Hello,
what is the best way to prevent the user of a class from making copies of
objects of this class? Making the copy constructor private is a solution but I'm

Thanks,
Wolfgang

Hi,
I've seen javascript code where a constructor function is passed an argument
"document", and inside the function itself the assignment "this.document =
document;" is made. This is the code (or the part necessary for the
example):
function ToggleButton(document) {
ToggleButton.images = new Array(4);
for(i=0;i<4;i++) {...

in response to external stimuli. While that effect is obviously
possible via other means, I attempted this method first and was
surprised when it didn't work, so I now want to know why :)

Profiling has shown that during runtime of my program, 100 million
objects of class X are constructed and destructed.
What is the best way to optimize in such a case, both for memory and
speed (speed maybe more important)?
One idea is to make the class very small, to contain only the most
important member data, and put everything else,...

I understand the concept.
Serialization of a class will add all the sub-objects of the class to
the stream if there are also serializible.
So say I have:

Dear ladies and gents,
I'm trying to determine whether the .NET Framework implements a means
of transactional processing without the need for a database.
Essentially, I'd like to enlist light-weight portable business objects

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.

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.
