Well, if you used my builder to create a classlib of CAs, you could add thjis feature quite easily to the CA baseclass in the VCX. Then all the CA subclasses would have the benefit of creating any indexes that you may have specified in this array using your coe in the AfterCursorFill. Heck, I might even incorporate this in my builder.

Since they are created without indexes I will need to create some indexex if I want to use Relations or do an incremental lookup etc. I am thinking that always creating and deleting these indexes may be a performance problem.
