Enhanced Collection

This code provides an enhanced version of the Collection class provided by VB. Features include: - Search/Sort capabilities, including support for a callback interface in your classes which allows customisation of this feature; - Update an item in-place, as well as move it within the collection with a single method call; - Fully persistable. You can save the contents of the collection to a PropertyBag or direct to disk; - Implements the existing Collection interface so it can be used interchangeably with the standard VB Collection; - Provides a second collection based on Strings instead of Variants; - And loads more! UPDATE 23 Oct 2000 - Fixed minor bug in Add method (occured when using a Before or After Index that didn't exist)
