Problems storing objects in a vector and incrementing a staticcounter in C++

>MyClassCounter <<endl;

Hi All,
>
BACKGROUND INFO
I need to use a "vector" structure to store a number of objects that
becomes known only at run time. The constructor, at instantiation time
of a new object, increments a static counter. The value of this
counter becomes the ID of the object that has just been instantiated.
I am using Visual C++ 6.0 and, for this project, in the short term I
have no options about this.
>
PROBLEM
I have done this countless times in the past (90s) with large number
(100+) of objects without using a vector. Now I need to be able to
handle a much higher number (>10000) of objects. I need the use of a
vector because I need to run various loops on all objects. When I do
it, it does not work.

MY CODE
==============
I am showing below:
1) File TestOne.cpp
2) File MyClass.cpp
3) File MyClass.h
4) Screen dump of execution
>
WHAT I GET
=========
It seems that the static counter is not accessible from within the
vector. See "4) Screen dump of execution". Actually, it seems that the
static counter is accessed once and never again.
>
QUESTIONS
==========
1) Am I doing something wrong? What?
2) Can anybody be so kind to show me the correct code?
3) If, for whatever reason, it cannot be done using a vector, what can
I do?
>
Thank you.

Best regards

First of all, there is absolutely no reason to write "this->" in the
member
function. Then, the copy constructor could be:

As about the this-in a member
function, again, you are right, but I have to abide by the coding
standard set by others.
