How do I make a Control property an array

I am a bit new at creating ActiveX controls.
I am trying to set up a property for the control I am making as a variable array. However I have been unable to do it. I know there is a way to do it, but I don't know how. Can Anybody point me in the right direction? Some example code would be great.

maybe a collection is even nicer then an array,
and you don' need any tricks for that,
