I think in the above code you are confusing class with instance. I presume you have subclasses of EditField, ListBox, etc., defined that implement a Load method. Let's say your classes are named myEditField, myListBox, and myMoviePlayer. Then the code should read: if control(i) isa myEditField then myEditField(control(i)).Load if control(i) isa myListBox then myListBox(control(i)).Load if control(i) isa myMoviePlayer then myMoviePlayer(control(i)).Load Use the class name, not the instance's name (even though they all have the same name, the compiler doesn't know that).
