I am reading in xml files that equate to sql tables, via XmlDataDocument,
and then operating on the DataSet. With the most simple app that just loads
the xml doc, I see the memory footprint of the app grow to roughly 5x the
size of the xml document after the xml doc is read. Can anyone comment on
this? Is this expected?
Below are two samples, the first hits northwind, and creates a 19meg
(roughly, on my machine) xml file. The second...

I have successfully loaded a DataSet object with a XML schema (XSD).
Now I wish to populate the tables that was created in the DataSet.
I have an XML file/string that contain all the needed data in the same
format as the XSD (the XML file/string was created using this same schema).
The XML file/string may contain data for a single table or for several
tables at once.
The question is:

Hi all,
Would someone be able to tell me the most 'graceful' way of removing
unwanted rows from a dataset based on a condition prior to update? OR,
resetting the rows all to unchanged after they are initally added to the
recordset.
I create a dataset, which begins empty after the initial .Fill.
Then I create several rows with some default information, leaving one

I have my SQL database with a table that I am trying to have a
gridview dislay with inline editing.
It seems as if the dataset does not generate the apropriate update
query, and therefore consequently the gridview does not automatically
allow editing.
I then try to change which update query that is selected being the
dataRow, DataSet,dataTable or other DataRow And none of them work

I have a dataset with Customers, Orders, and Items tables.
It has datarelations set between Customers-Orders and Orders-Items
It has foreignkeyconstraints with update/delete rules set to cascade
for Orders & Items.
The dataset is filled with Customers and their related Orders and
their related Items.
What is the most efficient way to create a second dataset that is a
subset of the main dataset, but only has data for Customer_id = "1"

Hello, I'm trying to figure out how to create a Crystal Report in VB2005 using a CrystalReportViewer from a dataset that I created on a form Form1. The dataset (from an Access Database) appears on a DatagridView on Form1, assuring me that there is nothing wrong with thre creation of the dataset itself. However , I cannot make it appear in the Report Viewer. The error that constantly throws up is : "Report has no tables". This is my code :...

I have a wizard on a page that will dynamically create a dataset as it goes
along based on user input. When the wizard is done, it will dump all of the
data it collected/created in the wizard to an xml file. Should this be an in
memory version or a dataset or a file based dataset?

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'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.

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...
