Setting Page size on an ado command

I have Borland C++ Builder 6 and I am am trying to run a query against the
active directory.
The problem is that only 1000 records are returned.  The solution is to set
the Page Size property of the Command object
to a larger number, say 64.  This works in VB.

When I try it in C++ Builder, first it gave me a linker error that
CheckAutoResult was not found.
I worked around that problem by adding:

namespace System {
    void __fastcall CheckSafecallResult(HRESULT hr)
    {
        OleCheck(hr);
    }
}

Now when I set the property the error code says that property is not
available.

Here is the code:

        comm->Properties->Item["Page Size"]->Value = 64;   // This line
gives an error saying that Page Size is not in the collection.
        rc->Recordset = comm->Execute();

        while(!rc->Eof){
                ... do something
            rc->Next();
       }

If I take out the Page size setting, the code does work but only retreives
1000 rows (an Active Directory thing).

Can someone help me?

Thanks
Chris
