[V4RB] RAM-based databases

Thanks for your reply, Ruslan.

Yes, that was my problem with the *example* database, as I reported on
Mantis. My question here was more general, and was not related to the
server question. (It's another puzzlement, though: why do you have
supply a project which is supposed to be a good example of how to do a
RAM-based database BY DEFAULT create the database on the server
machine instead? That doesn't seem like a good example! But anyway,
that's not the issue here.)

So, just to be consistent, you require that a RAM-based database be
"opened" even after you've created an instance of it, and that you
pass as its opening parameters a folderitem, the number of files you
want the database to use, and even the segment size for the files?

OK, that's valid then -- though I'd be interested to know why you'd
want to define different numbers of logical files in a RAM-based db.

But it just doesn't seem like Valentina's style to require me to pass
bogus parameters just for the sake of consistency.

> Work with RAM db differ only in constant kRamDb instead of kDiskDb

OK, I've got it. And as of a few hours ago I have both the example and
my own project working fine. I just wanted to confirm that I'm really
doing this the right way.

Thanks again,
