Hello Everyone,
I have a main form with a datasheet subform that I use to query by form.
After the user selects two criteria on the main form and clicks the
cmdShowResults button on the main form, the subform returns the records
based on the two criteria. The criteria used on the main form are values
selected in two list boxes. When the user clicks on the first list box
(lstCollege), it returns values in the second list box...

a particular field in a query, and assign a new numeric vaule to that

<form name="bambam">
<select id="fred">
<option value="1">1</option>
<option value="2">2</option>

Good day all, I am working on a multi-select list box for a standard
question checklist database and I am running into a syntax error in
the code that I cannot seem to correct. I will also note that I am
using Allen Browne's multi-select list box for a report as a guide. I
should also note that my access skills are not the best so I may need
some explaining on certain things.
First let me give some background on the database:

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...

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,...

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....

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...
