There's a rather nondescript book called "Using Borland C++" by Lee
and Mark Atkinson (Que Corporation) which presents an excellent
discussion of overloaded new and delete operators. In fact there are
quite a few things that I learned that I did not know before. For
example, while I knew that the new and delete operators can be
overloaded for classes, I did not know that that the global new and
delete operators can also be overloaded. ...

Ok, thanks to some good assistance/advice from people in this group I've
been able to further develop my Distance class.
Since previous posts I've refined my code to accept the unit measurement as
a char rather than incorrectly representing it as an int. I've done this
because I want to develop the class so that it will be able to convert
between values, ie if I add 500 m to 1 km I'd like a correct result given in
metres (1500 m in this...

I'm trying to change the way a treeview works just a bit, i'm pretty new
to C# and now i'm running into overloading. I tried the following code
and it's yelling at me saying that no overload method takes 0 arguments.
#region tViewNodeCollection
public class tViewNodeCollection : TreeNodeCollection
{
private tView _owner;
private tViewNode _parent;

How is the best way to overload the New constructor for a form? For
instance, I want to be able to pass things to the constructor, or just
default with the plain New. Maybe say something like:
Dim x as New MyForm(parm01, parm02)
Should I just override new? What is the best way to do this for a form? (The
reason I am asking is it appears that the New for a form does a number of
things, like initialize controls, etc)

Hi,
I couldn't figure out the answer myself about the default constructor --
does C++ create it by default? If yes, under what circumstances?
Actually, I've found out the partial answer myself via trying the
following code:

#include <string>

Hi all,
Im having a problem with my code. Im programming a vector class,
and am trying to overload the () operator in 2 different situations.
The first situation is to assign values, e.g. Y = X(1,2), the elements
1 and 2 of X gets assigned to Y. In this case, the operator ()
overload should create a copy that is unmodifiable. In the 2nd case, I
want do assign values to elements 1 and 2, e.g. X(1,2) = Y. Then in
this case, the values...

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...
