I'd like to cite a few examples. This is no longer an area for just the tool vendors - we can all do it now. Templates are used widely in BCB 4, and can prove very confusing if you've never used them. The authors are quite successful in leading the reader from an understandable introduction through the basic concepts. This is not a description of all the available functionality, but having read the chapter, you'll be able to easily take it from there.
Threads are cool, but they can be very intimidating.
This is good stuff, even for those of us who think we know what we're doing. Although not a complete reference on the subject by any means, the chapter does do a good job explaining simple and multiple threads, parameter passing, mutexes, threaded database access, and priorities. After reading the chapter, I was very glad to know of all the capabilities available in this richly dressed class. Most of the work of a true word processor is available in this one component, with very little programming. Without this book, I doubt I'd have noticed.
