Use formsweb.cfg to pre-populate database field on login screen?

Question

Hello,
Is it possible to configure formsweb.cfg to pre-populate the 'Database' field on the Oracle forms login screen? I still want users to be able to overwrite what's entered there but just have it populated with something by default.
Thanks,
Andrew

Hi,
In Forms 10g you can set the userid parameter to something like "@DATABASEID LOGON_SCREEN=YES", where databaseid is your database server.
In Forms 11g this doesn't work so well, but I got round this by doing the following in our menu form, if you haven't got a single menu form then you may need to do this in all your forms where the user isn't already logged on when the form opens.
First off you need to set the userid parameter to something like "@DATABASEID".
Next an on-logon trigger is required in your menu or first form, I used the following:
on-logon trigger
DECLARE
cn VARCHAR2(80);
BEGIN
** Get the connection info
** If userid paramater in formsweb.cfg is set to '@<database>' or
** '@<database> login_screen=true' then this will put <database> into database field
** in default logon form
cn := Get_application_property(CONNECT_STRING);
if instr(cn,' ') > 0
then
cn := substr(cn,1,instr(cn,' ')-1);
end if;
LOGON(null,'@'||cn,TRUE);
if form_success
then :global.login_success := 'TRUE';
end if;
END;
Also, to deal with the situation where a user decides to click cancel in the logon screen, you need to put the following at the start of your wnfi trigger.
when-new-forms-instance trigger
default_value('FALSE','global.login_success');
if :global.login_success != 'TRUE'
then
erase('global.login_success');
exit_form;
end if;
erase('global.login_success');
