Packaging a class?

Hey Guys,

First time on this site but I am sure you will be seeing a lot of me, months to come :P

I recently started a co-op placement for a software development position and it seems to be a bit of a challenge.
All the programming we have done in University so far never really went past the logic and programming. So the biggest problems I am having is more putting the program together nicely.

Now here is my current situation.

I have a block of code that reads stuff from text files and uses that info to fill up labels on a form. How do I package that block and have it in a separate part of the project. I do not want this to be in my 'main' file.

Do excuse my lack of appropriate terms. If any more clarification is needed let me know.

Thanks
