This chapter describes a utility that illustrates how to generate graphical images on-the-fly within a resource manager. You've seen web counters on various web pages; the count goes up every time someone accesses the web page. In this chapter, I'll show you how this can be done with a neat twist — the web counter looks and acts just like a plain, ordinary file. The "magic" is all done via a resource manager. You'll see how to maintain context on a per-open and per-device basis, how to handle the file content generation, and so on. The chapter presents the project in three phases — a kind of "building-block" approach.
