Hi,
I have three classes:
Category
Author
Publisher
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,

I have this giant library, it's static and it's all compiled in __fastcall
fashion.
I can not call any of those functions from winforms...
even doing a wrapper off the main class, I still cant call it....

I've got an 'third-party' library that had an library.sln for 2003.. I've
opened that in VS 2005. I've modified the library and the test application
that are part of that to enabled exceptions (the exceptions that where
being used didn't work with /clr, so I changed them to the kind that did),
and then I enabled /clr for both of them. The library builds fine, but
then the test application fails to link with it (#using failed to load...

Hello,
I have a large legacy MFC application. As is typical, there is an
executable along with several MFC DLLs. One of these DLLs is created by
staticly linking in many libraries resulting in one very large DLL that has
the bulk of the code.
I've downloaded the MFCWinFormsSample.EXE and have noticed that the main app
could stay as a native executable (i.e. no CLR support) whereas the various
..DLLs can be marked as having CLR...

I'm wondering what some of the important considerations are regarding
implementing the DAL as a static class vs creating instances of it as
needed.
I'm writing a .NET 2.0 Windows application (MDI) that will communicate with
a SQL Server; approximately 120 users.
On smaller apps I have tended to implement the DAL as a static class. But
this new app will likely spawn background threads periodically to update
business objects throughout...

Hello everyone,
I've been trying for some time now to move to C++/CLI, but I have several
large legacy C++ static libraries I need to use. When I set up a simple
solution with a C++/CLI Winforms app and a C++ native static library, they
work well together _unless_ I have, it seems, any static variables defined in
any function in the native library.
The libraries I'm trying to use all have Meyers Singletons in them, so they
need to have...

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...

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...
