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.

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 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 ?
regards
andreas

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...

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.

Hello!
I did search for this one quite a while, but I cannot seem it mentioned
anywhere, so let me ask here if someone saw this problem before. The
behaviour is confirmed (for me) with Framework Version 1.1 (with all patches
for the version applied)
I read and write data for an XML file into a dataset, the file is around 13
MB, and contains one table with around 1000 entries (rows) with maybe 12-15
fields, the fields are sometimes a...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
