Hi,
I should use XML to synchronize the data from different (VB.NET)
applications, and I was just wondering which Overloads of these functions
( ReadXmlSchema, ReadXml and WriteXml) goes the fastest? I don't think the
ReadXMLSchema would give a lot of difference, but maybe the overlaods of
ReadXml and WriteXml will. Especially with larges files/datatables...
Should I use the IO.Stream? The XmlReader/XmlWriter?

I am writing the file correctly and it gives me the right xml file
When I read it back, I am missing one element in the last row, it sets
it to the initial value before I saved the origional file? Any ideas?
Thanks,
I am loading the xml file with this code;
Dim myFileStream As New System.IO.FileStream _
(filename, System.IO.FileMode.Create)
' Create an XmlTextWriter with the fileStream.
Dim myXmlWriter As New System.Xml.XmlTextWriter _

I'm attempting to use ReadXml. It's working in that I end up with some
data in the DataSet. But I'm not able to deal with it effectively after
that. The XML file is properly formatted in that it was created with
WriteXML, so it contains the name of the table (I've inspected it to be
sure). But after calling ReadXml the DataSet does not contain a table
with the specified name. In fact, Tables does not contain a table
corresponding to...

Hello,
There is a space(as a data) in one of the columns. And i save my DataTable
as a xml file using DataSet. I used DataSet.WriteXml method to save as a xml
file. Now if I read that .xml file using DataSet.ReadXml method,it removes
space in that DataTable. Any idea...?
This does not work in Visual Studio .NET 2003. If I execute this in VS .Net
2005, it works. I must make it work in VS 2003.

I am using WriteXML/ReadXml pair to save DataSet for later use. DataSet
is built by reading textfiles and storing their data to different
DataTables. Each file contains several complex values, that are
represented using a DataValue object. DataValue is an abstract class,
that has subclasses that implement the value (for example; ValBlkValue
represents a vector of floating values).
Class DataValue implements IXmlSerializable interface and...

Hello guys, I have a pretty simple app that reads XML data (.ReadXML)
into an in-memory dataset, runs some linq queries, mods the data, and
then writes the XML (.WriteXML) back to disk.
Everything works well until, occasionally, I get an
OutOfMemoryException. So far this has only happened for a file that
was about 50MB in size. All other, smaller files are working just
fine.
50MB (+overhead of other objects etc...) certainly does not...

Hello!
Assume the following :
1. I create a DataSet with some DataRelation.
2. I then use WriteXml to write the DataSet to an Xml document using
DataRelation.Nested = True
3.I then read the Xml document using ReadXml to load and create a DataSet.
Now to my question is this DataSet that was created from 3 the same DataSet
with the same structure

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,...

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....
Now, this would greatly impact the work of software developers. The idea...
