Each and every tool is unique, but there are always core elements that are common to them all. Designing these core elements to be modular and reusable is advantageous and will save money and time when building subsequent tools that need the same functionality. Many developers build elaborate solutions to a simple problem, often reinventing the wheel in the process. These solutions are often complex and hard to maintain, costing additional resources that are better spent on other areas of an application that are more deserving of the time.

The chapters in Part II cover arbitrary elements that are applicable to almost any tool, independent of the feature list or specifications. The accompanying components to the chapters are also flexible enough that they can be plugged into these arbitrary tools with little to no modification. It is this reusability that will save a project additional resources that can be spent elsewhere. The majority of the chapters cover techniques that are relevant to the storage and manipulation of arbitrary data in a common form. Some techniques include data compression, encryption, printing support, using the PropertyGrid control, and a generic framework for handling batch file processing.
