Hi Charlie..

You only have 15 minutes...

As far as OOP goes, when it comes to middle-tier development, VB and VFP are essentially the same level. Why? Because inhertiance plays little or no role in middle-tier work. As far as a flexible cursor engine goes, yes, that is an advantage of VFP. However, I don't think you can really demo that in 15 minutes.

Keep in mind, the goal of all the presentations is to show how to build COM components in the respective langauges. When it comes to showing what VFP can do, that the VB cannot do, macro expansion, IMO, is the best choice. For non-VFP'ers looking on, that, not the local cursor engine, will have more intrigue..


>Why show them what they already know? Show them what differentiates VFP from other products; its flexible cursor engine and OOP features.

>(5) Do some local data maniputation stuff like setting relations, indexing, filtering, etc.

>(6) Show how to create update parameters on the fly for your update stored procedures and integrate them into your base cursor class.

>(7) Show an XML class for creating XML strings that also also creates hierarchical XML from tables engaged in a relation.

>(8) Show them how robust VFP data can be on a LAN and how they can potentially save their customers a lot of money by avoiding SQL Server.
