I've got Javascript in a form that adds up all of the numbers in a
column of form fields and displays a total. It works great if every
field has an initial value of 0, but if any of them are null, "NaN"
displays as the total. I tried to add a test for a null value with
the intent to skip adding that field to the accumulator for one
iteration of the "for" loop, but it doesn't work. Can anyone tell me
what I'm doing wrong? Below is the...

Hi,
I have a Schema for a Dataset which I am populating from Excel.
One of the columns is a string datatype. When I Fill the Dataset I want any
Null values to be set to a string value.
I have seen varies articles using this namespace
xmlns:codegen="urn:schemas-microsoft-com:xml-msprop"
This allows you to use the codegen:nullValue="" in the xs:element of the
Schema.

I'm trying to set up a hierarchy system in this database where each row
can be related to a previous row. The problem is that when I go to
addTreeRow, it doesn't allow me to use Convert.DBNull for the childof
column, even though I have nilable set to true. (All parent nodes have
to be set to null, since they are not the child of any other row...
especially the very first row, which will have...

Hey folks,
I am attempting to pass null as the input value from a series of
textboxes if the user does not input a value prior to submit. To try and do
this, I am using a vbscript function on this asp as follows:
CommentsAdd = IIf(Request.Form("Comments")="",NULL,Request.Form("Comments"))
I was hoping this would convert those emptystring textboxes to null.

Hi,
I'm using XmlSerializer to create an object from the XML string. I
would like to know whether I can get a null value for an empty XML
element.
Actually the XmlSerializer assigns "" (empty string) for a string
if the corresponding element is missing in the XML.
Input XML:
<DemoClass><A>some value</A><B></B><DemoClass>

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.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
