"Joanna Carter [TeamB]" <joanna@not.for.spam> a οΏ½crit dans le message de news: 445ce011$1@newsgroups.borland.com... | "By value" means that, whatever you do to that reference inside the method, | it won't affect the reference passed in. "By reference" means that you can | change the reference inside the method and it will affect the reference | passed that was passed in. Let me just clarify further that when I talk about affecting the reference being passed in, I am talking about changing the memory address of it, not the contents of the object contained in the reference. Both "by value" and "by reference" will allow you to change the contents of the object being passed in and you will still be working with the same object. "By ref" allows you to change the object that the reference passed in is holding, something you don't want to do. Joanna -- Joanna Carter [TeamB] Consultant Software Engineer
