I am running the code below to generate XML from a data table. But some
fields in the data table are Null for every record. Suppose field5 has a
null database value. I would expect to see:
<field5></field5> or <field5 />
but instead it doesn't even show the field at all for those records where
field5 is Null! Instead it just shows:
<field4>Whatever</field4>

Hi,
My problem: Merging two datasets deletes parent elements, preserves
all children.
I've created two dataSets. Each use the same schema, parent-child
nested tables.
The first dataSet is loaded with historical data read from an XML
file. The second dataSet has current data filled from a dataGrid.

I want to bind three elements of an seven element arraylist to a data grid.
I cannot find an example of complex binding specific fields of an array list
to a datagrid.
Any examples would be appreciated.
m_Stat = new Stat(str1,str2,str3,str4,str5);
m_arrlstStats.Add(m_Stat);

Hi, i'm experiencing strange problems with the datalist webcontrol.
I have it bound to a datatable like this:
Me.TreeNodeList.DataSource = _existingNodesTable
Me.TreeNodeList.DataBind()
which does contain the elements i want to display. The problem is that
the final output looks like this:

My page has a Listbox called Rooms, a text field called chairPerson and
a button called Add.
When Add is clicked, the script needs to display the selected info in a
datagrid.
For example, if the user selects Rooms 1,5 and 7, and enters Bijoy for
chairperson and clicks Add, a datagrid on the page should display the

On an Asp.Net webpage, what's the best way to go about managing a list of
items?
When editing a library title I display a DataGrid of authors to which I'd
like to be able to add and remove. Ideally, I'd like to be able to work with
the list within a single page and not save the list until pressing an OK
button.
Should I keep a list of record IDs in a Session variable? Or postback the
list of IDs in the Request? Is there a way to...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Hello
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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
