Can someone please tell me what I've done wrong here.  I try to pass the
recordset object to the called routine, and in the called routine, I get
pointer fault when I try to access the record set properties or methods

I know it's just my error

Thanks

Caller:
//  Fills a RecordSet with data

#include "main.h"

   TCOM_Connection cn = CoConnection::Create();
    cn->ConnectionString = WideString("DSN=localserver").Detach();
    cn->CursorLocation = Adodb_tlb::adUseClient;
    cn->Open(0,0,0,0);
    WideString sql = "SELECT Title FROM response ";
    TCOM_Recordset rs = CoRecordset::Create();
    rs->Open(sql.Detach(), (IDispatch *)cn, Adodb_tlb::adOpenDynamic,
Adodb_tlb::adLockOptimistic, 0);
    TStatsCalculator *myCalculator = new TStatsCalculator();
    Edit4->Text = FloatToStr(myCalculator->sMean(rs));

}
