I am writing a class that includes several async methods following the
BeginXxx, EndXxx pattern. Some of these methods will call methods in the
framework such as Stream.Read or Socket.Send. Do I need to, or is it
recommended to use the async method calls instead (Stream.BeginRead, etc)?
Example:
MyMethod()

Hi all,
The following (test) program is not working as I expected.
Note: The code is a bit long but is easy to understand: There is a
class Object implementing ref counting. A Ref<T> template (with a full
Ref<Object> specialization) that works like a smart pointer to the
Object-rooted hierarchy. The only way to create Object instances is
via a static factory that returns a Ref<Object> to a heap allocated
object.

Hi
I want to refer a class called LogEvent, and use one of its methods called
WriteMessage without actually having to create an instance of Logevent.
I have tried using the word sealed with the class and this works but I would
also like to know of other ways to do this.
Also are there any performance implacations of using sealed?

I have an abstract class, and a set of classes that inherit from my abstract
class. The fact that it is abstract is likely irrelevant. I have a static
factory method in my abstract class that creates subclasses. The
constructor in my subclasses must be able to call the constructor in my base
class. For the factory method in my abstract class to call the constructor
on my subclasses, the constructor in the subclass MUST be public (or...

Is it possible to call a method from a parent object, but have the
childs overriden method called instead of the base method?
I want several children objects to all call a certain method when they
are initialized, but they all have different implementations of that
method.
thanks

In his book "More Effective C++", Scott Meyer suggests in "Item 4" to
"Avoid gratuitous default constructors".
To summarize his claims against default constructors for "the right
classes" he states that:
================== START QUOTE =============
"A default constructor is the C++ way of saying you can get something
for nothing. Constructors initialize objects, so default constructors
initialize objects without any information from...

I have the following business entity classes shown below. I have a data
layer that
retrieves the data from the database and populates a new instance of
the PendingRecord class then adds it to the PendingRecords collection.
i.e. PendingRecords pendingRecords = dataLayer.GetPendingRecords();
What I would like to do is to be able to have a method in the
collection
class that I could pass a wizardId and get the specific PendingRecord

Hi Everyone,
This Saturday the stage was set. The problem simply could not go on
existing -- it had to be solved. Many hours, articles, compilations
and frustrations later I still did not find an answer. Even pacing
around my flat until I nearly went into an altered state of reality
proved futile.
So here is the problem...

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
