In ActiveX, you need to use a SAFEARRAY for that.  Look at the
SafeArray...() function in the API, or the various wrapper classes in the
VCL's safearry.h header file.

If you want your ActiveX control to be accessible to scripting environments
(Javascript, VBScript, etc), then you will have to put that SAFEARRAY inside
of a VARIANT.
