What do people call their factory functions? 'new' is not an option
(yes, it can be overloaded but has to return void*).
The context is:
class MyClass
{
public:
// Factory functions
static MyClass* new(int);

Hi,
Sorry if this was previously discussed but it's something I miss in
Python. I get around this using isinstance() but it would be cleaner
to have separate functions with the same name but different argument
types. I think the idea gets quite close to the Lisp/CLOS
implementation of methods.
Below is just simple implementation example (and class functions are
not supported) but it can be further extended/optimised/modified for

So, I got the itch to write something more...
I apologize for not doing more on the attempted "Correct C++ Tutorial"
earlier, but there were reasons.
This is an UNFINISHED and RAW document, and at the end there is even pure
mindstorming text left in, but already I think it can be very useful.

I just wanted to throw this up here in case anyone smarter than me has
a suggestion/workaround:
Problem:
I have a classic producer/consumer system which accepts 'commands' from
a socket and 'executes' them. Obviously, each different command (there
are ~20 currently) has its own needed functionality. The dream goal
here would be to remove all knowledge of the nature of the command at
runtime. That is, I don't want ANY switch/cases...

I'm relatively new to C# and polymorphism, so what I'm trying to accomplish
may not be possible, or there may be a totally different approach that I
should be taking.
I have a base class (MyBase) and a collection of MyBase objects
(MyBaseCollection). Now, I also have an extension to MyBase (MyExtendedBase
: MyBase) that has additional properties. And lastly, I have a collection
of MyExtendedBase objects(MyExtendedBaseCollection :...

I have to write a paper about object oriented programming and I'm doing
some reading to make sure I understand it. In a book I'm reading,
however, polymorphism is defined as:
"the ability of two different objects to respond to the same request
message in their own unique way"
I thought that it was:

Hello,
I have a set of DLLs that implement different configurations of the
same API. Consider them as first.dll, second.dll, and third.dll. They
all share a common API, calling pattern, and have the same logic to
handle the calls. Calls in the VB.net code does not call the DLLs
directly, but rather a custom dll wrapper class, so that the logic can
be made for the VB code in the abstraction class.
Initially, my idea was to create a...

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.
First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

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,...

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. I'm particularly interested in Zigbee because I've heard it does some...

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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
