Hi all,
I have a process, where I take a dataset from an SQL call, and need to write
an XML file from that dataset.
The data set can contain 10's of tables, each with 100's of rows, and I have
no way of knowing what the tables are, or what they contain.
I am currently using the Dataset.WriteXML method passing an XMLWriter.

Hi,
I've got a simple console app that just reads an XML file into a DataSet
then prints out a description of each table in the DataSet, including
column names and row values for each column. I'm getting some strange
results depending the input XML file I use. I was wondering if somebody
could help me understand what is going on or point me to a good reference.
The code for my program looks like this:

I am using the ReadXMLSchema method of system.data.dataset to read a schema into a dataset.
I have an XML file that I build up and wish to do a .Update against a database.
The dataset doesn't have a schema and takes the following form:
xml:
<?xml version="1.0" encoding="utf-8"?>
<DataSetEntities xmlns:ms="urn:schemas-microsoft-com:xslt" xmlns:guids="urn:schemas-microsoft-com:guids" xmlns="C:/DACXML/EntityAttribute.xsd">

I have a web interface where the user types in ID's one at a time. After an
ID is typed in, a button is clicked and the button click event has code that
does a query and returns a data reader and then appends the data to a
dataset that is built in the Page_Load code in the if(!isPostBack) block.
When I try to add a row in the button click event code I get an error saying
that "Object reference not set to an instance of an object". I'm...

I've just discovered a bug in some code I wrote a little while ago, and I
need you guys' help to fix it.
My program imports data from a standard Excel Spreadsheet (just with
specific column headers). I used ODBC in my VB.NET program to read that
spreadsheet into a dataset, to make it easy to manipulate. The code I use to
read it is as the bottom of this posting.

I have a dataset that is returned from a sql server select that contains
metadata and a cached dataset saved in an xml column. I would like to
recover the dataset for use in generating a crystal pdf file. the
rptds.ReadXml method can accept either a string file indicating a filename
or a stream. the row.ToString() is the saved dataset. If I use
this directly it throws an error because it is data and not a filename. I

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....

I'm a network technician in training and I need your help.
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...
