AddNew crashing

[nss]

I have

	while (!m_db1.m_pRecordset->GetadoEOF ())
	{


		int n = m_db3.m_pRecordset->RecordCount;
		
		m_db3.m_pRecordset->AddNew();

                SomeStuffThatAddsAValidRecordToDb3();

                m_db1.m_pRecordset->MoveNext();
         }

The first time through, when there were zero records in m_db3, there is no problem. Then it advances m_db1 by 1, and gets back to the top of the while. This time when it tries to execute AddNew it crashes. Incidentally, if I move the AddNew() out (just as a test), then it chokes on both UpDate(), or UpdateBatch(). What am I doing wrong? Thanks very much ns

[nss]

I tracked it to:

inline HRESULT Recordset15::AddNew ( const _variant_t & FieldList, const _variant_t & Values ) {
    HRESULT _hr = raw_AddNew(FieldList, Values);
    if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
    return _hr;
}

but the odd thing is I'm using it like AddNew() with no arguments. It compiles fine .Suggestions? If I did make a fieldlist and a values variable what are these? Arrays? thanks, ns
