In the past we have used the classic nTier design with COM+, SQL Server
and MFC. We are currently working on a new project with an opportunity
to use .NET, ADO.NET, etc. One of the areas where I don't find a clear
migration path is with security. In the classic method, the server
side tiers were installed under COM+ and run as a known user. SQL
Server then gave full access to this known user so ADO simply needed to
make standard calls...

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 know how this should be done in regards to nTier, but it seems a bit
inneficient, and was wondering if there's a solution that I havn't thought
of yet.
(I'm switching this loop to For Each Row as DataRow in.... to kill the one
int that's not needed.)
For intCount1 = 0 To
objData.DataSet.Tables("tblSecondaryNumbers").Rows.Count - 1
rowTemp = objData.DataSet.Tables("tblSecondaryNumbers").Rows(intCount1)

I understand the concept of and the purpose of breaking up the application
in to
seperate modules (or tiers) for reusabillity and ect.
What i dont understand though is what exactly needs to be on a data access
tier.
For example I am working on a project right now that i was thinking of making

Hello,
I have an NTIER Model written in VB.NET, at the moment is running as a
client / server. Pushing a pulling data from the client to the server is
fine and is done via webservice calls. But how do I go about a call from the
server to the clients ?
An example would be that the clients are using a disconnected dataset and
need to be informed that the dataset has been altered and needs refreshing.

I have an ntier application.
I am trying to determine what is the best practice for handing errors in a datagrid.
My datagrids are able to add, update and delete data. I am using a objectdatasource to access a proxy which calls a remote business object. The objectdatasource uses a custom class to pass the data to the business layer.
The business layer method returns true or false.
When false is returned I want to be able to handle this....

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...
