Shutting Down Objects

ActiveX objects must shut down in the following way:

• If the object's application is visible, the object should shut down only in response to an explicit user command (for example, clicking Exit on the File menu) or the equivalent command from an ActiveX client.
• If the object's application is not visible, the object should shut down only when the last external reference is gone.
• If the object's application is visible and is controlled by an ActiveX client, it should become invisible when the user shuts it down (for example, clicking Exit on the File menu). This behavior allows the controller to continue to control the object. The controller should shut down only when the last external reference to the object has disappeared.
