First of all, I'm really sorry for my english, hope youll understand what I'm asking for... :-) I need to define a class contains fields as strings and integers, a constructor, properties and Set/Get function. In main(), I need to creat an object of this class and access it's info. I need to create a sub-class (I think it's called this way... which goes by "class x:y" syntex...), to add fields in it, Set/Get function, properties, and define an object in main(). I know it sounds lots of work, but actually it's nothing for you guys. I'm not asking you to write one especially for me, but if you have an example code - i'll be gratefull!!! Thank you in advance!
