The text further explores programming for the multimedia and pen capabilities inherent in the NT operating system.

The book is presented as a technical guide for experienced programmers seeking to optimize their applications and adapt to newer Windows environments. Its focus on advanced topics and specific platform transitions suggests a readership interested in deep technical dives rather than introductory concepts. The inclusion of source code indicates a practical, hands-on approach to learning.
