Hello all,
I have recently been porting code from Linux to cygwin and came across
a problem with static const class members (discussed below). I am
seeking to determine whether I am programming non-standard C++ or if the
problem lies elsewhere.
To summarize static const class members are not being accessed properly
when accessed from a DLL by another external object file (not within the
DLL). It only occurs when the static const...

The following program compiles fine but elicits this message from the
linker: "undefined reference to VarArray::funct" and thus fails.
It seems to behave as if the static data-member: VarArray::funct were
an extern, but it is declared in the same file (q.v.). What is the
remedy for this?

Hi all,
According C# Language Specification :
10.11 Static constructors:
The static constructor for a class executes at most once in a given
application domain. The execution of a static constructor is triggered
by the first of the following events to occur within an application
domain:
- An instance of the class is created.

Why are there static methods in C#. In C++ static was applied to data only
(I believe) and it meant that the static piece of data was not a part of the
object but only a part of the class (one copy of data as opposed to multiple
instances of the class)
C# is now applying the static concept to methods. Why?, I thought that only
one copy of the methods were loaded into memory not matter how many
instances were created. Is this different...

The following code snippet shows that VC++ 7.1 correctly compiles a static member function invocation from an Unrelated class, since this static member function is public. I expected to compile the same invocation from a DistantlyRelated class. What actually happened was that the compiler produced:
error C2247: 'A::function' not accessible because 'CloselyRelated' uses 'private' to inherit from 'A'
I'm guessing that the above compiler...

Hi all,
I've recently been following the object-oriented techiques discussed
here and have been testing them for use in a web application. There is
problem that I'd like to discuss with you experts.
I would like to produce Javascript classes that can be "subclassed"
with certain behaviors defined at subclass time. There are plenty of
ways to do this through prototyping and other techniques, but these
behaviors need to be static and...

Sorry in advance if this message sounds imprecise but it's difficult to
be precise when you don't really understand what's going on.
I have a class called Parameters. The default constructor
Parameter:Parameter() contains various values such as interest = 0.05;
My intent is for the user to be able to override these defaults so I
have a function
void Parameter::set(void) . This is supposed to give the user a chance

I see that static is more restricted in C# than in C++. It appears
usable only on classes and methods, and data members, but cannot be
created within a method itself. Surely this is possible in C# in some
way? Or maybe no, because it is similar to a global variable (with its
scope restricted) which C# is dead against?

like this:
class Base {
public:
int getType() { return type; }
private:
static const int type = 0;

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,...
