Unmount Event

Fires after the component unmounts media from the virtual drive, making it unavailable.

Syntax

type TUnmountEvent = procedure (
  Sender: TObject;
  var ResultCode: Integer
) of Object;

property OnUnmount: TUnmountEvent read FOnUnmount write FOnUnmount;

Remarks

This event fires once the component has unmounted media from the virtual drive, making it unavailable. Please refer to UnmountMedia and DeleteStorage for more information.

This event is optional; it is provided to give applications a chance to perform additional processing when the virtual filesystem becomes unavailable.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
