Checking to see if Valentina database is open RunRev

[-= JB =-]

I need to read the whole thing again and I am not really working
on that now but it was done using a number of functions which
looked at the list ( I forget the proper function and name).  But it
takes a few of the functions from what I understood.

Are you able to look at the database list and see which ones are
on there.  If you close a database that is open it will show on the
list as being closed and if it is open it will show it is open.

The problem I was having is if I tried to open a database that is
open it would crash.  So I think you need to get the name of the
file and then check the list to see if it is already open.  I know it
is more complicated than that so you need to study the function
that provides you with the list of databases and then use a few
other things to actually get the proper name and check the list.

I am kind of sick right now due to being poisoned in my home
by a secret society here in America who are protected by many
corrupt politicians and corrupt news media hiding that & other
crimes I have been exposing so it is difficult to program.  This
has been reported to the FBI, news media and many others &
the news in America are taking a payofff to hide the crimes.  It
included treason, conspiracy and many other things.

If I was not sick I would restudy it and do it.  Someday I will write
it if someone else does not provide an example.
