The main rationale I have seen for namespace support in XML is to
enable the peaceful coexistence of XML fragments from various
sources within the same ("heterogeneous") XML document without
their trampling over each other's namespaces.
What about the validation of such "heterogeneous" XML documents?
Not only are various fragments probably governed by different
syntaxes, but these syntaxes are probably specified using different...

I defined a base class in order to put heterogeneous values into a
standard container: All values that I store in the container are
derived from my base class.
Now when I iterate over the elements of the container and want my
original values back - can I avoid excessive casting and if
statements? (see my sample code below.) Can I make it more elegant?
#include <iostream>
#include <vector>

All,
I have quite a challenging task ahead of me. I need to write an object model
(for code access) based on a schema, which cannot be made into a dataset
because of it's complexity.
So I created a couple of objects and serializing it into XML based upon the
schema works perfectly.
The XML / Schema looks something like this:

I want to save a struct to disk.... as plain text.
At the moment I do it with a function that just
writes the data using fprintf. I mean like this:
fprintf(fp, "%d %d", my_struct.a, my_struct.b)
This way I have to write another "serializing"
function for every new kind of struct I want
to write, though. Is there a way to write
functions that can write/read any struct
to/from plain text format in a portable way?

Hi,
I am writing a messaging library which will allow me to send a generic
message structure with custom "payloads".
In many cases, a message must store a non-linear data structure (i.e.
"payload") using pointers. Examples of these are binary trees, hash
tables etc. Thus, the message itself contains only a pointer to the
actual data. When the message is sent to the same processor, these
pointers point to the original locations, which...

Hello,
I have several drop-down lists on my ASP.NET page. I need to keep data
sources of these lists in Session State.
What would be the most effective method to serialize this kind of data
structures?
Thanks for any hints,

Hi all,
I've got a question related to emulating aspects of polymorphism
with CRTP. Below is a typical polymorphic class hierarchy with
a definition of a "somewhat" heterogeneous container of objects.
class poly_base
{
public: virtual int foo(int i, int j) = 0;
};

This is one of those nice, permissive Python features but I was
wondering how often people actually use lists holding several different
types of objects.
It looks like whenever I need to group different objects I create a
class, if only so I can use more meaningful names than '' for the items.
How often do these show up in your code?
Is this simply the upshot of the underlying arrays holding only object
references of some sort?

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...

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,...

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.
