What's the difference between deleting the last element and setting the length to zero? > I knew that an Array isn't a TComponent descendant but what struck > me as strange is that CodeInsight shows I can do this: > MyArrayofTComponents[0].Create() That's taking the first element of the array, which is a value of type TComponent, and calling the Create method on that component.

You get an exception for the same reason you'd get an exception here: var x: TComponent; begin x.Create(nil); end; -- Rob _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
