At the risk of sounding like a Big 5 consultant, "It

1) Strongly typed datasets rock, they are faster than
untyped, use intellisense... but your reason for
wanting to use them is important. I use them every day
of my life, but I also don't use them every day of my
life and there are reasons for both.
2) How much of your process is dependent on reads vs.

I have a small Window application and through out the different forms I
create a different dataset. At the begining I used the Tools to drag and
drop the SqlDataAdapter, connection and dataset objects to the frist few
forms but then later I removed those and created these objects in my code.
I now see 3 datasets in the Solution Explorer panel part but not all the
datasets that I have in my codes. Are these 3 datasets leftover from the...

I've always used untyped datasets. In a Microsoft course, it walks through
creating typed datasets and harps on the benefits. It has you drag all
these things around ..wizard, wizard, wizard... code gen, code gen, code
gen.
What's at the end looks slick, but then there's a ton of generated code that
I'm going to have to maintain now.
I.e. I like typing things myself (don't like wizards) so I can know exactly
what I've done.

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

Hi all gurus.
I'm trying to switch to VS 2005, from VS 2003. I've an ASP.NET 1.1 app
heavily relying on StronglyTyped DataSets, with lots of FindByKey...,
dataSet.Tablename, and similar methods. Converting to ASP.NET 2.0
leaves dataSets' classes unconverted, as stated by M$; what's worse,
I'm not able to use converted dataSets, nor new ones, but just non-
typed dataSets declared directly in pages (or code-behind), and so I'm
not allowed...

Hi all;
as posted some days ago, I'm converting an on-line app; I used to
heavily rely on strongly-typed DataSets directly dropped onto pages,
and so viewed by code(-behind) as well. In the next two weeks I
discovered that such objects are no more directly usable in pages,
namely in DataGrid which don't see them any more. Even if rebuilt in
Component Designer, and so visible in code, DataSets are invisible in
Page Designer, so now it's...

I'm trying to decide if it is better to use typed datasets or business
objects, so I would appreciate any thoughts from someone with more
experience.
When I use a business object to populate a gridview, for example, I loop
through a datareader, populating an array list with instances of a custom
class in the middle tier, and then send the array list up to the
presentation layer and bind the gridview to it.
If I use a typed dataset, I...

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...
