Hi,
A default copy constructor is created for you when you don't specify one
yourself. In such case, the default copy constructor will simply do a
bitwise copy for primitives (including pointers) and for objects types call
their default constructor.
Any others points i should know?

On my cmdSaveRecord, I check a couple of fields to confirm that an entry has
been made before allowing the Save.
I decided to
- not put validation rules in table structure, and
- validate on Save
to avoid annoying the user if a field was left empty before clicking
cmdSaveRecord
For each field validated in this way, I was getting an error something like

Is there a way I can have a button on a ASP.NET form that when clicked will
allow the user to save the image to a file on the client side? I know that
the user can simply rclick the image and select Save Target as..., but the
button might be a more intuitive way.

Hi,
I need a SECURE way to copy parts of a file. I'm having files which contains
a whole bunch of records. In one 'fysical' file I'm having one or more
logical files.
What I need to do is to copy a logical file (a part of the fysical file)
into a new file. But the 'big' problem is: these records contains
bankstatements, so I can't take the risk that there would be a record
missing, or even one little charachter. The copy I make has to...

I have several Data Structures, say "mystruct" which contain arrays of bytes,
other structures, etc. I then dimension a variable (var1) as "mystruct" and
set the various elements var1 to data. I then dimension another variable
(var1save) as "mystruct" and set var1save = var1 with the intent of changing
var1 data elements and subsequently reasigning var1 back to it's original
values of var1save.
VB.Net makes only a shallow copy of var1...

Is it possible to save a copy of cout the same way you can save a copy
of stdout in C (I know C version is portable, but unix portable is
good enough for me).
I have to use a library which closes stdout on init because its used
to mostly in background processes but I need it for an interactive
process. Library cant be changed unfortunately.
I tried the following but the C++ version doesn't work, I guess
because it only shares the...

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