Hi Lionel,

Hi,

Would you mind if I included the developer's mailing list in CC in our
discussion?


Of course not. :)

   I'm working on a new feature in Base again. It's just a little
user helper feature to make available the direct import of an csv
file into table, without open Calc and copy&paste the content from
it to Base.

Base can already do that without resorting to Calc:

1) Menu File / New / Database

2) Connect to existing database / Text

3) Fill in needed configuration

3) Open the just created .odb file in window 1

4) Open the destination .odb file in window 2

5) Drag'n drop (or copy/paste) from window 1 to window 2.

And it works for any supported database type, not only CSV, as long as
the destination database driver supports SDBCX (that is, table
creation).

If you intend to put an easier / faster / ... UI on this procedure,
sure, that seems nice.


 The usability of this method is the same as which I mentioned. Have to
open an other window and use copy&paste (additionally make a useless file).
So yes, my primary aim is to add an easier way.


already have the plan to implement it and it seems to me that it
will work not just with csv files but all Calc compatible format (in
this case only the first sheet will be imported, but later it can be
extended).

This starts to look like you want to reimplement a different way to
achieve the same as the above, and not only slap a different / better
UI on it. Unless there is a good reason (which one?), I'd rather
not. Two implementations = more code, two sets of bugs, confusion for
the user, ...

Note that the above works "for any calc compatible format" by using
"Spreadsheet" instead of "Text". And many other sources...

Again, slapping a better UI on it, that would e.g. avoid the need to
create an .odb file which the user will delete right after, would be
nice. I imagine it would work like this: reuse the database wizard
open existing database and "connect to existing database" stuff to
setup a SDBC URL, but do *not* create a .odb file connecting to that
URL. Instead, connect to that URL in code, list the tables, ask the
user which tables to import, and import them into the current
database. Bonus points for reusing the same codepath as a paste in the
the copy/paste case (one time for each table).


I didn't know about this feature up to now, but for the first blush it is
not the same feature, at least from the users point of view. As I see these
connection is a readonly access to a bunch of csv/text files (or sheets of
one spreadsheet file) with openning an alone database to them. The feature
which I intend to implement is making a new table and insert into the
already opened database. With this I just say that for the user it can be
looked as a different thing and so not make confusion.
(It's really an readonly access? Because copy&paste all the tables not a
usefull method to make them modifyable.)

Implementation is an other part. Of course I will look up the code of this
connection thing and reuse all the usefull code. But the implementation
which I planed is not means real new code, but intentse use of UNO API. The
Writer OLE-object feature use the XEmbeddedObject and other class linked
with it. One advantage of using this XEmbeddedObject is that it uses
implicitly the same file import as Calc do. So in case of csv/text files
the Calc's csv import dialog will be opened, which more usefull than the
page with the same aim in Base. More usefull means more options and a table
showing the expected result.

I don't know the underlying code of this connection feature yet, but I
would not suprise if it uses the same XEmbeddedObject.


I will use up the code which lies under the OLE-object feature of
Writer, which already contains the csv import.

Why would that be any better than what I outlined above?


Because of the mentioned csv import dialog.


   The only question is where this feature would be reachable. I have two
ideas and I think all of these two places should be used:
   1. Table view -> "Tasks". Add a 4th option like "Import Table From
File...". This point contains all other places which are almost the
duplicates of this "Tables" list (e.g. Insert menu with label "Table
(Import)..." ).
   2. Table view -> "Tables" -> context menu. The label can be "Import
Table...".

The context menu does not make that much sense to me, unless we *also*
add the other tasks to it (and then also in Queries, Forms and Reports).


It comes in my mind just because the commonly used method is the copy&paste
and so people get to use the context menu. :)
But of course the first point will be enough too.


Best Regards,
Tamás
