David Stevenson has just informed me that my article in the September issue of FoxTalk is available online: In this article, Colin Nicholls shows you how to extend the VFP 9 Report Builder’s Multiple Selection dialog with additional functionality you design. In doing so, he also reveals the secrets of the Report Builder’s lookup table, or registry, and demonstrates how you can substitute your own version to customize the Report Builder’s native behavior.

[Update: This article no longer appears to be available online. Sorry about that! For what it is worth, this feature has been revised for VFP 9.0 SP2 and although the technique is still valid for earlier versions of the product, you will probably want to pay attention to the changes when SP2 is released.]
