The Deactivate event occurs when a form or report loses the focus to a Table, Query, Form, Report, Macro, or Module window, or to the Database window.
When you switch between two open forms, the Deactivate event occurs for the form being switched from, and the Activate event occurs for the form being switched to. If the forms contain no visible, enabled controls, the LostFocus event occurs for the first form before the Deactivate event, and the GotFocus event occurs for the second form after the Activate event.
When you first open a form, the following events occur in this order:
Open ▐ Load ▐ Resize ▐ Activate ▐ Current
When you close a form, the following events occur in this order:
Unload ▐ Deactivate ▐ Close
