I think I know the answer to this, but suggestions welcomed.

Hi,
I have a table with four columns.
By default, except for the second column (id="s01") all column values
are protected. When a value is selected from second column, the third
column is enabled. When a value is selected in the third column, the
fourth column is enabled and a separate button for adding a new row
(as in <trof code snippet above) is also enabled.

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:

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,...
