It is a separate download - keep going down the Downloads page to the
Documentation section.

You probably haven't found the Getting Started Guide, then...it covers the
connection basics in mind-numbing detail, with pictures...<g>

First, I recommend using TIBODatabase with TIBOQuery, instead of
TIB_Connection and TIB_Transaction. If you need to add more transaction
objects, you can use TIBOTransaction. The "native IBO" components (TIB_*)
that you have used are not incompatible, exactly, but they have less
encapsulation of the TDataset-compatible stuff which TIBO* components were
designed for.

You probably have used some utility to set the Windows environment
variables isc_user and isc_password. This is how it comes about that you
are eventually able to connect despite "failing" the login.

IBO doesn't acknowledge the possibility of password-free login. If you set
the LoginPrompt to false, you must supply the username and password somehow
yourself. You can do this in the relevant properties of the connection
object and you will have to set the PasswordStorage property to psNotSecure
(it defaults to psNone, meaning login with LoginPrompt false is
impossible). Get hold of the help text and read up the doc for
PasswordStorage.

Then supply the username and password in the connection object and set
PasswordStorage to psNotSecure, as above. This compiles these properties
into your application with light encryption on the password; and anyone
can find out how to break into your server by reading your DFM file and
decrypting the password.

Yes, in native IBO you have to open the datasets with run-time code. If
you really do have the Getting Started Guide, there are several code
examples in there. If not, most if not all of the sample apps have them.
