# some_factory returns an instance of Base

I want to have a single instance of a base class that all the child classes
inherits from.
The base class is going load data from text files and this only needs to be
done once.
What I don't need is every time a child class is created that it goes out
and creates another instance of the base class, which then would go out and
load data from those text files.
Am I making sence here?
How can I do this in VB.Net?

Hello -
I have a Base Class where I want a New() implemented that can be called
from the outside. This New() should create an instance of the
appropriate cDerivedX Class ...
The following shows a scenario where it was determined that cDerivedA
is needed based on a configuration file.
Dim lInstance As New cBase()

I just ran across a case which seems like an odd exception to either
what I understand as the "normal" variable lookup scheme in an
instance/object heirarchy, or to the rules regarding variable usage
before creation. Check this out:
>>> class foo(object):
.... I = 1
.... def __init__(self):
.... print self.__dict__
.... self.I += 1

I've been scanning Python in a Nutshell, but this seems to be either
undoable or so subtle that I don't know how to do it.
I want to subclass a base class that is returned from a Standard Library
function (particularly, subclass file which is returned from open). I
would add some extra functionality and keep the base functions, too.
But I am stuck.

Hello All,
I have case where I create one instance of a class "Base" and there are various other child objects that I need to create ("Derived" from "Base"). Is there a pattern where I could ensure that once I create a base class instance in memory, all derived classes refer the same base instance ?
class Base{
//..functions etc
}

Hello everyone,
Thanks to many useful posts in this newsgroup and others, I've been
able to come very close to something I've been wanting to do for a
very long time.
I've figured out how to create a new custom protocol handler in
Windows to handle locations like "myProtocol:", which lets me have a
shortcut pointing to "myProtocol:myPrimaryKey" and have my application
automatically open and display the given account. That's great. I

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,...

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...

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...
