Remarks
The Exit event applies only to controls on a form, not controls on a report. This event does not apply to check boxes, option buttons, or toggle buttons in an option group. It applies only to the option group itself.
To run a macro or event procedure when this event occurs, set the OnExit property to the name of the macro or to [Event Procedure].
Because the Enter event occurs before the focus moves to a particular control, you can use an Enter macro or event procedure to display instructions; for example, you could use a macro or event procedure to display a small form or message box identifying the type of data the control typically contains, or giving instructions on how to use the control.
The Exit event occurs before the LostFocus event.
Unlike the LostFocus event, the Exit event does not occur when a form loses the focus. For example, suppose you select a check box on a form, and then click a report. The Enter and GotFocus events occur when you select the check box. Only the LostFocus event occurs when you click the report. The Exit event doesn't occur (because the focus is moving to a different window). If you select the check box on the form again to bring it to the foreground, the GotFocus event occurs, but not the Enter event (because the control had the focus when the form was last active). The Exit event occurs only when you click another control on the form.
If you move the focus to a control on a form, and that control doesn't have the focus on that form, the Exit and LostFocus events for the control that does have the focus on the form occur before the Enter and GotFocus events for the control to which you moved.
If you use the mouse to move the focus from a control on a main form to a control on a subform of that form (a control that doesn't already have the focus on the subform), the following events occur:
Exit (for the control on the main form)
ß
LostFocus (for the control on the main form)
ß
Enter (for the subform control)
ß
Exit (for the control on the subform that had the focus)
ß
LostFocus (for the control on the subform that had the focus)
ß
Enter (for the control on the subform to which the focus moved)
ß
GotFocus (for the control on the subform to which the focus moved)
If the control you move to on the subform previously had the focus, neither its Enter event nor its GotFocus event occurs, but the Enter event for the subform control does occur. If you move the focus from a control on a subform to a control on the main form, the Exit and LostFocus events for the control on the subform don't occur, just the Exit event for the subform control and the Enter and GotFocus events for the control on the main form.
참고
You often use the mouse or a key such as TAB to move the focus to another control. This causes mouse or keyboard events to occur in addition to the events discussed in this topic.
