access another forms controls & properties at runtime

how can you access a control on a form from another form at runtime. For
example to set the datasource and datamember properties of a forms binding
source from a different form?

I am trying to do something like:

form test = new form();
test.show();
test.bindingsource.DataSource = bla bla;

Write the other form so that it exposes properties correctly.

It's a big architectural mistake to go delving into a form and fiddling
with the properties of child controls.
