I am using Javascript for a drop-down menu, slightly adapted from
one by Angus Turnbull (see http://javascript.internet.com and

it deserves a plug ;-), on Internet Explorer v6.0.2800.1106.

Hi,
I'm designing an interface for a shared library, and I would like to
know if there is a standard about how to return an object to the user. I
will use exceptions to report errors, so there are at least four ways to
do it.
For example if we have a method named M, that receives a reference to
parameter p and returns object o.

Hi all,
Sometimes I have a function which creates an object and returns it.
Some are sets, other vectors but that's not very important. In these
cases I do something like this:
vector<int> * f() {
vector<int> * v = new vector<int>;
return v;
}

How do I return a references to an object from a function?
static ArrayList getItemFile(string destdir){...}
Does the above code return the whole Arraylist on the stack or does it
return a reference?

I'm implementing an algorithm and the computational flow is a somewhat
deep. That is, fcn A makes many calls to fcn B which makes many calls
to fcn C, and so on. The return value of the outermost fcn is a boolean
and there are certain places within the inner functions where it may
become apparent that the return value is false. In this case I'd like
to halt the computation immediately and return false.
My current approach is to have...

Hi all,
I am trying to get my head around what happens if I return a class
object from a function.
It seems C++ (MinGW) does not invoke the copy constructor if I do
something like this:
SomeObj foo()
{
SomeObj X;

Since delaration of C++ the r/l-valueness of objects has been source
of confusion there are some actions that can perform on lvalues but
not on rvalues , especifically on initrinsic types .BTW the programmer
is not capable of defining special interface for classes based on the
r/l-valueness of the object(the way we do for const/volatile).Move
proposal - about Hot(rvalue) refernce - has been an attempt to get
that different behavior at...

I remember there was a thread a while back that was talking about using the
return value of a function as a reference where I had thought the reference
would become invalidated because it was a temporary but it was stated that
it would not. This has come up in an irc channel but I can not find the
original thread, nor can I get any code to work.
Foo& Bar( int Val )
{
return Foo( Val );
}

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...

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....
Now, this would greatly impact the work of software developers. The idea...

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...
