Hello!
I'm reading in a book about C++ and that is something that sound strange.
It says "Pointers have reference-assignment semantics similar to those in
Java. For example, after the assignment
Student* john = michael;
both john and michael share the same object. This type of an assignment is
different then value-assignmnet semantics used by class variables, as in

Hello,
Can someone explain me what is the differences between these 2 lines of
code :
MyArrayList2 = MyArrayList;
MyArrayList2 = MyArrayList.Clone();
MyArrayList/MyArrayList2 are aray lists of class objects implementing
the CompareTo() method, so the list is sortable.

Hi,
I wanted to perform a deep copy of an array. Searching on google I ran
into different opinions :

Hi,
I'm sure this has been asked several times before but I'll risk it ;-)
If I wish to save an Arraylist to another Arraylist and work on te
original without affecting the contents of the new or saved Arraylist, how
is it done. It always seems to create a shallow copy i.e. by Reference.
I even tried passing the original Arraylist to a function by Value and
return a copy....after an arraylist.clear on the original it still clears

Hello,
I am relatively new to C# but like it.
I have run into a problem to which I haven't been able to find
a solution despite looking.
I have an ArrayList that contains several RichTextBoxes (via Add())
I am trying to create a second ArrayList with this information,

I need to perform a Deep Copy on an ArrayList.
I wrote a small sample app to prove this could be done:
ArrayList a = new ArrayList();
ArrayList b = new ArrayList();
a.Add("Hello");
b = (ArrayList) a.Clone();

I have decided (see earlier post) to paste my Word doc here so that it
will be simpler for people to provide feedback (by directly inserting
their comments in the post). I will post it in 3 parts to make it more
manageable.
Below is a draft of a document that I plan to give to my introductory
C++ class.
Please note that I have purposely left out any mention of safety issues
in the ctors which could be resolved thru some combination...

The "C# Cookbook" (O'Reilly / Jay Hilyard), section 3.26, is on deep
cloning versus shallow cloning. The scanned pages of this book are
found here: http://www.sendspace.com/file/mjyocg (Word format, 3 pp)
My question, coming from a C++ background where deep copying is done,
is why in C# you would do either deep or shallow copying as suggested
by O'Reilly (using the "ICloneable" inhereited interface), at least
for the .NET framework.

Hello
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...
