I will take a look at it, I think contact actually works on my
machine, but some of the samples don't agree with D2, so I haven't
used many of them.

Okay, one funny question on this, I see that the key is in:

TdmContact.cnContactBeforeConnect however in my case Protocol could
be other then cpLocal (most likely cpTcpIp(?)) I would guess in that
case you don't bother to check for a file exists, you just drive on.

I would probably check who they are logged on as, and if they are not
logged on as SYSDBA, then they get a login prompt, where they need to
type in the SYSDBA password. I don't want it embedded anywhere,
because then they need a new .exe if they ever change it.

Actually that is the trick with the script above, the CREATE DATABASE
statement doesn't count on the SYSDBA password being other then
masterkey, in my case it's different. This could of course be built
on the fly. I don't think right now you can change a username, but
that might change, in future versions. There would need to be logic
somewhere that would allow the username for SYSDBA to be stored
somewhere.

Oh well, I think that's it for now, have a good weekend.....
