ACCESS 97, Pessimistic Record Locking!???
Does Access 97 allow record level Pessimistic locking?
In other words, when user A is editing a record (has it locked) and
User B tries to edit it (attempts to lock it), user B will get
an error
saying this record cannot be locked now.
It seems like Access 97 is doing optimistic record level locking. In
above scenario user B, is allowed to edit the record but when tries to

Hi
To display a message when a user attempts to edit a record in a
multi-user environment where a forms Record Locking is set to Edited
Record and another user is editing a record, is difficult because
Access does not trigger an error, I have overcome this problem by
trapping the Delete and Backspace key in the KeyDown event of the form
and displaying a label on the form saying "If Record cannot be Edited
it may be that Another User is...

I have been ok with optimistic locking most of the time but I have a
situation now where there is more of a chance that users could try to
edit a record at the same time. I'd like to use pessimitic locking, but
it's not working quite as I expected. I've read all over, and by now
have posted elsewhere on this subject, and (strangely it would seem)
have made no progress. This seems to be a bit of a blank spot on the
map. (Access 2000-2003,...

Actually, it is not only the record locking, what I need, and nobody seems
to descibe this.
Imagine the following scenario.
There is a database with, say 10000 records with some unvalidated data. And
there is an Intranet ASP.NET application which is an interface to the
database in question... and there are 100 pretty girls eager to... uhmm...
use the application and validate the data of course ;-).
The task is to enable the data...

I have an Access 2000 database behind a threaded Java application that
that can have have concurrent access to the same table (but not the same
record). The database is set up for shared access with "No locks" as the
default, so that optimistic record locking should take place, and "Open
databases using record-level locking" is selected. Each Java thread gets
a new connection to the database, then updates its record.

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

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'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.
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...
