Error in msvc in building inheritance.obj to build hello.pyd
Hello,
I am trying to build the boost 1.31.0 sample extension hello.cpp.
I can not compile the file inheritance.cpp because the two
files containing some templates: adjacency_list.hpp and mem_fn.hpp can
not compile.
Does anyone have any solutions?

Hi again!
I'm having problems with inheritance. I have a base interface class
called IObject. Next I have two other interfaces classes, IControl and
ICommandMaster, which derives from IObject.
My problem is that I have a /third/ class, CCommand, which derives from
both IControl and ICommandmaster...
The error message says (Weird.....)

Recently, I tried and did a poor job explaining an idea I've had for handling
a particular case of implementation inheritance that would be easy and obvious
in a fully OOP language, but is not at all obvious in VBA which lacks
inheritance. I'm trying the explanation again now.
I often find cases where a limited form of inheritance would eliminate
duplication my code that seems impossible to eliminate otherwise. I'm getting

Hi, I read about Master Pages in ASP.Net 2.0 and after implementing some
WinForms Visual Inheritance I tryed it with WebForms (let's say .aspx pages,
my MasterPage does not have a form tag itself so, cannot be called a WebForm
itself, the child pages will implement forms).
I created a Master.aspx page and removed all HTML from it, added some code
to the .aspx.vb file to add controls to my page. Then I created a Child.aspx
and changed the...

Some Sr. colleges and I have had an on going discussion relative to when and
if
C# will ever support 'true' multiple inheritance.
Relevant to this, I wanted to query the C# community (the 'target' programming
community herein) to get some community input and verify (or not) the
following
two statements.

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.

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...

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...
