Hello,
I would like to know whether it is possible to define static class methods
and data members in Python (similar to the way it can be done in C++ or Java).
These do not seem to be mentioned in "Learning Python" by Mark Lutz and David
Ascher. It seems like they are a relatively new feature... It seems to me that
any truly OO programming language should support these so I'm sure that Python
is no exception, but how can these be...

Why are there static methods in C#. In C++ static was applied to data only
(I believe) and it meant that the static piece of data was not a part of the
object but only a part of the class (one copy of data as opposed to multiple
instances of the class)
C# is now applying the static concept to methods. Why?, I thought that only
one copy of the methods were loaded into memory not matter how many
instances were created. Is this different...

Hi,
I'm pretty new to C#, and I'm quite stuck on the following problem.
I would like to add to my application a Windows.Form (singleton) on
which I could display a message of one of the following type :
Exception, Error, Warning, Infos (with differents colors, etc).
I would like to use it like the Console.WriteLine("My Message"); on
everywhere in my application.

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...

I have a global.asax file with Application_Start defined and create some
static data there and in another module used in the asp.net application and
I realize that static data is shared amongst child apps of an IIS
application and can be used by multiple users during the application life
cycle and for multiple page loads for the same or different page under a
root application.
What I don't understand and need to know is whether that...

I have a class that I want to make static but it uses some objects that are
instance objects. I keep getting a compiler error saying something about
using instance objects in a static class or method is not allowed. How do
you do this if you really need a static class but also have to use these
instance objects in them? If you need a simple example of what I am trying
to do, it is below:
imports Data.EternityRecordsEntities

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,...

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...
