When it comes to adding records in related tables, Access is really smart.
But when I try to do the same using ADO, I am really stupid.
Say I have two parent tables (eg Course, Student) and one child table
(StudentProgress). The course progress records how a student progresses on
a course. I have one course (History) and one student called Maya. I now
want to record her grade (64). If I do this in Access using a form, then
the form...

I want to create a query that the first field should be an autonumber. For example I want the name and last name from the Emp table, but I want that the first field is an autonumber that identifies the record so the results of the query should look something like
Field1 Name LastName

Using a Button to take an autonumber from one form to populate another
autonumber field on another form.
I have a Mainform "A" with a button and code that opens another Mainform
"B"
with a subform which has the same table as Mainform "A".
The button is supposed to tell the subform with the autonumber field

Can you issue commands from VB.Net to create and delete databases?
I would like to create, delete, and copy MSAccess tables and/or
databases from code. Can this be done? Can you show, or point me to
some source code? I'm a newbie.
TIA

I am new to databases and thus to Access. I have a situation where I am
trying to figure out how to key some tables I am working with. Consider that
I have a database of my own records which are invoices I work on. These
invoices are from four companies with their own invoice numbers. So, I
cannot key by invoice number because there is a likelihood of invoice
numbers duplicated by different companies. The records in this table of

Hi,
I want to use primary key IDs in my tables which are autonumbers, with a text prefix. I.e. for table tblVillage, the ID's will by V1, V2, V3... and for table tblHumanCases, the ID's will be H1, H2, H3...
I have a few questions:
1. I have heard its not good to do this. Is this true and if so why?
2. I am also having problems creating the relationships to related tables due to the field types. In the parent table the field type...

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...

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...
