Hello All,
Suppose if I have a SQL query like
select p.ID, p.NAME, p.UNIT_PRICE, o.QUANTITY from PRODUCT p ORDERS o
where p.ID = X AND P.ID = O.ID
Here one product can have many orders. Essentially Product is the master
table and Orders is the details table.

I was curious to know what some developers out in the industry are doing when it comes to exposing Data access logic, specifically persistence. This is assuming that your not using an O/R framework or something that completely abstracts you from the persistence details.
Are you:

I have a DataSet with two tables and a DataRelation. When I populate the
DataSet and define a master detail relationship through the DataRelation,
the grid bound to the master table shows both the master and detail rows
while the grid bound to the detail table shows the detail rows for all of
the master table rows. I would like the grid bound to the detail table to
show the detail rows related to the each master row as the user moves...

I am using WriteXml to output data to an xml file, and and XML web
control to display it. The code runs fine, however my groups are
being ignored. For Instance, the current output is:

<Table>
<PRODUCT_CODE>RM-Safety</PRODUCT_CODE>
<PART_ID>*61177-000</PART_ID>
<PART_DESCRIPTION>LABEL POUCH 1 PACK SOLO KR

I'd like to know if there is a best approach, in terms of using the Data Web
Controls (i.e. DataGrid, DataList & Repeater), for displaying data that is
the result of a query that joins two tables that have a one-to-many
relationship. For instance if I perform a query on two such tables, I might
expect that there would be data repeated on multiple rows from table on the
one side of the relationship. What I want to do is display an HTML...

I have an application with a list of questions, which are associated with
answers by a questId in a one-to-one relationship. The questions may come
from an XML file or a SQL Server database. The answers data will always come
from a SQL Server database. I am trying to use a DataList (preferably) or
Repeater to display the questions and update the answers.
I am using .Net 1.1. I have created a DataSet with separate tables for

Hi
I am trying to create a master/detail form. I have my master and details
tables dragged onto the dataset. I have also dragged the fields from master
table on the form which has created the navigation toolbar for me and which
works fine with the master table. I also have a dataview on the same form
ready for detail table but as yet not assigned to the detail table. How can
I now create a master/detail relationship between my master and...

Here's a strange situation:
I'm building an application that contains a One-To-Many relationship, and the application has a main form with a sub form to maintain the relationship for data entry.
In the "one" table are home page URLs of websites like:
www.BusinessSite.com
In the "many" table are URLs for other pages under the "One" domain like:
www.BusinessSite.com/folderName/PageInSite.html

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...

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....
Now, this would greatly impact the work of software developers. The idea...

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...
