URGENT: ADO null pointer error on a computer without developer environment


I have a Visual C++ 6.0 program with ADO database access on an oracle 8.0.5-database. On the computer with my development environment anything is o.k. But if I install my programm on a new computer without that environment I get the database connection, but when I do the first SELECT or UPDATE-statement, I get an error:

code: invalid pointer
source: null
description: null

Do I need some DLL´s from my development environment on the computer, and if so, which?

Thanks in advance!!!!

You need to install Microsoft Data Access Components (MDAC).
