These are example projects geared to the second edition of my REALbasic book. Most of them are simply source projects demonstrating example code in the book, and will serve to clarify what the book is saying, or save you the effort of re-typing the code. Some of them improve upon the book's example code, occasionally in ways that were not feasible in a printed medium. A few of them didn't make it into the book, for one reason or another.
If you have the book, you can consult these projects easily by chapter. You'll have to guess from the file name what piece of code in the book is being demonstrated, but that shouldn't be difficult.
If you don't have the book, you can use the names of the chapters and projects to give you a sense of what they exemplify. If you are looking for an example of how to do something in REALbasic, you should be able to find the right project here.
Be sure to consult the list of examples on my home page as well. Those examples demonstrate numerous techniques and devices that I didn't feel it worthwhile to repeat here.
Bear in mind that you will need REALbasic 3.2 (beta or final) to open these projects. All projects have been tested under Mac OS X; if a project doesn't work there, because of a REALbasic bug or some other difference between the systems, this fact is noted in the project.
