I need pass a dinamic array to a COM server (build with VFP 6)

I can pass ok readonly arrays, buit i need grow and write the array(pass by ref) and return back the info to the .NET ASP.NET page (yes, i can use XML but this requiere a LOT of recode, if this can be done in 2-3 hours i don't ask this...)

I do this:

Dim MiArray() as object OR
Dim MiArray(0,7) as Object

' I don't import the COM server because this cause a lot of troubles

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

oSrv.MiMethod(MiArray)

In this line a error occurs(This is the complete stackt trace:)
