The child form to activate.

If the form parameter is already the active MDI child form, then the ActivateMdiChild method simply returns. If form is not a null reference (Nothing in Visual Basic), then it is set to be the active MDI child form.

Whether the form parameter is a null reference (Nothing in Visual Basic) or not, ActivateMdiChild raises the MdiChildActivate event.
