when you call JetUpdate (), the third arg is a bookmark. After JetUpdate () completes, you can search for the bookmark with

Note that you can also get the auto-increment value before by calling JetUpdate, since this value is assigned when JetUpdate is called. You need to use the JET_bitRetrieveCopy parameter with JetRetrieveColumn.

For an example in managed code, see "How to get the value of a column with auto-increment"? section on this page .
