I am writing a program with MS Visual Studio .Net 2003, which reads
data from a MS SQL DB. Reading the data is fine, but when I push
update, so it writes the data, it get the error message invald cast
System.Byte to System.Byte ? It'll happen even if I just add/change 1
character in a field already present.
Does anybody know what that means? And why it happens maybe?
Thanks,

Evening,
Wondering if someone can point me in the right direction, on how I would
compare a system.guid with a system.byte.
system.guid (pulled from sql server table with a data type of
uniqueidentifier, originally taken from objectGUID from active directory

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...

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,...

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...
