I have an order processing application with many features.
I want to be able to put some features in external and configureable
DLLs.
The main application has to pass an order object (and possibly some
other objects) to the external dll.
I have designed a base class with just interfaces on which the real
dlls base. The main application has a reference to this base class.
The external dlls (and the base class) need a reference to the...

designmode for the control is either true or false, depending on whether they

slider control that is supposed to be active in our form designer
(designmode=true) and inactive in our run mode (designmode=false). The

series of tasks. So far I have 2 group of tasks run on different threads (2

static field - Hashtable which holds key/value configs settings. So far,
application runs in debug mode without any errors.

Hello, I have a situation where I need to design a library for
multi-thread application, each thread does some work in a client

Now since it's a multi-threaded application, naturally I want the call
back functor to be created on a per thread basis.

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,...

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....

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...
