Hi,
I have three classes:

Each of these classes stores its information into
a database table of <ID, text>. (They are fields
that have a foreign key.) There is only one
table for each instance of these classes (IOW,

Hi,
I find myself using static methods more than I probably should, so I am
looking for some advice on a better approach.
For example, I am writing an app that involves quite a bit of database
operations on purchase orders and inventory. I have created a PurchaseOrder
class and Inventory class to encapsulate operations like creating POs,
finding items, etc. These two classes are used extensively from different
parts of the app.

So I'm working on a project for a C# class I'm taking, where I need to
keep some running totals via static variables. I need three classes
for three different types of objects. The base class and inherited
classes are all identical. I need to refer to the static variables in
each class, and each must maintain its own values for each static
variable.
Now: when I inherit my base classes, the static variables in all my
classes contain...

Hi all,
I've recently been following the object-oriented techiques discussed
here and have been testing them for use in a web application. There is
problem that I'd like to discuss with you experts.
I would like to produce Javascript classes that can be "subclassed"
with certain behaviors defined at subclass time. There are plenty of
ways to do this through prototyping and other techniques, but these
behaviors need to be static and...

In the baseclass in one of the static methods I need to do something like

I have a class with bunch of static methods. I could regourp all the
static methods into seperate 3 or 4 classes. I was thinking about using
Singlton pattern for all these 4 classes so that it behaves like static
still class. But my concern is, when going from static to singlton, I
need to add one more line to make sure the class is instantiated.
Am I going in right direction?
Thanks for the help.

In my app, I have two very similar static classes. After long
thought, I've decided *yes - keep them static*.
- Sometimes I will want to use Static Class A, and somtimes I will
want to use Static Class B, depending on the situation.
- The interfaces (are interfaces allowed on static classes?) are
almost identical.
What's the best way in code to create some sort of "factory" that will

As we know, the keyword "inline" is a bit misleading because its
meaning has changed in practice. In most modern compilers it has
completely lost its meaning of "a hint for the compiler to inline the
function if possible" (because if the compiler has the function
definition available at an instantiation point, it will estimate whether
to inline it or not, and do so if it estimates it would be beneficial,
completely regardless of whether...

It looks like static classes can have non-static member classes --
does it make sense what I just wrote? If not, let me illustrate it:

private struct Bar{

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...

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.

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...
