Comments

If the connection to an ADS variable is no longer required, it should be closed using the AdsDisconnectEx() method. If only certain specific values are required in a form, the connection should only be created when the form is loaded, and should be released again when the form is closed. See also the AdsReadVarConnectEx() method.
