I have gotten some good ideas from some of the example code. However it is troublesome in that one does not know when the book can be trusted.

Chapter 17 . Optimizing VB Applications has a section Simplify The Math (page 942)which has very poor examples as to how to optimize code. One example which employs the random number generator Rnd() is hideously in error in that it is not only a less than optimum way to avoid the use of the power ^ , but it uses Rnd() two times which uses two different random numbers when the task was to square a function which used one random number.

The book provides good examples for advanced users, but is of little value to people who are trying to learn Visual Basic.
