Hi
Can all fields in a db(specifically ib) be converted to the following
varianttypes.

vtInteger:
vtBoolean:
vtChar:
vtExtended:
vtString:
vtPointer:
vtPChar:
vtObject:
vtClass:
vtWideChar:
vtPWideChar:
vtAnsiString:
vtCurrency:
vtVariant:
vtInterface:
vtWideString:
vtInt64:

Also can fields that gets added like TIBOFloatField also be "casted" to the
above varianttypes. My question is actually how does the tfield type manage
different types of fields and how does the class make sure of compatibility
when you convert a field to a variant.
How will tfield know when a field is TIBOFloatField and not just a
TFloatField?

Thanks
Gerhardus
