On the Attain Installation Disk, you can install the ODBC Driver. Then create a system or user DSN. The documentation for it is on the installation disk menu. Be sure you read through it, as Navision did a poor job of keeping up with ANSI SQL standards. Thier SQL calls have some syntactical neuances that you have to pay attention to.

I think what u want to know is how to connect to a Navision DB through VB?
You can connect to a Navision DB through VB by using CFront.
You can find the relevant code in the CFront pdf manual.
Just go through the same and if u have any doubts do send me a mail.
