A powerful, succinct, at-your-fingertips reference, this second edition provides a portable tool for those learning Visual Basic 6, anyone who may not remember an exact syntax reference, or for programmers looking for new ideas.
This book is essentially an artifact. In the days before widespread internet adoption and search engines we had to rely on actual books for references.
Almost no one uses Visual Basic 6 anymore and even if they did there are probably more easily accessible resources available online. This book is essentially obsolete.
