Config Method (OfficeDecryptor Component)
Sets or retrieves a configuration setting.
Syntax
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.

Decrypts the whole document.
Syntax
public void Decrypt();
Public Sub Decrypt()
Remarks
Call this method to decrypt the document.
DoAction Method (OfficeDecryptor Component)
Performs an additional action.
Syntax
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;....
Reset Method (OfficeDecryptor Component)
Resets the component settings.
Syntax
public void Reset();
Public Sub Reset()
Remarks
Reset is a generic method available in every component.
DecryptionPasswordNeeded Event (OfficeDecryptor Component)
Request to provide decryption password during decryption.
Syntax
public event OnDecryptionPasswordNeededHandler OnDecryptionPasswordNeeded; public delegate void OnDecryptionPasswordNeededHandler(object sender, OfficeDecryptorDecryptionPasswordNeededEventArgs e); public class OfficeDecryptorDecryptionPasswordNeededEventArgs : EventArgs { public bool CancelDecryption { get; set; } }
Public Event OnDecryptionPasswordNeeded As OnDecryptionPasswordNeededHandler Public Delegate Sub OnDecryptionPasswordNeededHandler(sender As Object, e As OfficeDecryptorDecryptionPasswordNeededEventArgs) Public Class OfficeDecryptorDecryptionPasswordNeededEventArgs Inherits EventArgs Public Property CancelDecryption As Boolean End Class
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
public event OnErrorHandler OnError; public delegate void OnErrorHandler(object sender, OfficeDecryptorErrorEventArgs e); public class OfficeDecryptorErrorEventArgs : EventArgs { public int ErrorCode { get; } public string Description { get; } }
Public Event OnError As OnErrorHandler Public Delegate Sub OnErrorHandler(sender As Object, e As OfficeDecryptorErrorEventArgs) Public Class OfficeDecryptorErrorEventArgs Inherits EventArgs Public ReadOnly Property ErrorCode As Integer Public ReadOnly Property Description As String End Class
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
public event OnNotificationHandler OnNotification; public delegate void OnNotificationHandler(object sender, OfficeDecryptorNotificationEventArgs e); public class OfficeDecryptorNotificationEventArgs : EventArgs { public string EventID { get; } public string EventParam { get; } }
Public Event OnNotification As OnNotificationHandler Public Delegate Sub OnNotificationHandler(sender As Object, e As OfficeDecryptorNotificationEventArgs) Public Class OfficeDecryptorNotificationEventArgs Inherits EventArgs Public ReadOnly Property EventID As String Public ReadOnly Property EventParam As String End Class
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. |
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.OfficeDecryptor Config Settings
