The Top Level Design:
The class Base is a factory class with a twist. It uses the Assembly/Type
classes to extract all types that inherit from it and add them to the list
of types that inherit from it. During run time, using a static method, the
class creates an instance of the derived class using the Activator class and
returns it. This design pattern is very similar to the design pattern
applied by the Assembly class.
The twist is...

Hello Experts!
Some information.
In a more general form is the handle body principles called the bridge
design pattern.
In the handle class you have a delegate that points to an pure abstract
class(interface)
If the delegate points to an interface called implementor you have some
classes that implement the interface.

All,
I'm struggling with an OOP concept. Let me try to define what I'm wanting by
using some classic examples.
Let's say that I have classes called Square & Circle that derive from class
Shape. Within class Shape, it has a method called Save to save the object to
disk. It's defined in Shape because the logic to save the shapes is uniform
across all shapes.
Furthermore, let's say I've defined an interface called IDraw that includes

Hello all,
I've been trying to go over my OO Patterns book, and I decided to try
to implement them in Python this time around. I figured this would
help me learn the language better.
Well, I've gotten stuck with my first go at OO patterns with Python. I
guess it goes without say that some of the stuff that are taken for
granted in most of the books (ie. Interfaces, Abstract classes) don't
really apply to Python per say, but the idea...

Hi,
I have been stuck trying to come up with a design for days. I am working on
a small project regarding barcode and I want to implement a factory design. I
am now confused.
I decided factory pattern since I am dealing with EAN13, UPCA12 UPC8 etc.
Can someone provide a small sample on how to start. I have looked at the
factory implementation online but still can't figure it out. Can someone
provide a sample jsut to start with.

Hi,
I sent this message to the moderated c++ group too but it is
waiting for moderator approval and I wanted to send here too.
I am new to Design Patterns. I want to write a simple
DeviceManager which is only interested in CD/DVD devices. I want to get
the list of CD/DVD devices and "be informed when a disc inserted into a
device". I am developing this on Linux. So, I used HAL API and read
some system (actually /proc) files to gather...

The code below was taken from an example.
All the "noise" in the example was thrown out.
This is supposedly according to the bridge
pattern. What in the code (which lines)
represent the bridge pattern (make this code
to be according to the bridge pattern),
and what is the advantage of employing the
bridge pattern? It seems "l'art pour l'art" to me.

Hi,
I have a couple of questions about the proper design of classes.
I'll use a simple Customer class for my question.
1) Lets say that I have this Customer class like I said, and I want to
distinguish
between different types of customers, for example private, business,
other etc.
This will allow me to filter customers based on their type. Should I

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,...
