Don't use the OnCreate event, it can happen before the object it is sent to
has been constructed. Note that the OnShow event can be triggered more than
once.

For an object that needs to persist for the life of a form, create that
object in the form's constructor (and delete it in the destructor). If the
object is needed only for the length of a procedure, it can be created,
used, and deleted in that procedure.
