I'm trying to port code from VC.net to VC.net 2003. Here's a typical
piece of code that's often used:

typedef T::iterator iterator; // this line will change in the next
example...

What the heck - I can't find it. A bit shocked to see it missing though.
So "Does VB.NET have the yield keyword, or any equivalent of it" ?

This is an old problem of mine.
Basically I have an abstract base class which represents a generic iterator
over a collection of elements, and various derived classes that implement
the traversing on specific data structures.
For each iterator I want to be able to specify the four possible const
combinations, corresponding to the various void* for
pointers, with the possibility to perform conversions from non-const to
const just like...

Help! I am writing an image processing package. For
one constructor, I allow creating an image from a
map of points and color values. The points are
of a "position" class and the colors are just a
vector. It starts thusly:
template <class T>
image<T>::image(map<position<int, vector<T >& in_map){
cerr<< "***** ***** ***** ***** ***** *****\n";

I have read about input, output forward etc iterators. But if I make the
following:
int myints = {1,2,3,4,5,1,2,3,4,5};
std::vector<intmyvector (myints,myints+10);
std::vector<int>::iterator forward_iterator = myvector.end();
I can still type "--forward_iterator" eventhough "--it" is illegal on
forward iterators.

Apologies for cross posing this but I am not sure if this is a VC 8 STL
bug or simply an invalid use of the iterator.
I have a PCI card access class which basically abstracts a third party
library from the higher level classes. This low level class is used to
allocate locked pages of memory before doing a DMA. The third party
library locks memory and returns a pointer to an internal structure,
which we can simply cast to a (void...

According to the Python docs, once an iterator raises StopIteration, it
should continue to raise StopIteration forever. Iterators that fail to
behave in this fashion are deemed to be "broken":
http://docs.python.org/lib/typeiter.html
I don't understand the reasoning behind this. As I understand it, an
iterator is something like a stream. There's no constraint that once a
stream is empty it must remain empty forever.

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...

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. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
