Take a look at this code, it looks funny as its written to be as short as
possible:
-- code --
struct Base
{
~Base() { *((char*)0) = 0; }
};
struct Derived : public Base

Hi there,
I'm reffering to a text that says following:
"To summarize: When a copy of an object is generated because it passed
to a function, the object's constructor function is not called.
However, when the copy of the object inside the function is destroyed,
its destructor is called.
By default, when a copy of an object is made, a bitwise copy occurs.

Which is a more correct statement?
A destructor runs automatically when an object is deallocated.
or
A destructor runs automatically immediately before an object is
deallocated.

I am looking for the quintessential blueprint for how a
C++ like destructor should be implemented in C#. I see
all kinds of articles in print and on the web, but I see
lots of discrepencies. For example ...
C# Essentials (O'Reilly) - "Finalizers are class-only
methods". Not sure what "class-only method" means in this
context, but ususally I would assume that to mean it is
static and would only be called once for the life of the...

I have an application that creates a class. The class has unmanaged
resources, so must end gracefully.
How can I guarantee that the unmanaged resources are freed?
I have looked at IDisposable, but this seems to rely on a call from the
application, e.g.
MyClass.Dispose()

Hi,
I have written an ActiveX object to resize images and upload them to a
database, this all works fine but when I close internet explorer the
process iexporer.exe is still running in my task manager and I can not
launch anything from the desktop (eg. a web shortcut) without firt
killing this process. The object is launched using JScript with the
following code:
var Launcher = new ActiveXObject("LaunchControl");

This may sound very elementary, but can you trap when your object is
set to null within the object?
I have created a class that registers an event from an object passed
in the constructor. When my object is destroyed, I want my object to
un-register this event. If I don't then the object would never be
destroyed until the object I passed in the constructor is destroyed.
I have implemented a Dispose(), Dispose(bool), and ~Finalize...

I have made a simple text example. I have two projects. First is an
unmanaged static lib, containing function F(), which created an object
of type A and throws an exception. The second project is a C++/ME
console application that calls F() and catches all exceptions with a
"catch(...)" filter. The thing that I dont understand is why doesn't
the auto object created on stack get destroyed. See my sources:
Project 1. Unmanaged lib....

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,...

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...
