Dynamic objects in C++ are managed explicitly by the programs you write. The Localized Ownership pattern language Tom presents, however, does the job for you.
by Dan Zigmond
STL iterators--objects that function more or less like conventional pointers--are used as the interface to data structures. Dan explains how iterators are central to the C++ Standard Template Library.
by Terris Linenbach
Understanding relationships between objects is crucial to the success of any object-oriented software project. Terris presents a design for binary association that consists of both OMT and dynamic-model diagrams. He then implements the design in C++, using templates to promote code reuse.

The IOU pattern provides a simple, intuitive way to add asynchronous behavior to applications. Since the IOU pattern is independent of any specific concurrency mechanisms, it is applicable to many different concurrency methods--and it's implemented in Java.

VHDL is a hardware-description language that frees you from low-level details. Phil uses VHDL to design an interface between a PC's parallel-printer interface and a high-speed data-acquisition system that can generate several million 8-bit data samples per second.

Deciding how to handle blocking I/O is essential when designing programs that use the Winsock interface. Our authors present a method for removing the blocking network I/O function calls without having to rewrite the application from scratch.

Encapsulation comes to Quincy 96 as Al starts by grouping debugger operations in a Debugger class. He then turns to "Herman," a general-purpose document-viewer program written in Visual C++ with MFC.

How do you write a Java-based chat program? Cliff shows you how, starting with a C++ server and Java client.

Decision trees are used in such diverse applications as bird-watching guides and medical-diagnostic programs. Andrew presents the ID3 algorithm, which uses an information-theoretic metric to build compact decision trees.
by Scot Wingo and George Shepherd
Scot and George show how you can customize the MFC print preview and print-status dialog. They also highlight some techniques for working with undocumented MFC classes that weren't really designed to be customized.
