not any particular field has actually changed
2) running a second SELECT statement and comparing the $_POST vars to
the returned values, and only UPDATING those that have...

pass variables to the separate Thread or Runnable that I'm using. I'm

tables with enormeous number of updates and insert and the use of
checkpoints (for simple recovery and Backup Log for full recovery).

pace of growing can't keep up with the update. Therefore we want to
create a script which flushes the...

Unless my app is EXTREMELY simple, I get the cross-threading error message
regularly when updating controls on a Windows form.
My latest example involves a dll that runs a System.Threading.Timer,
updating private shared variables. When it finishes updating, it raises a
NewData event. My app responds to that event by updating display controls
(labels in this case). I have to use a delegate and update them like this:

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:

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.
