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 need to expand the DataSet class by inheriting from it and adding
functions that work on the data in the tables. However, since I can't
upcast how can I get my base DataSet object assigned an actual
DataSet?
e.g.
public class MyDataSet : DataSet
{
// can't do, no valid DataSet constructor

Hi,
I need to pass a dataset to another win form along with a SqldataAdapter.
I don't want to recreate the SqlDataAdapter again either. So to pass to
another Win form in my windows form app, do I create the procedure to pass by
ref? Which means I don't need to add ByRef because it is defaulted by ref,
correct? And in the constructor of the win form that gets created. I need to
add in parameters a DataSet and SqlDataAdapter correct? What...

I am having problems understanding how to access a datasource only
once, fill a single dataset, and then reference that dataset multiple
times through different user controls(ascx) found on the same page.
My main page(aspx) contains multiple user controls. The main page also
contains a publicly declared dataset. At the first instance of needing
data I call (from an ascx) a function that fills the dataset and then
returns it to the...

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...

hello,
i have a web app that allows users to query our oracle db and produce a
dataset of report data. they then have the option to serialize this
data and store it in the database. later, then can re-run the report
and get fresh data. now, they would like to be able to compare the
fresh data to the stored data, getting a break-down of
added/deleted/changed rows.
on the surface, this sounded plausible -- by deserializing the stored

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
