object oriented languages. I am woindering if anyone can tell me why my
forward class declarations not working.
the member function findpaths can't seem to access the class Board

I put the Board class latrerbut also put in a forward...

I'm hoping someone can please help me remember the C++ rule: When
you're writing a header file for a class (say, some_namespace::Bar),
and that class makes use of another class (some_namespace::Foo),

This applies equally to function prototypes. Why do we have to tell the
compiler twice? Other modern compiled languages don't have this
requirement.
Just curious,

Hello,
I am trying to open a window containing an image and I would like
the image to be flush against the window -- i.e. have no padding or
border. Can I make this happen with a single call to a window.open
function? I would prefer not to create a separate HTML page. So far
all I have is the basic
var cwin = window.open('images/KJV-THANKS.gif',
'Thanks', 'width=243,height=420,');
cwin.focus();

How do I (portably) make a forward reference to a static (I mean
file-scope) variable?
I've been using "extern" for years, for example:
extern int x;
int foo(void)
{
return x++;
}

Hi all:
I usually make forward declarations in headers. Something like this:

Now, I need a reference to a type defined like this (traditional C Style):

Hi
I have a question on usage of forward declarations of templates. While
searching through this group , people suggested using forward
declarations and typedefs for templates as
// in myfile.h
template<typename T,typename R>
class some_class;

Hi all.
I have these classes, implemented as templates in header files.
Right now I have one file per class, where both the declarations
and implementations of one class are located in each file.
I would like to apply the visitor pattern to some of these classes.
One of the technicalities behind the visitor pattern is that one
needs forward declarations of classes, since there are two
class hierarchies which refer to each other.

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
