The VIRTUAL clause is used so that these methods are defined in the classes that are created inheriting from the principal.

Silvio, where have you copied that code?
In the class where that code was, it is the main class or "parent" class

Silvio, I think I have not explained myself well, or you have not understood my message.
When a method is declared VIRTUAL in a class (in this case TVCard), it is because the programmer will carry out a class (TMyVCard, for example) that will inherit from the initial (TVCard), and in that class the methods that are developed will be developed VIRTUAL declared in the initial class (TVCard).

yes, I had arrived at this.
Then another problem that the tvcard class reads only the first record instead in the file there are so many.
I think it was made just to read only one vcard, in fact it only points to the first interval "BEGIN: VCARD", "END: VCARD"
but how can you make it read the next interval?
Having only one record is not difficult to insert on a dbf but
basically the problem for me is how to read the other records in the vcf file
maybe I will be able to resolve if I can turn the 00001.vcf file into as many vcf as there are records in my phone book.
but how to do this conversion?
