That is the mechanism I use to pass it in. I use the AfterAssignment of the
TIB_ConnectionSource component to assign the connection it got to all the
datasets on that form. This way, when dealing with the form, I just set that
property once and then it takes care of the rest by itself. It is my way of
simplifying cross-for dependencies.
