I'm doing my best to learn ASPNET from a book devoted to ASPNET 1.0. So far,
I haven't run into any problems, until now.
This is a simple page that should just show the sql strings created by the
CommandBuilder (or is it data adapter) object.
Here is my code (the books code, actually):
<%@ Page Language="VB" %>
<%@ Import Namespace="System.Data" %>

If I add the code for user to download the file (e.g.
if(File.Exists(FILE_NAME)){......}), the ASP.NET will give the
following timeout error:
Timeout expired. The timeout period elapsed prior to completion of the
operation or the server is not responding.
It seems that the download file code is executing before letting the
previous code to finish. Even the message print code
(message.Text="...";) is not executed.

The problem
I'm using the .NET GridView and FormView objects for the first time and
im getting the error "An OleDbParameter with ParameterName '@ID' is not
contained by this OleDbParameterCollection" whenI try to write a new record.
Delete and Modify work fine its just the add record function causes the
error.

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.

Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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.

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...
