[2.0] MDI child call parent variable/object

[cc96ai]

Can MDI child call back parent variable or any object?
e.g.
- frmParent
-Public String conn = "abc.mdb";

- frmChild
- Public String test = "demo";

- frmChildTest
- how can we frmParent.conn ?
- and can we call frmChild.test , too ?

the issue i would like to call parent variable,
It would like to create the database connection in parent ,
so each child only need to call parent connection, and dont need to recreate on each form
