How to know 'opened forms'

Question

hi
On main form, I am accessing other forms through my own customized menu. But there is no control to check whether form is already open or not. whenever i click menu, another instance of form is created. How to control this. I guess there should be some control in menus for it ?
or how to control that, at a time, one instance of form should be opened through menu?
best regards

You can refine this code even further by making it a procedure and the it can check for any form name. The procedure is as follows:
PROCEDURE check_open_form(form_name VARCHAR2) IS
frm_id formmodule;
BEGIN
frm_id := FIND_FORM(form_name);
IF NOT ID_NULL (frm_id) THEN
MESSAGE('Form '| |form_name| |' is already opened');
go_form(frm_id);
ELSE
OPEN_FORM(frm_id, ACTIVATE, SESSION);
END IF
END;
You can then call any form using this procedure in say a button item using When-Button-Pressed trigger. Issue a call to the procedure to call form named "slap" like:
check_open_form('slap');
