Hello

I install in Debian Sarge 3.1 Lazarus 0.9.10, this run very well, but
I install package sqldb, I insert a button in a form and do doble-
click in this and the editor insert the lines from the object. I
insert a pgconnection or mysqlconnection and do doble-click and the
editor make a error from TConstructor not found sqldb or other source
not found.

What is the problem?

The problem seems to be that the TLoginEvent has not been defined yet.
Also a login screen for database is not part of Lazarus or SQLDb. You
can however safely use the SQLdb package.

I think he meant that you can only do the connection at runtime at the
moment, ..... unless someone implements a login form.

No, what I meant is: You cannot use the login-event at the moment. You
can make your own login-form and enter the given information in the
TDatabase.UserName and TDatabase.Password. Something like:
Code: [Select]
  FormLogin := TFormLogin.Create(nil);
  try
    FormLogin.ShomModal;
    with MySQLXXConnection1 do begin
      UserName := FormLogin.Username;
      Password := FormLogin.Password;
    end;
  finally
    FormLogin.Free;
  end;
  MySQLXXConnection1.Open;

FormLogin would be a form with two edits and each edit would fill a
property (UserName and Password) from FormLogin. If you want, I can
make a complete example for this.

You can however connect in Design time as well, you only have to fill
the properties UserName and Password of TDatabase. When you have done
so (and filled host and database), you can set the active property to
true.

The error you have to fix is (according to the IDE  ):
Quote
 Error: identifier not found: TLoginEvent

TLoginEvent is not yet defined in FPC / Lazarus, so you cannot use the
OnLogin-event at this moment.
Double clicking on a component creates a standard event for that
component. The Connection-component has only one event (OnLogin). As I
said the TLoginEvent is not yet defined, so you cannot use it.

I do not know how I can explain it more clearly.
