How do i pass a referenced variant into a OLE method? I am not able to
create a Variant object as reference and pass into invoke method. Does
anybody knows how? In the class, Variant, they have a constructor that allow
you to create it by pointer and type.

new Variant(ptr, OLE.VT_BSTR | OLE.VT_BYREF);

Such Variant will hold the pointer of the value, one can use setByRef() to
change the value using this reference.

This is similar to what I am looking for, but instead of creating a variant
reference to the safearray, I need it to point to the integer value. I can't
figure how to alloc the memory and point it back from the variant reference.

Thanks,

Michael
