use paramlist between 2 forms

[gharbi]

I have 2 forms A, B. Form A call form B. I use paramlist in Form A to pass a parameter in form B (OK). My problem is how to receive the paramlist in the form B.

AFAIK, just create the desired parameters in the second form. So, if you need PARAM1 as char and PARAM2 as NUMBER, just create them in the Object navigator, in the node labeled "Parameters"

Suppose we have two forms dept and emp where in dept is the calling form and emp is the called form so we write the following code in dept form on the button

declare
list_Id ParamList;
begin
list_id := get_parameter_list('input_params');
if not id_null(list_id) then
destroy_parameter_list(list_id);
end if;
list_id := create_parameter_list('input_params');
add_parameter(list_id,'d',TEXT_PARAMETER,:deptno);
open_form('emp.fmx',ACTIVATE,NO_SESSION,NO_SHARE_LIBRARY_DATA,list_id);
end;

And now in the called form i.e. emp
in when-new-form-instance write
execute_query;

and the pre-query trigger of the block

deptn0 := :parameter.d;

where in this d parameter has to be created in the called form i.e. emp.

Hope this helps u.

My suggestion is to declare global variables. You can initiate the global variables in form A, use the values in B and set the variable to the new values in B and use it A. You can use DEFAULT_VALUE builtin and PRE- AND POST-FORM triggers for this purpose.
