-is. } Is there something in T-SQL's BEGIN CATCH f...

I have two modules, main and notmain. I declared my custom exception in main module and want to catch it. This exception is raised in notmain module. The problem is I can't catch my exception raised in notmain module. main.py: class MyException(Exception): pass m = __import__('notmain') try: m.func() except MyException as e: ...
I have a few questions relating to setjmp/longjmp usage - What is the use of setjmp(jmp___buf stackVariables) returning 0. It is a default, which we cannot influence. Is the only significance of setjmp(stackVariables) is to push the stack in stackVariables. And basically 0 tells us if the stack was pushed on stack_variables success...
