STL Toolkit – The STL Toolkit is a high performance implementation of the ANSI/ISO Standard Template Library (STL) and includes String, Exception and Utility classes.

ETL Toolkit – ETL Toolkit contains a unique set of collections packaged to enhance the STL. It includes Sorted Vector, Dynamic Array, Hash Table,
Heap as well as List, Stack, Queue, and Set structures.

Foundations Toolkit – The Foundations Toolkit consists of a Thread library for writing multi-threaded applications, a Helper library that includes STL helper functions and a Time Library with 64 bit time and date classes.

Communications Toolkit – The Communications Toolkit contains eight class libraries: Streaming (platform independent object serialization), Network, Pipe, File, Security, IO, Framework, and UNIX.

Web Toolkit – The Web Toolkit enables you to write web page logic and structure with C++ objects and existing C++ interfaces. The Web Toolkit supports HTML2 and HTML3 web page elements.

Math Toolkit – The Math Toolkit provides prewritten performance-oriented, scientific-computing solutions.

Database Toolkit – The Database Toolkit provides programmatic access to a wide range of ODBC-compliant databases.
