Hi,
I have an inherited DataGrid, that does lots of extra stuff. For exemple
drawing a backgroundimage in every cell. The problem is that it's taking too
much time (using gdi+), so I want to do it using DirectX. I downloaded
already the DSK etc, but I can't find how I need to draw an image on a given
position. I don't need stuff to write advanced 3D-games, just painting that
image. Can anybody help me with this? I'm already looking for...

Can someone point me to an example or post some code on how to allow a user
to draw a rectangle on top of an image and retrieve the coordinates and
dimensions of it. They will also need to be able to move it around on the
picture and delete it.
Thanks

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.

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.

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...
