Please I have multiple Modules each with multiple data blocks.

Please on the click of a button, i want to call a new form and

to go to a particular datablock but not the first data block in

the module.

Please is this possible.

Cheers

Warning: this comes from memory, I've got no Forms installed.

1. In the calling Form, use the NEW_FORM built-in in the WHEN-BUTTON-PRESSED trigger of your push-button.

2. In the called Form, use the WHEN-NEW-FORM-INSTANCE trigger, use the GO_BLOCK trigger.

GO_BLOCK trigger


Just correcting a typo.

GO_BLOCK is a Built-in function not a trigger.

Thanks for the post
please this is the scenerio.

i have a module with two data block.

when the form compiles it loads the first block which is the

splash screen , ater 5 seconds it loads the second block which

is the login screen, but if the loggin fails, I want to reload that same data block but without reloading the whole form, because i tried it and it start from the splash canvas again and i dont want that.

Can you post that code where you are validating the login.

thanks here is the code.

this code is attached to the loggin button on the login module, which contains the splash canvas and the login datablock

declare
user_id varchar2(20);
pass varchar2(20);
u_level varchar2(20);

cursor u_login is
select username, passwords, userlevel from userlogin where username=:u_name and passwords=:p_word;

begin
open u_login;
loop
fetch u_login into user_id, pass, u_level;
if u_login%notfound
then
message('Username or Password Invalid Please try again!');
call_form('J:\My Music\My Playlists\New Folder\LOGIN');
elsif u_level ='admin' then
call_form('J:\My Music\My Playlists\New Folder\ADMIN');
else
call_form('J:\My Music\My Playlists\New Folder\USER');
end if;
end loop;
end;

I'd say: use Oracle's REAL user authentication. If the login fails, you stay where you are. If the login passes, you can evaluate the USER and direct him to the correct screen. One application owner, several application users. It makes auditing and access control a lot easier IMO.

But in your case, the form containing the code, is it the J:\My Music\My Playlists\New Folder\LOGIN' form? If so, don't call it again but use a RAISE FORM_TRIGGER_FAILURE (not sure about it's exact name) and the processing will stop.

Yes I tried raising the form trigger error, fine the page did not reload and I want a pop up to come up and say user name or password incorrect, but it is just showing at the bottom of the form.

and when it does that, it does not clear the password and username, but after logging fails can i still remain on that page and then clear the username and password fields.

cheers

Do it in two parts. Get the user logged in and THEN worry about which form to call. Don't mix the two together.

Search this forum for 'login'. This problem has been solved previously. Also search for 'logon_screen' and 'Get_Connect_Info'.
