For no apparent reason, a NullReference exception is thrown in
system.dll
(System.Net.Sockets.OverlappedAsyncResult.CompletionPortCallback).
Since I only get a disassembly from Visual Studio, it is almost
impossible to figure out what causes this. I've tried adding:
AppDomain.CurrentDomain.UnhandledException += new
UnhandledExceptionEventHandler (SystemErrorHandler);
to my main method, and a handler function:

Hi,
Is it possible for exception object to be aware of it's throwing?
I want to log in the text file when exeption is thrown, not when the
exception object is created (because I can create exception object that
is never thrown).
Thank you,
Nenad

I am wondering if there are some best practices for determining a strategy
for using try/catch blocks within an application.
My current thoughts are:
1. The code the initiates any high-level user tasks should always be
included in a try/catch block that actually handles any exceptions that
occur (log the exception, display a message box, etc.).
2. Low-level operations that are used to carry out the high level tasks

Hi,
While debugging my application when an explicit exception is thrown by me
(or an implicit exception is thrown internally) which is not handled
anywhere in the stack,
the execution breaks as expected but I can not continue.
I try start the execution and go back to running mode, but it always comes
to the same line
where the exception is first thrown.

Hello Group,
I am running an operation in a different thread. There are resources that
are released when the thread is done running. This is done at the end of the
execution as it raises an event, and then the operation handling this event
calls threaded object's dispose method.
The problem is: If an exception is thrown the event is never raised, the
operation never executes dispose and my resources get stuck on the memory
until the app...

If you bind a control, say a textbox, to a class.property, and in
changing the value of the textbox an error is thrown in the
class.property, you get stuck in the textbox and cannot leave:
Public Class XClass
Private myName as String
Public Property Name as String

I have created a Windows service which performs various functions
including setting variables in other application objects.
When the service runs under Local System account the functionality all
works OK, however when service runs under a user account it produces
exception errors when trying to set variables in the application
objects.
I created a .exe test harness which does the same and works OK when
run by the same user.

The simplicity of stack unraveling of C++ is not without defective

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
