CRecordSet -->Sort

[Morftje]

Hi all,
How do I get the data out of my Access-Database into my flexgrid, sorted on one of the recordfields, chosen by me?
I can get the data into my flexgrid, but only sorted on the ID-number.
m_...Set.SetCurrentIndex(recordfieldvariable)


gives no error, but a Debug Assertion Failure.
Thanx.

From the on-line help for DAO:

Records returned from a table-type recordset can be ordered only by the indexes defined for the underlying tabledef. To sort records in some other order, you can open a dynaset-type or snapshot-type recordset using an SQL ORDER BY clause stored in CDaoRecordset::m_strSort.

Where can I get more info concerning this subject?

You are not really using CRecordSet are you? SetCurrentIndex is a method of CDaoRecordSet.

Anyway, all you need to do is set up your m_strSort variable before you do an Open() or Requery() for your recordset any the sort should take place. On-line help exists for CDaoRecordSet::m_strSort.

Here is an example:

pConditionsSet->m_strSort = "[ConditionSetID], [Logic]DESC, [FieldID]";

This sorts my recordset in ascending ConditionSetID, descending Logic and ascending FieldID.

After setting the m_strSort variable make your call to Open() or Requery().

Hope this helps.
