The internals of the class with const-qualified template parameter may differ dramatically from... .
Such compiler-generated casting can not be possible.
As both types are based on a template, both types are completely different for the compiler .
You can't.

Let's say I have a drive such as "C:\", and I want to find out if it's shared and what it's share name (e.g. "C$") is.
To find out if it's shared, I can use NetShareCheck .
How do I then map the drive to its share name? I thought that NetShareGetInfo ...

I'm not sure : WNetGetConnection will give you the path associated with a mapped network drive, but not the share.
SHGetFileInfo with SHGFI_ATTRIBUTES
upon return check the dwAttributes flag for SFGAO_SHARE.

Hello
How to convert shared_ptr that points to const object to shared_ptr that point to nonconst object. I am trying to do the following :
boost::shared_ptr<const A> Ckk(new A(4)); boost::shared_ptr<A> kk=const_cast< boost::shared_ptr<...
Answer Snippets (Read the full thread at stackoverflow):
The proper way should be this
boost::shared_ptr<A> kk (boost::const_pointer_cast<A>(Ckk));
'boost::const_pointer_cast' will do what you're asking for, but the obligatory second half of....
Use boost::const_pointer_cast , documentation.

That means your shared....
I don't know why this isn't supported, but it isn't .
No custom deleter.
Not a big one really, but some older api's like to return pointers that you must delete .
You must be in control of the allocation.
I know of at least two.

Boost::shared_ptr has an unusual constructor
template<class Y> shared_ptr(shared_ptr<Y> const & r, T * p);
and I am a little puzzled as to what this would be useful for. Basically it shares ownership with r , but .get() will return p . not...

It is optimization.
It is useful when you want to share a class member and an instance of the class is already a shared A ); shared_ptr<int> b( a, a->B );
they share the use count and stuff.

I recommend you setup share permissions as follows to avoid confusion:
On the share permissions themselves....
Make sure that you've assigned read permissions once you added user to a new group .
And see if that account can access the share.

If you've got more than a couple languages, you'll probably want to do this as an automation script to avoid driving yourself crazy .
You can export and import the string tables in either the General Information view or via the automation interface .

Across actual processes, you.
@grieve is referring to a global accessed by multiple threads, but threads share the same parent process instance.
Be able to share the values across running programs.
