hi,
I would like to lock a record so that when one user is modifying a
particular record, then it is locked for all other users. For this
purpose, I have two fields in every table ("LockedBy int null", which
contains the UserID of the editing user and "LockedSince int not
null", a timestamp).
My current logic is: when the user enters the form to modify a record,
lock it (set LockedBy=$UserID). when the user presses the submit-button

"An explicit interface implementation of an event must use property syntax"
Here is a code sample:

Hi,
I have noticed that every aspx page that I created (and ascx file) has an
assosiated resource file aspx.resx.
However what I would like to do is have a single global resource file for
the site.
The resources in this global resource file will possibly change quite often,
there I guess this rules out using web.config as every time web.config
alters the application is recompiled, also I am not sure of the possible
consequences of...

Hi All,
I am working on the situation where 2 different
Process/Application(.net) tries to open file at the same time....Or one
process is updating the file and another process tries to access it,
it throws an exception.
How to solave this problem? So second process can wait until first
process completes its processing on the file.
Thanks in advance

Hi,
I have several processes accessing files from one folder, but only
one process should ever access each file. Once one process has the
file, no other process should be allowed to access it, even after the
first process is finished with it, except in the case where the first
process crashes. In pseudo code..
* Open file with exclusive lock
* Process file - failure will throw exception, skipping 'Remove

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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.
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...
