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.

I'm very new to developing in .NET and even newer to XML. The past few days
have been pretty frustrating for me because I'm trying to perform a transform
on data in a dataset and it's not working.
Basically, all of the data is stored in an Access .mdb that is read into a
dataset when the application is loaded. There are some minor changes to the
schema between what is in the physical database to accomodate some things

I have a dataset that has DBNull in certain columns, now when I write
out this one to XML, I only get the columns as elements that do have
data in it. However I do need also the empty colums as empty elements
in the XML. How to do that ?
I don't understand why there is no simple option to specify the output
format, or did I miss something ?

Hi all,
I've seen that many people have had this exact same problem in the past, but
no-one seems to post the answer when (if) they solve it... so here we go
again.
If I create a strongly typed dataset from an xsd schema I've created in
VS.NET 2002, instantiate and populate the dataset and write it as XML using
WriteXML() the generated XML file is not valid based on the xsd file used to
create the dataset.

I have data coming from SQL Server and need to write out some XML. I
have a schema(xsd) for this XML file. Right now I am bringing in the
DataSet and writing out the elements and attributes myself using
xmltextwriter to match schema without really using the xsd at the time
of writing.
The file I create validates but I was wondering is there a better way?
I see things like inferschema method off of dataset, can this be used?
How do you...

and use WriteXml method to create XML document. Problem is XML tags come out
in the order that is different from the order of tags in the XSD. My client
requires that XML validates against XSD, and the use XMLSPY to validate it.
I ran the same test and XMLSPY complains that tags in the wrong order. Is
there a way I can force order of tags with WriteXml method of...

Hello,
I have an application using an xml dataset to store app and user settings.
The problem I am having is related to writexml. I have a save button on my
application that updates the dataset and then using the writexml(...)
function saves the dataset to an xml file. I have noticed that the file does
not change everytime I click the save button. I get no errors but the
writexml function does not seem to be updating the xml file.

I've got a DataSet that I save as XML using the DataSet DataTable's WriteXml
method.
If I say XmlWriteMode.IgnoreSchema, it shows up great in Excel, but I can
not reopen the file in my application because there is no schema for it.
On the other hand, I can choose XmlWriteMode.WriteSchema, and the data in
Excel looks more like some kind of code instead of the data: id=NewDataSet,
name=NewDataSet, ns1:IsDataSet=TRUE, etc. If I open this...

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:

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,...
