We've been developing a web site using 3-tier architecture for 18
months now.
There is a common layer that defines the classes - using XML schemas.
The data layer acts as a wrapper to 3 databases - SQL Server, Oracle
and AS400.
The business layer exposes web services which communicate with the
front end, ASP.Net. All 3 tiers are on different boxes. This works
well.
Now I am leading a team to build a winforms app. I need some advice as

I'm new to using .net and data access logic components and I'm getting a bit confused on the best way to design the data layer. I have a table called Document that has a 1 to many relationship with the Reference table. A reference is unimportant outside the context of its document. When displaying the document, I need to display all of its references and when updating the document, I need to update its references. Is it appropriate to place...

I'll make it brief: are DALC (Data Access Layer Components) and DAO
(Data Access Objects) the same thing? They appear to be from what I've
read on MSDN. I'm quite familiar with the DAO pattern from my J2EE
background and was trying to figure out if this is just Microsoft just
giving a new name to an old pattern or if it's something I should be
looking into instead of DAO.
Thanks,

I am writing some 'Data Access Logic Components'. The designer generates
procedure InitializeComponent(). Within this procedure an OleDbConnection
object will be created and assigned to all commands. My problem now, how can
I use a global allocated connection object, because I need transaction
support over more than one DALC ? Code generated by the designer should not
be changed manually, because it could be thrown away during a new...

I am in the beginning phases of architecting a multilayered ASP.NET Extranet
application and am thinking it might make sense to implement the DALC layer
as a singleton and expose them to the Business Objects layer via Remoting.
Are there pros or cons to this approach?

I have an issue where the below operation works on a little-endian
architecture but not on a big-endian architecture. I was under the
impression that pointer arithmetic is architecture independant and
bitwise operations are architecture dependant. The intention is to
store two bytes, as chars, extracted from a short input parameter as:
<code>
void foo(short id_pair)
{
char *ptr = &id_pair;

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...
