问题 Hey, I'm writing a network application, in which I read packets of some custom binary format. And I'm starting a background thread to wait for incoming data. The problem is, that the compiler doesn't let me to put any code throwing (checked) exceptions into run() . It says: run() in (...).Listener cannot implement run() in java.lang.Runnable; overridden method does not throw java.io.IOException I want the exception to kill the thread, and let it be caught somewhere in the parent thread.

Using ThreadExceptionEventHandler: determine which thread caused the exception

由 情到浓时终转凉″ 提交于 2019-12-24 03:07:24
问题 Using the Application.ThreadExceptionEventHandler, is it possible to determine which thread caused the exception (the thread id)? The same question applies to using the AppDomain.UnhandledExceptionEventHandler to catch non-UI thread exceptions. If the answer is no, is there any other way to determine which thread raised the unhandled exception in such cases? 回答1: I haven't checked, but I'd expect the handler to be executed in the thread which threw the exception - in which case Thread

Why do AppDomain exceptions invariably terminate the application?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-20 15:22:36
问题 This is related to a previous question. What I'm trying to understand now is how come UI thread exceptions can be prevented from terminating the application while non-UI exceptions can't be. For reference, see this example. Most importantly, what I would like to be able to do in that case is "silently" terminate the process--without displaying the Windows dialog box that asks whether I'd like to send an error report or not. This is my AppDomain UnhandledExceptionHandler: private static void

问题 I was trying to change the logging format by adding a context filter. My Format is like this FORMAT = "%(asctime)s %(VAL)s %(message)s" This is the class I use to set the VAL in the format. class TEST: def __init__(self, val): self.test_var=threading.local() self.test_var.value=val def filter(self,record): record.VAL=self.test_var.value return True def setValue(self,val) self.test_var.value=CMDID It works fine in a single threaded environment, but for a certain multi-threaded environment I

I'm completely stuck . I'm testing MetaTrader API and getting next error when tries to run a method in the Immediate Window of VS 2010: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll A first chance exception of type 'System.Threading.ThreadAbortException' occurred in System.Runtime.Remoting.dll Evaluation requires a thread to run temporarily. Use the Watch window to perform the evaluation. What does it mean? Can it happens because of runtime versions difference (api 2.0, app 4.0)? I believe the method you are calling through the Immediate
