function Config(ConfigurationString: String): String;
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
DoAction Method (OfficeEncryptor Component)

Syntax
function DoAction(ActionID: String; ActionParams: String): String;
Remarks
DoAction is a generic method available in every component. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.
The unique identifier (case insensitive) of the action is provided in the ActionID parameter.
ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....
Encrypt Method (OfficeEncryptor Component)
Encrypts the whole document.
Syntax
procedure Encrypt();

Call this method to encrypt the document.
Reset Method (OfficeEncryptor Component)
Resets the component settings.
Syntax
procedure Reset();

Reset is a generic method available in every component.
Error Event (OfficeEncryptor Component)
Information about errors during signing.
Syntax
type TErrorEvent = procedure ( Sender: TObject; ErrorCode: Integer; const Description: String ) of Object;
property OnError: TErrorEvent read FOnError write FOnError;
Remarks
This event is fired in case of exceptional conditions during the office document processing.
ErrorCode contains an error code and Description contains a textual description of the error.
Notification Event (OfficeEncryptor Component)
This event notifies the application about an underlying control flow event.
Syntax
type TNotificationEvent = procedure ( Sender: TObject; const EventID: String; const EventParam: String ) of Object;
property OnNotification: TNotificationEvent read FOnNotification write FOnNotification;
Remarks
The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.
The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.
This component can fire this event with the following EventID values:
DocumentLoaded | Reports the completion of Office document processing by the component. Use the event handler to access document-related information. The EventParam value passed with this EventID is empty. |
SignatureLoaded | Reports the completion of signature loading. When this event fires, you can expect the signatures to be fully loaded. The EventParam value passed with this EventID is empty. |
