SYMPTOMS
The Microsoft Foundation Classes (MFC) documentation for CDaoRecordset::AddNew and the DAO SDK documentation for the AddNew method state: <pre class="fixed_text">  "The position of the record depends on the type of Recordset:    - In a dynaset-type Recordset object, records are inserted at the end   of the recordset, regardless of any sorting or ordering rules that may   have been in effect when the recordset was opened." The documentation is incorrect. Beginning with Jet 3.0, this behavior is not guaranteed. The behavior was changed to improve performance as well as concurrency issues.

To demonstrate the change in behavior, delete a record in a recordset of 300+ records and then call AddNew. Then, traverse the recordset until you see where the record has been added. Typically, this record will be inserted in the 253rd record rather than at the end of the recordset.

<div class="status_section">

STATUS
This problem was corrected in the documentation for Visual C++, version 6.0.

MORE INFORMATION
If the goal is to make the newly added record the current record, you should get the bookmark of the last modified record and move to that bookmark. You can do this with MFC DAO by doing the following: rs.SetBookmark(rs.GetLastModifiedBookmark);

Additional query words: AddNew MoveLast
