AbsolutePosition and CursorLocation Properties Example (VB)

This example demonstrates how the AbsolutePosition property can track the progress of a loop that enumerates all the records of a Recordset. It uses the CursorLocation property to enable the AbsolutePosition property by setting the cursor to a client cursor.
