Every time I create ASP.NET pages that do any significant data access, I
find myself having to deal with the same problems: managing data object
creation, the SQL connection object especially.
Problem 1: If I have a pile of data adapters on a page, I typically only
need a single SQL connection object, though the designer always tries to add
a new one for each data adapter. So I have to manually weed out the extras
and set the data...

set of name, value pairs time-stamped and associated with a device.

How do I add a watch, using asp.net in visual studio, to stop the program
when a value in a drop down list changes? I can add a watch through Debug,
windows, watch, but there doesn't seem to be a way to have it stop the
program if and when the value changes, I never see it in the watch because
the program ends before the value changes.
I have stepped through my entire code, and at the very last second of the
program a drop down list...

Are there any way of detecting that a program have crashed and left an
orphan file?
I have tried with the filesystemwatcher, but that didn't work.
Maybe I can use a polling strategy and keep polling the file and check if it
is locked. But can I do this without trying to open the file and catch
exeption.
Any suggestions are welcome?

I have a question:
When should syslog.closelog() be called? I have a daemon that spends
most of its time asleep and quiet, but writes messages to the mail log
when active. Should I open the log at the start and keep it open until
the program closes? This seems much simpler than issuing three
commands everytime I want to write to the log.
The program will essentially be running constantly. Is having the log
constantly "open" a...

In Access VBA, the immediate window only displays a couple hundred
lines of my debug output. How do I display more lines there, for
example 500 lines, or even 5000 lines? Is there a way to set the line
size in access VBA?
How do I see the complete content of a string variable while I'm
debuging without writing code to output it? The values in watch window
is truncated.
Thanks a lot!

I have a program that is reading one of my mailboxes.
It is polling the mailboxes ever 5 minutes to see if there is a message or
not.
Is this how Outlook does it (using Exchange as the server)? It doesn't seem
to. When a message gets to Exchange, it seems to do some type of Push to
Outlook as Outlook has it immediately.
If so, ss there a way to make my program do that in VS. We are getting

Hey there, this will be somewhat a long post, but any response is

I have done many PInvoke in the past from C++ to C#, but I did PInvoke
within C# not C++/CLI.
Can someone explain more why C++/CLI would be better to PInvoke than doing
the PInvoke in
C#?
Because, usually in C# as you already know we use DLLImport and extern

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
