Well I am not sure I completely understand what you are doing.
If you do not have Frontpage open, but open Access, and then ask
Access to open the database by browsing on your computer to the fpdb
folder of your web, and then opening the databse that resides there,
and then making / saving changes that change the structure of the
database (like adding a table), Frontpage will not know that you
changed the database.
If you have Frontpage open, then click on the fpdb folder, then open
the database and edit it (for example to add a table) I really dont
know if Frontpage "knows" what you did to the database. I never do it
that way, so I just dont know, maybe it is ok. Or not.
I get databases into FP one of two ways. The first way is to make a
form, and then save the form results to a database using the Wiz,
which lets you create a new database in the fpdb folder and get a
connection to it.
The second is to make the database in Access and save it somewhere on
my computer, say in My Databases.. Then open FP, open the web of
interest, go to the fpdb folder and then import the database from the
My Databases folder. Again, FP will set up the connection to the copy
of the database that is now in the fpdb folder.
Now, if I need to add a table to the database, I open the database in
the My Databases folder, and add the table to it. Then I open FP and
re-import the database. That way FP understands the changes.
Realize that when you re-import, the database that was in the fpdb
folder gets replaced with the newer version in your My Databases
folder. So you want to make sure the new version contains all the data
the old one does.
Hope this results in you being at least no more confused than me :=)
