As I said before I don't think so: I have those vars as well and the
command line tools (and the BDE - a little known feature) use it.
Nothing else is documented to use those vars, including the services
API. Since it goes as expected and documented on my system, it's you
who needs to figure out why it works differently for you. I don't have
any additional clue. :-(

This is a Firebird message. For whatever reason fbembed thinks it's
homeless. You could try to alter some default in firebird.conf to see
whether it just can't find aliases.conf or that applies to
firebird.conf as well. I suspect it won't find firebird.conf as well,
or firebird.conf points to a different home dir. That's about all that
comes to mind. I have fbembed deployed on hundreds of systems and
growing with no such problems.

H> Huh, I don't get that point.

That's a pity. Try to read between the lines, my english writing can
either be quick or clear, not both at the same time. ;-)

Does the developer also know that when he puts a database name in the
edit box and clicks the Connect menu item the program connects to a
hardcoded database name specified in the dfm instead? If so I must be
a dumber-than-average developer, because I had to look at the code to
find out. :-)

H> Duh. Why?

Well, at least tell the user something when the backup is finished,
possibly telling also what's the backup file name to look for, since
it's random!

H> Anyway, thanks for testing the blank username/password thing.

You're welcome.
