This document provides an introduction to creating and using classes in C#. Key points covered include defining classes with fields, methods, and constructors; using accessibility modifiers like public and private; calling methods and using the this keyword; creating static methods; and using listboxes, comboboxes, and events for selection changes. Examples are provided for defining classes, constructors, static and instance methods, and populating and accessing selection properties of list and combo boxes.

A proposal I wrote for "Lemasr", an organization for supporting development in Egypt. I thought the information contained within might be useful to more people.

This document provides an introduction and overview of inheritance in C#, including:
- Inheritance allows classes to extend existing classes, inheriting members and behavior
- Derived classes can call base class constructors via the base keyword
- The protected keyword controls accessibility for inherited members
- Virtual and override enable dynamic binding and polymorphism by allowing derived classes to override base class methods
- Abstract classes define common interfaces for derived classes to implement
In 2010 we had the idea to have multiple graduation projects with common themes. The themes selected for that year were "Arabic NLP" and "Pen computing". This presentation outlined the two themes and suggested several project ideas for them (and some GP ideas not related to the two themes),
