ADO RecordSet "Update Criteria"

[tashikit]

I've been trying to set the "Update Criteria" of
an ADO RecordSet but have not been successful
in determining the proper syntax.

A VB example is:

rs.Properties("Update Criteria") = adCriteriaKey

The following is the kind of
the syntax i'm using to set other attributes:

m_pADORecordset->put_CursorLocation(adUseClient);

any help would be appreciated...
