There are two ways to disconnect a server using a connection component:

• Set the Connected property to False.
• Call the Close method.

When Connected is set to False, the connection component generates a BeforeDisconnect event, where you can perform any cleanup before the connection closes. For example, you can use this event to cache information about all open datasets before they are closed. 

After the BeforeConnect event, the connection component closes all open datasets and disconnects from the server. 

Finally, the connection component generates an AfterDisconnect event, where you can respond to the change in connection status, such as enabling a Connect button in your user interface.
