Default Value

false

Remarks

This property is reserved for future use.

Data Type

Boolean

InputBytes Property (OfficeDecryptor Component)

Use this property to pass the input to component in byte array form.

Syntax

__property DynamicArray InputBytes = { read=FInputBytes, write=FSetInputBytes };

Remarks

Assign a byte array containing the data to be processed to this property.

This property is not available at design time.

Data Type

Byte Array

InputFile Property (OfficeDecryptor Component)

The Office file to be decrypted.

Syntax

__property String InputFile = { read=FInputFile, write=FSetInputFile };

Default Value

""

Remarks

Provide the path to the Office document to be decrypted.

String

OutputBytes Property (OfficeDecryptor Component)

Use this property to read the output the component object has produced.

Syntax

__property DynamicArray OutputBytes = { read=FOutputBytes };

Remarks

Read the contents of this property after the operation has completed to read the produced output. This property will only be set if the OutputFile and OutputStream properties had not been assigned.

This property is read-only and not available at design time.

Data Type

Byte Array

OutputFile Property (OfficeDecryptor Component)

Defines where to save the decrypted document.

Syntax

__property String OutputFile = { read=FOutputFile, write=FSetOutputFile };

Default Value

""

Remarks

Specifies the path where the decrypted Office document should be saved.

Data Type

String

Password Property (OfficeDecryptor Component)

The password used for decryption.

Syntax

__property String Password = { read=FPassword, write=FSetPassword };

Default Value

""

Remarks

Use this property to provide the decryption password.

Data Type

String

Config Method (OfficeDecryptor Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

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.

Decrypt Method (OfficeDecryptor Component)

Decrypts the whole document.

Syntax

void __fastcall Decrypt();

Remarks

Call this method to decrypt the document.

DoAction Method (OfficeDecryptor Component)

Performs an additional action.

Syntax

String __fastcall DoAction(String ActionID, String ActionParams);

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;....

DecryptionPasswordNeeded Event (OfficeDecryptor Component)

Request to provide decryption password during decryption.

Syntax

typedef struct {
  bool CancelDecryption;
} TsbxOfficeDecryptorDecryptionPasswordNeededEventParams;
typedef void __fastcall (__closure *TsbxOfficeDecryptorDecryptionPasswordNeededEvent)(System::TObject* Sender, TsbxOfficeDecryptorDecryptionPasswordNeededEventParams *e);
__property TsbxOfficeDecryptorDecryptionPasswordNeededEvent OnDecryptionPasswordNeeded = { read=FOnDecryptionPasswordNeeded, write=FOnDecryptionPasswordNeeded };

Remarks

This event is fired when the component needs decryption password from the user.

if CancelDecryption property is set to true value (default value) then decryption would fail if provided password is invalid. Otherwise this event would be fired again.

Error Event (OfficeDecryptor Component)

Information about errors during signing.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TsbxOfficeDecryptorErrorEventParams;
typedef void __fastcall (__closure *TsbxOfficeDecryptorErrorEvent)(System::TObject* Sender, TsbxOfficeDecryptorErrorEventParams *e);
__property TsbxOfficeDecryptorErrorEvent OnError = { 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 (OfficeDecryptor Component)

This event notifies the application about an underlying control flow event.

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxOfficeDecryptorNotificationEventParams;
typedef void __fastcall (__closure *TsbxOfficeDecryptorNotificationEvent)(System::TObject* Sender, TsbxOfficeDecryptorNotificationEventParams *e);
__property TsbxOfficeDecryptorNotificationEvent OnNotification = { 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:

Config Settings (OfficeDecryptor Component)

The component accepts one or more of the following configuration settings. Configuration 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.
