Ok, I first want to stress that I looked through the newsgroups archives
(on Google) for an answer to my question, but I didn't find it.
It's about the interface of the set classes as defined in the PEP 218.
I don't understand why the sets has an interface of mapping object
without associated value and not an interface of sequence ?
For me, sets are first sequences. I use set where lists are inefficient
or inadapted, for example when I...

I'm using interfaces in C++ by declaring classes with only pure virtual
methods. If then someone wants to implement the interface they
needs to inherit from the class. If the implementing class forgets to
implement some method I normally get a compile error(if the class is created
in some way of course). When using the Visual
Studio 6 compiler however, it does not generate a compile error in this
case:
- I have a implementing class A...

Hi,
I have a WorkUnit class. I will pass a reference to a group of these
WorkUnits to other classes in my application. I have chosen to use a
vector to hold pointers to these WorkUnits for now.
However, I think that I should hide the fact that it's a vector in case
I want to switch to another container class at a later date. I don't
want every class that needs to use the group of WorkUnits to be too
tightly bound to the details of the...

Hi Group.
First of all I'm sorry for asking (maybe) such easy questions. But I'm
quite stuck now and couldn't come up with a solution by using my C#
book or googling. So it would be nice if someone could help me out.
Now first of all I want to describe the setting in a simpler (I'm using
Visual Studio 2005):
Form: One comboBox (dropdown list) and 2 buttons.
Classes: Class1 with a function do() which plainly returns a string.

Handle Classes
Handle classes, also called Envelope or Cheshire Cat classes, are part of the Bridge design pattern. The objective of the Bridge pattern is to separate the abstraction from the implementation so the two can vary independently.
Handle classes usually contain a pointer to the object implementation. The Handle object is used rather than the implemented object. This leaves the implemented object free to change without affecting...

I have a script that hides / shows form elements, and wrapped in a tab script (tab navigation). When the code is duplicated (per tab content), the hide / show function works for the first tab but breaks in each subsequent tab. Why? Help appreciated!
Example: http://geocities.com/edmurphy21/
hide / show script:
<script type="text/javascript">
function showHide()

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...

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...
