I want to share enum between 2 classes C1 and C2:
class C1
{
public:
enum shut {AAA,BBB, CCC};
shut m_C1;
void set(shut &s) { m_C1=s;}
};
class C2 : public Cother
{
public:
enum shut {AAA,BBB, CCC};
shut m_C2;
};
void main()
{
C1 a;
C2 b;
a.set(AAA);
b.m_C2 = a.m_C1;
}
Is there a more elegant way than the one I have found, but for which I
do not measure the side effects :
class Cenum
{
public:
enum shut {AAA,BBB, CCC};
};
class C1 : public Cenum
{
public:
shut m_C1;
void set(shut &s) { m_C1=s;}
};
class C2 : public Cother, Cenum
{
public:
shut m_C2;
}; 4 3807

Yes. You don't need to make an enum a class member. Just put it on namespace
scope, and both classes can easily use them.

Thank you, sure I can put it at at a higher scope, but this may conflict
with other declaration at higer level, obliging me to declare :
enum shut { SHUT_OK, SHUT_ERROR, SHUT_AAA, SHUT_BBB...}
My idea is to keep programation simpler or shorter inside these (friend
or not) classes : OK, ERROR, AAA,BBB...

Thats why namespaces are there, to avoid such conflicts. Put the class
and enum declarations within a namespace.

One option:
namespace shut_t {
enum shut {AAA,BBB, CCC};
}
class C1 {
public:
typedef shut_t::shut shut;
void set(shut &s);
shut m_C1;
// ...

class C2 {

Hi, All,
I wrote a function to share a folder to individual user account with
WMI.
When I call it :
ShareFolder("c:\\test", "Test", "Shared by Riven", 8,

The folder will be shared, but nobody has permission to access it.
(The share permissions list of this folder is empty)
Could you help me?

So I was needing some extra power from my enums and implemented the
typesafe enum pattern.
And it got me to thinking... why should I EVER use standard enums?
There's now a nice little code snippet that I wrote today that gives me
an instant implementation of the pattern. I could easily just always
use such an implementation instead of a standard enum, so I wanted to
know what you experts all thought.
Is there a case for standard enums?

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.
