Class: BoyerMoore in Category General VBA/VB6 : Searching and Sorting from Total Visual SourceBook

Class that implements Boyer-Moore string searching using VBA and VB6.

The Boyer-Moore string-searching algorithm provides a highly optimized method for searching for a sub-string within a string. The Boyer-Moore algorithm takes advantage of its knowledge of the string being searched for. By doing this, it is possible to search a string without examining all the characters in the string.
