I'm trying to create a data layer and having problems returning a DataSet

a problem with is,...

I have used XMLDataToString = DataSetForXML.GetXml() to get an XML string
from a dataset. I am looking for a way to create a dataset from this XML
string. I tried DataSetForXML.ReadXml(XMLDataToString) but I received error
messages. Does anyone know how to do this without creating a file (disk
copy) of this XML data? Thanks for your help.

How do you create a third DataTable in a DataSet that is a Join of the two Previous DataTables

Hi
I have a sub method that has been passed a dataset as parameter. I need to
insert this dataset into a table. What is the code that I need to do this?
The dataset does not have any conflicting keys so it is a very easy scenario
from conflict resolution point of view.
Thanks

This is a question that someone familiar with ASP.NET and ADO.NET DataSets
and DataTables should be able to answer fairly easily. The basic question is
how I can efficiently match data from one dataset to data in a second
dataset, using a common key. I will first describe the problem in words and
then I will show my code, which has most of the solution done already.
I have built an ASP.NET that queries an Index Server and returns a...

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,...

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...
