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

Hi,
I've got a VB.Net + ASP.Net message board application which has
already been customized. There are two solutions in this application.
1. The front end aspx, aspx.vb files, User controls solution
2. A components solution which has .vb files which have the code to
call inserts, updates, deletes to the database (SQL server 2000)
Its much like the available general ASP.Net message board. Only a bit
customized. Right now a simple...

what's the differences between collocated architecture
and distributed architecture??
My understanding is that collocated architecture has
everything in a single machine? i.e. There is only
1 machine in middle business tier?
But distributed architecture distributes the load in
multiple machines? i.e. There are multiple machines
in middle business tier?

Hi!
I am new to .NET (coming from Java). We have to implement a desktop
application which extracts data from a database, does some analysis,
filtering etc. and displays the results.
I have noticed that in .NET applications Windows widgets like the
DataGrid are often directly bound to a DataSet Object. For me this
means essentially a 2 tier architecture instead of a 3 tier
architecture. I am used to seperating the application into 3 tiers:...

This may not be a direct C# question, but since I'll be using using C# for
development, I thought I'd pose the question here.
I'll soon be involved in the design of a new software product that will
employ a software "Plug-In" architecture. Taking the plug-in route will
give us a design that can adapt to, as yet, undefined future requirements
(within the scope of the plug-in interface spec of course). In the past
I've done this with...

I have a small windows service which connects to a POP3 server at
defined intervals, scans the available messages, extracts the required
information and inserts the data into a SQL database. I am assuming
that this is not an uncommon piece of software.

the recommendations from Microsoft on developing Windows Services, but
to be honest I have found difficultly in...

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...

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,...
