Windows.Forms. it was confirmed on several machines with Win2K and XP.

manager to see the GDI usage of the process. everything seems normal.
now catch the ListView's scroller and start to move it downwards. you have
to hold the constant speed so that the ListView is constantly repainted.

I have a working version of this in VB, tryign to translate everything over
to C#.
In the C# version this is filling the listview, the first couple columns are
ok, but the last few are going screwy.
In VB, it is working perfectly.
The reason for move is speed. Takes a full 10 - 15 seconds to run this on
VB, <5 in C#.
I adapted this from

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,...

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.
