Dynamically create screens in form application

Question

Hi,
I am trying to create a project that will read some
information from a database and then according to what it's ready
will create a number of activities.
I was hoping to making each of these activities as a
different screen that has the activity class attached to them, but
I can't seem to find a way to dynamically create a screen that has
a class name other than the default.
can anyone help me??
thanks

Here is the code which i want to execute on the form so it may better help Forms Gurus....
Again describing the goal, actually I want to fetch the employee record from different users residing in the same database with all the same name and fields , In the Main User, where this form will be exceuted, it fetched records from the employee table from other users dynamically.
PROCEDURE EMPLOyee IS
     DATE_FROM DATE     := EMP_D_from;
     DATE_TO     DATE     := EMP_D_to;
CURSOR C1 IS                                         
SELECT      EMP_NO , EMP_DATE
FROM EMPLOYEE A -- THIS EMPLOYEE TABLE RESIDE IN SOME OTHER USER
WHERE TRUNC(A.EMP_DATE) BETWEEN DATE_FROM AND DATE_TO
AND NOT EXISTS (SELECT B.EMP_NO FROM EMPLOYEE B
WHERE A.EMP_NO = B.EMP_NO);
BEGIN
FOR REC IN C1 LOOP
INSERT INTO EMPLOYEE
(EMP_NO , EMP_DATE )
VALUES
(REC.EMP_NO , REC.EMP_DATE );
INSERT INTO EMP_DET
EMP_NO , S_NO, EMP_DEPT )
SELECT EMP_NO , S_NO, EMP_DEPT
FROM EMP_DET -- THIS SAL_RFT_DET RESIDES IN SOME OTHER USER
WHERE A.EMP_NO = REC.EMP_NO;
END LOOP;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
MESSAGE (SQLERRM);
MESSAGE (SQLERRM);
END;
