StayInSync Property Example (VB)
This example demonstrates how the StayInSync property facilitates accessing rows in a hierarchical Recordset.
The outer loop displays each author's first and last name, state, and identification. The appended Recordset for each row is retrieved from the Fields collection and automatically assigned to rstTitleAuthor by the StayInSync property whenever the parent Recordset moves to a new row. The inner loop displays four fields from each row in the appended recordset.
