Yep. Back when I used to teach Windows programming in C commercially, the course exercise was to replicate notepad. It was surprising how many of its features you could implement in a week-long course, especially as many of our clients were no great shakes at C.

I think it is more surprising how many deeper features were hidden in Notepad (I did a complete re-implementation using MFC for Windows CE).

Did you implement .LOG and Unicode support with BOM handling?

This was on Windows 3.1. I don't think the version of notepad there had any Unicode support - certainly the one in our training course didn't; I didn't feel up to teaching C, the Windows API _and_ Unicode. It was just a slightly realistic exercise where our clients could implement as much or as little as they felt happy with, making use of standard windows controls as much as possible.
