Dear NewsGroupers,
I am relatively new to OOP and cannet get my head around this problem.
I have two classes. Class Child extends Parent.
There is no constructor for the Child class. So when I create a child object
the constructor for the parent object is called. That works fine.
But now I have the problem that I want to add an already existing Parent
object to create a new Child object. How can this be done?

Is it possible to instantiate a child class within the constructor of its
parent?
eg
Class DBI extends DB {
function DBI() {
// explicit parent constructor call

How is it possible to take the value of a variable (in this case,
MODE_CREATE, MODE_UPDATE, etc) and use that as an object property name?
In the following example I want 'oIcon' object to have the properties:
mode1, mode2, and mode3.
This seems simple but I can't quite figure it out...
Any ideas anyone?

I need (okay, I want) to make a dynamic array of my class 'Directory',
within my class Directory (Can you already smell disaster?)
Each Directory can have subdirectories so I thought to put these in an
array. The application compiles but aborts without giving me any useful
information.
What I suspect is happening is infinite recursion. Each Directory
object creates an array of Subdirectories each of which has an array of...

I am a newbye, and I'm trying to write a simple application.
I have five tables with three columns; all tables are identical; I need to
change some data in the first table and let VB updates the same data in all
other four tables in the right places.
