I am developing a Windows Forms application in VB.NET that will use .NET
remoting to access the data tier classes.
A very simple way I have come up with is by creating typed (.xsd) datasets.
For example dsParts.xsd and including that in the data tier. I then will
create a class that looks like this
Public Class CPart
Inherits dsParts

Hi,
I have a situation where I need to convert business objects to a flat table.
The reverse is also required. I am using c# and
Oracle ODP. I am looking for an easier method to do the below steps.
Steps I follows for populating Business Objects is as follows
(1) Get a list of records containing various tables joined together from DB
using a single PL/SQL
(This is a specific requirement, So cannot change the design)

Hi all,
I am hoping that someone with some experience developing nTier apps can give
me some advice here.
I am writing an nTier web app that began with a Data Access Layer (DAL),
Business Logic Layer (BLL) and User Interface Layer (UIL).
The problem I found with this was circular referencing...

I am new to 3-tiered design and am in the process of designing an
application that will work with ASP.NET as well as Windows Forms (and
possibly with a PDA of some sort down the road). My question is about
the statefulness of business objects. In some of the examples that
I've seen of 3-tiered systems using ASP.NET, the business objects are
recreated every time they are accessed. They are not kept in the
Session variable for use next time...

hi guys,
Currently converting an old classic asp system to a OOP asp.net
application. We are building the new application using a 3 tier
arcitecture and i was wondering about the following.
I have a parent class, that when inserted, inserts a few child classes
into the database, based on other classes. In the old system, this is
wrote as one big SQL script, with many inserts and updates because the
system was not wrote as OOP.

Hello,
I'm in a front of very serious .net redesign/rewrite of an old VB6
application.
I had been asked to make it .NET 2.0 and would like to ask couple of
questions regarding data access as this application is heavily data-centric
around MSDE database.
Would it be better to use custom business objects or extend

Hello, we have an ASP.NET website which uses NT authentication to
authenticate against an AD server.
We then have a set of business objects which are used to store /
retrieve information into database tables.
The business objects retrieve the connection string from the
web.config and use Integrated Security to connect to the database
e.g our connection string looks like the following

Hello:
I am trying to find what is the very best approach to business objects
in Windows Forms. Windows Forms presents an awesome opportunity to use
DataTables and I would like to continue doing so.
I have worked with dynamically generated DataTables with customized
DataRows. However, these classes are usually pretty limited. For
instance, you are limited to a select few data types and you can't
deal with nulls as well as desired (in...

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

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,...
