I'm sorry about this verbose posting. This is a follow-up
to my yesterday's posting. Thanks William for your reply.
I understand it is a good practice to open connections as
late as possible and close them as early as possible.
My requirement is as follows:

by a COM component. My class library contains functions
that perform lot of mathematical calculations and read a
lot of data...

I read in a Visual Studio .NET book that with C# it is now recommended to
open database connections whenever you need to query a database as opposed
to the traditional method of opening a database at the start of your app and
closing it at the end. Their reasoning was that "opening a database
connection is no longer an expensive operation".
Do you guys agree?

Hi,
I have an windows forms application that accesses a SQL database
I have a few questions as to connecting to the database.
This application will run 24 hours a day. It is a monitoring application and
will store events that happen in the database (These events happen randomly
without pattern, between 10-50 a day) .
There are a number of situations where the database is accessed.

I've been working on an asp.net application and everything's been great.
But suddenly, whether I'm tyring to use a database on my own machine, or on
my server, I'm getting a timeout when trying to open a database connection.
The error seems to happen regardless of what ASP.NET app I'm working
with/trying to debug.
It will open a few connections,

Hello,
I have postgres set to log all connections. I run it on port 5432. I
have noticed in the postgres logs that the port being used to connect to
the database is logged but never equal to 5432. The ip address recorded
is correct but the port number recorded is always a different number
each time.
This is 7.4.1-3 on cygwin. Has anyone noticed this on other platforms?

Hello!
How does this connection pool function actually ?
As I have been told is that when the connection is returned to the pool
the connection to the database is still open. What you do is that you just
return a still open connection to the pool.
When I open a connection I get an already open connection to the database.
Is this correct understood ?

In an ASP.Net v2 web application that connects to a SQL 2005 database.
It appears that it is not closing the connections to the database and
leaves 100 db connections open and then the application can not open
any more connections.
Why is the database connections still active (sleeping in activity
monitor) despite the code closing the connection?
How can you enable application pooling for a web application?

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...
