Have you tried storing an object reference in a property of COM comonent?

e.g.
Dim MiArray() as object OR
Dim MiArray(0,7) as Object

oSrv=Interaction.CreateObject("GyGServidorOle.clsConexion")

oSrv.oArray = MiArray
oSrv.MiMethod(MiArray)

You can use oArray in your method instead of passing it as a para?
