Hi, I'm trying to modularize my database connections a little better and get
more out of my project with less code.
First check out this common dbOpen() function inside class clsDatabase. I
removed the try/catch part as it is not important for my question:
// This function opens a connection to the database.
public static SqlConnection dbOpen()
{
// Create a SqlConnection object and pass in our connection string

Hi,
I have a C# Solution/Application that contain 4 projects.
Each of these projects needs at some time to access the same database.
I would like to know how to share a single connection between these projects
as i assume this would be more efficient than having a separate connection
string for each project.

Hello,
I'm just starting to develop in asp.net and i have a question about
using a database connection globally in my app. I have set up the

will use, but my question relates to how to use the database
connection i create in all my classes.
I have a database class, in a separate namespace and file, i created
that handles all the connection opening, executing statements...

Hallo!
I'm working with C# .NET 2.0, implementing Client/Server Applications which
are connecting via Network to SQL-Server or Oracle Databases.
To stay independent from the underlaying Database I use
System.Data.Common.DBConnection and .DBCommand.
How can I keep aware from connection losses (network not availeable,
db-server not available...)?
Are there any strategies to detect this broken connections, and how can I

Web Solution
Goal: Have a global database connection
Why: (There will be 30+ tables, represented by 30+ classes) I only want to
reference the database connection once.
I put the connection string in the web.config.
I created a class with a static database connection and the class opens and
closes the database.

Hi all,
I am creating a website in which in an Item detail page there are a number
of web controls (7 or 8) and what is happening that inside each of control's
Page_Load() function I am creating a database object to query data from
database (using MySQL database). So it means that for each page request I am
using 7 or 8 database connection which is something quite bad as far as
performance is concerned. So please tell me how can change...

the following:
In the main form load I open a connection using a connection string that I
stored in a global variable g_sConnectionString and leave this connection
open and not close it until it exits the application.
Then on each thread/each subsequent sub that needs the connection I create a
local OleDBConnection variable, open the connection using the exact...

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...
