For my research queue:

I should look at the below ConnectionStrings to access dBase with ADO from Delphi, If I ever need to do that.

Thanks Cromulent for asking, Nelson for editing and Pieter for answering:

Microsoft dBase ODBC driver

Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;OLE DB Services = -1;Extended Properties=dBase IV;Dbq=c:\mypath

doing operations like ADOTable1.Open are very fast (good) but GetIndexNames returns nothing (bad).

Microsoft Jet OLEDB 4.0 driver

Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=dBASE IV;OLE DB Services=-1;Data Source=c:\mypath

doing operations like ADOTable1.Open are exceedingly slow (bad) while GetIndexNames does return index names the way it should (good).

How do I get both speed and the index info via ADO for the dBase tables?

Microsoft Paradox Driver 7.x

“We use the following connection string which works really well.”

Provider=MSDASQL.1;Persist Security Info=False;Extended Properties="Driver={Microsoft Visual FoxPro Driver};UID=;SourceDB=c:\mypath;SourceType=DBF;Exclusive=No;BackgroundFetch=Yes;Collate=Machine;Null=Yes;Deleted=Yes;"
