How do I prevent from the Login Dialog to be displayed when opening a table, connected to a TSession.
I know how to do it with TDatabase, but the TSession creates a new one on the fly, when the table is opened and I can't access that TDatabase prior table opening.

Hi ronit,

Use AddPassword property :

Session.AddPassword('ASecret');

If no password exists you'll get a dialog.

Now I get the dialog twice. I don't want to see it at all.
This is my code:

Session1.AddPassword('informix');
Session1.open;
Table1.open;

Any other suggestions?

INFORMIX. When we use Far database, before connecting, we get login dialog. I don't want this dialog to be displayed. I want to put the password in the code.

Ronit,

This is what I tried Out -

I dropped a TDatabase component and set its LoginPrompt property to False. In the Params property, I added the following statements-
username='Name Of The User'
password='Password'.

Then I dropped the TSession Component on the form and set the KeepConnections property to true. In the Session property of the TDatabase component, I assigned the newly dropped TSession component name.

By doing this the dialog does not come up at all.

Does this answer your question ?.

Yes, for each TSession you need another TDatabase component.

Ronit,

U can link multiple databases to one TSession component and specifically open each database by using the Session.Opendatabase('DatabaseName') statement.

Bijoy, strange I thought that for multi-threaded applications each tsession needs another tdatabase. Well, if not I learned again something. Great.

I create TSessions on the fly and open Tables via these sessions.
When a Table is opened via a TSession, Automatically a temporary TDatabase is created by that session and a connection is established.

In my case in each new connection, that bothering dialog apears.
To prevent it I need to set The new TDatabase parameters as Bijoy says, but the problem is that I can't access it before the connection, because it is created internaly by the TSession, so what I do is Create my own, prior the Table connection as follows:

begin
  Session1.Open;
  with TDatabase.Create(nil) do
  begin
    LoginPrompt:=False;
    Params.Values['PASSWORD']:='informix';
    Temporary := True;
    DatabaseName:='RRAServer';
    KeepConnection:=Session1.KeepConnections;
    SessionName := Session1.SessionName;
  end;
  Table1.SessionName:=Session1.SessionName;
  Table1.open;//here where the dialog should apear but now it doesn't
end;

There is no need to free the TDatabase, because it was declared as Temporary and will be freed automatically when that session closes.

Thank you all, I don't know who should get the points ZifNab or Bijoy, what do you think?

Sure no, problem. But if Bijoy wants them all, he also may get them (maybe easier).

I don't know how to split the points, So since Bijoy was closer to the answer, then he/she should get the points.
Sorry ZifNab, I'll have to reject your answer.
Bijoy post some extra tips as an answer and you'll get the points.

Hi all,

Same for me Bijoyn, learning and knowing of each other is much more than just earning these points. Have totally no problem with you getting the points, because you really deserve them, besides, heck, why do we need points.

Regards.
c.u. Zif.

Hi every body,
There is no need to be the Pope. This is some kind of Game/Competition, which one loses and the other wins, no big deal. With This points you can then ask your own questions. So?

? Ronit. You can't ask questions with points earned for a correct answer. Or am I wrong? Besides, you're right it makes things a little bit funnier to make a sort of competition of it. But for that we don't have to pull each others hear out ;-)
