Note that it has nothing to do with C++ or D++ or even E++!
In ANY virtual table, system needs to know the exact number of rows!
Then system asks rows to show on the table window.
It asks using *index numbers* so your exit module should supply rows
of that index! If your database table has that index number or row 
identifier
as primary key or as index, then you can easily fetch rows on demand.

Otherwise, whether you use virtual or not, if you have to cache all inside
your system, you may be better off with standard tables.
