Thanks Todd, but I tried that and the the problem isn't so much working out if I've got an array (I know I have at that stage), but how to pass it on without having to pull it apart. The method that receives the data looks abit like this:
procedure MyClass.ReceiveData(const Sender: IUnknown; Params: OleVariant); and I need to send the params (a variant array) to a method declared like this: function OtherClass.ProcessData(const Sender : IUnknown; const Params: array of const); It's the "array of const" declaration that doesn't seem to have a corresponding type that can be passed to it. The only way that I can do it is by pulling apart the OleVariant and passing them, as a hard coded array, to the other method. That's no good because it requires knowledge of what elements are in the array before passing them on. I may need to revisit the architecture.
