Hi,
Given a collection of similar but not exact entities (or products)
Toyota, Ford, Buick, etc; I am contemplating using the Abstraction pattern
to provide a common interface to these products. So I shall have an
Abstract Base called 'Car' implemented by Toyota, Ford, and Buick.
Further I'd like to enable to client to say
Car *factory;

Hi all
I have code for an object factory, heavily based on an article by Jim Hyslop
(although I've made minor modifications). The factory was working fine using
g++, but since switching to the Intel compiler it has stopped working. I
think the singleton pattern static instance thing may be at the root of the
problem, but I'm not sure. I had to add calls to instance() in regCreateFn,
which gets the behaviour more in line with what I was...

In Febraury - April of 2002 I put together in Java examples of all 23
of the classic "Gang Of Four" design patterns for my website. Partly
I wanted to get a better understanding of those patterns. They are
still online at
http://www.fluffycat.com/java/patterns.html
Since September 2003 I've mainly been using PHP, and now that PHP 5 is
becoming more available I am going to try the same thing I did in Java
with PHP.

Hi all!
We're creating an administration for a web application. This includes
severeal aspx pages.
Our key entity in the web application is "Profile", which can have a
certain type.
Based on the profile type, the administration pages will have some
small changes, such as displaying a few extra tabs, or maybe change
the available choices in a dropdown.

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.

I am using the factory method to solve a problem where a factory can produce
product.
I have a base factory class and a base product class. The problem that I am
having is that for every product subclass type I am having to create a
factory subclass to handle differences in logic. They are becoming one to
one. Is this ok? Should I look at another pattern to solve the problem?
abstract Product
Product1: inherits Product
Product2:...

Hi,
I am a fairly seasoned developer and have recently started looking at
software design patterns. I am starting with the Abstract Factory Pattern
and was wondering if someone could help me understand where I might use this
Pattern. I get the general concept but I am having a hard time converting
that concept into where I might use that in a real world scenerio for a
business application or web development project.

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,...

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
