I have a datagrid with a dataview(created from a DataTable) bind to it. It displayes coordinates and I have a toolbarbutton that will create a set of new coordinates just like the existing ones, accept that the x-values is mirrored. It's also possible to remove these coordinates, by a method that removes any row with negative x-values. This usually works fine a few times, mirroring and then removing. But then suddenly the NewRow statement...

Hi All
I have a DataTable that has the AutoIncrement properties set, but when I add
a new row it doesn't use the values I'd expect and is causing an error.
For example:
MyTable.Columns("PKColumn").AutoIncrement = True
MyTable.Columns("PKColumn").AutoIncrementSeed = -1
MyTable.Columns("PKColumn").AutoIncrementStep = -1

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....
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...
