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

Hi All,
When I delete the last record from my dataset and then WriteXML() to the
file; the Table itself, in the xml file, is removed. I need to prevent the
table structure from being deleted if there are no more records to be
written to the XML file from the Dataset.
Any ideas here,
John.

I am having problems understanding how to access a datasource only
once, fill a single dataset, and then reference that dataset multiple
times through different user controls(ascx) found on the same page.
My main page(aspx) contains multiple user controls. The main page also
contains a publicly declared dataset. At the first instance of needing
data I call (from an ascx) a function that fills the dataset and then
returns it to the...

Hi,
I am having trouble determining if my dataset is empty.
I have function that populates a dataset from a database and then retuens
it. If the database contains no data then the dataset will be completely
empty, and then when I go to databind() it to a combo box and error will be
throw.
What I whould like to do is check the dataset from code to see if it is
empty.

I am having no problems connecting to a DB, creating a DataAdapter,
and creating a dataset...and connecting to the data. Using the
builtin data objects to do all this.
My only problem now is navigating through the data. I can get the
data into a datagrid without any problems, but I want the data to show
up in textboxes and use some sort of move next, move previous, move
last, etc (like in VB6) command to navigate the data (using...

This is a 2 part question:
Part 1:
I am accesing a web service that returns an xml string of user information. I am attempting to load the XML into an XMLDocument, save the document, load it into a dataset, and bind the dataset to a gridview.
I'm not sure if it's neccesary to save the XML file to disk, but I wanted to make sure it was well formed. It is.
No exceptions are caught during the loading and binding process, but my gridview...

Hello all,
I am programming an embedded controller that has a 'C' library for using
its system functions (I/O, timers, all the specific devices). The

How can I dynamically load a LIB file and access all its functions?
Surely someone has solved similar task?
My intention is to use a Forth system for programming the controller,

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

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,...
