Access Members Of A Sub Class Through A Property Of The Parent Class?

Mar 30, 2010

This is a bit of a continuation from a previous post for which AtmaWeapon was very informative.

Problem:
A parent class has a sub class with various properties. A property of the parent class is a List(of T) with T = the sub class The issue is how to store data in the sub class of the instantiated parent

Some example code (hopefully formatted correctly):

Code:
'=========== Class Definitions =============
Public Class courseClass

Use A Private Class And It's Members From Another Class?

May 18, 2009

I usually use which is free, works a little too well, it's obfuscating the code that passes between my scripting class and the other classes, so after obfuscating the app, the scripting functions no longer work.However I found another obfuscator called Skater lite which is a free edition, it will only obfuscate private classes and members, so what I would like to do if possible is make most of my classes private and their members (except for the scripting class, which should allow it to work properly after being obfuscated), and somehow still use them globally, declaring an instance of the class doesn't seem to work, I'm not even sure it's possible and I know little about the scope of private classes, so anyone got any ideas or workarounds?

.net - Derived Class Members Not Available When Added To Custom Collectionbase?

Apr 28, 2009

I have a Base Class, called primitive Graphics. derived from this class are several different types of graphics, squares, rectangles, lines, etc. I am storing those graphics in an object that inherits collectionbase. This causes a problem because I cannot access any of the members in the derived class when they are added to the collection. Here is the default property for my primitivecollection class

[Code]...

My current workaround is to just put all of the public members in the base class, however this is starting to look ugly as I add more derived classes that need members available to the derived class only
