Hi,
I have a corporate database with about 60 different tables that spans
manufacturing, accounting, marketing, etc.
It is possible, but unwieldy, to establish a relationship for each
table in the entire database through critical fields like customer_id
or product_id.
But should I do that?

I have an Access 97 database with 2 tables that have a one-many
relationship. I have a SQL statement in the "one" table which I want to
execute and insert 7 records into the "many" table, and I want them to be
linked to the "main" table.
Problem is, it won't let me run the SQL run as long as the one-many
relationship is established in the relationship window.

Hi,
I have created a dataset schema(*.xsd) which contain two element
"InvoiceHeader" and "InvoiceDetail".
I set the primary key of both the element. for example "InvoiceHeader" -> id
and "InvoiceDetail" -> "id, date"
Then I created a relationship between both these item using the key "id".
This create the one-to-many relationship.

Hello!
I'm trying to create a dataset with a relationship inside a class, so
it can be used on multiple pages.
If I create the dataset in the class and define the relationship in the
page, it works perfectly. If I create the relationship in the class
itself, it doesn't work.
The only thing I can think of is that on the page I declare the

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
