Recently, I've been thinking hard about what makes code maintainable, and how to write code to be maintainable. This interest has partly been driven by the mentoring of those starting out in C++ that I've been doing, both through the ACCU mentored developers program, and for work.

The principles I've identified have not really been hidden; since they've been widely documented for years, and they're actually things that most good developers do as a matter of course. However, as with many things, you don't necessarily realize their benefits until you rediscover them yourself.

This is a collection of notes I have made while porting an application from MFC to wxWidgets. It is intended partly as a tutorial and partly to document some of the roadblocks I met on the way.

In this, the final part of the series, Jon rounds off the port of an application from MFC to wxWidgets.

In this article I will describe how an MVC approach to the generation of documents can yield the same benefits that are traditionally seen with this approach to software design, and will introduce some XML [XML][Harold-] tools that can support this method. Finally, I will look at some of the alternatives to XML that could achieve the same separation of concerns.
