VaultDelete Event

Fires to delete a callback mode vault.

Syntax

typedef struct {
  String Vault;
  int ResultCode;
} TcbsCBDriveVaultDeleteEventParams;

typedef void __fastcall (__closure *TcbsCBDriveVaultDeleteEvent)(System::TObject* Sender, TcbsCBDriveVaultDeleteEventParams *e);

__property TcbsCBDriveVaultDeleteEvent OnVaultDelete = { read=FOnVaultDelete, write=FOnVaultDelete };

Remarks

This event fires when the component needs to delete the callback mode vault identified by Vault.

This event only needs to be handled if the CallbackMode property is enabled; please refer to the Callback Mode topic for more information. To handle this event properly, applications must delete the vault identified by Vault.

The Vault parameter contains an application-defined vault identifier (name, file path, etc.). The value of this parameter will always match the current value of the VaultFile property.

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.

Note: An application should not attempt to call component's methods from handlers of this event. Doing this is guaranteed to cause a deadlock.

Note: when a storage is opened concurrently in read-only mode by several applications using CBDrive or CBMemDrive component, the event will fire only in the first application. To prevent such a situation, always open a vault in read-write mode.
