I'm sorry, I must have not described my question correctly. Reading it again, I could have really simplified it.

What I want to do is create an application that has data files of a specific extension, and when I open the data files it launches the application and loads the data. For example, when I click on a .doc file it launches Word and loads the document. I know I can make files of that extension open with my application, but I don't know how to load the data.
