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 insencitive) 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;....

Open Method (ArchiveWriter Component)

Opens an archive file.

Syntax

void __fastcall Open(int ArchiveType, String ArchiveName);

Remarks

Use this method to open an existing archive file for modification.

Provide the path to the archive file via the ArchiveName parameter, and pass the archive type in the ArchiveType parameter.

The following archive types are currently supported:

aftUnknown (0)It was not possible to establish the type of the archive file.
aftZip (1)The archive contains data in ZIP format.
aftGzip (2)The archive file contains data in GZIP format.
aftBzip2 (3)The archive contains BZIP2 data.
aftTar (4)The archive contains a .tar file.
aftTarGzip (5)The archive contains a .tar.gz file.
aftTarBzip2 (6)The archive contains data in .tar.bz2 format.

The archive will be kept in memory until written down with Save or SaveStream method.

OpenBytes Method (ArchiveWriter Component)

Loads an archive file from a byte array.

Syntax

void __fastcall OpenBytes(int ArchiveType, DynamicArray<Byte> ArchiveBytes);

Remarks

Use this method to load an existing archive file from a byte array.

Provide the archive stream via the ArchiveBytes parameter, and pass the archive type in the ArchiveType parameter.

The following archive types are currently supported:

aftUnknown (0)It was not possible to establish the type of the archive.
aftZip (1)The archive contains data in ZIP format.
aftGzip (2)The archive file contains data in GZIP format.
aftBzip2 (3)The archive contains BZIP2 data.

Remove Method (ArchiveWriter Component)

Removes file(s) and/or folder(s) from the archive.

Syntax

void __fastcall Remove(String Path);

Remarks

Use this method to remove entries from the archive. Provide an archive-local path via the Path parameter.

Path supports file masks, which makes this method quite powerful (and potentially dangerous).

Save Method (ArchiveWriter Component)

Compresses the archive and saves it to a file.

Syntax

void __fastcall Save(String ArchiveName);

Remarks

Use this method to finalize all preparations, compress all the entries set up in Files collection, and write the created archive to ArchiveName file.

This method carries out a lot of work and fires a number of events during its execution. Before the compression process starts, PrepareFile event fires repeatedly to provide the summary of what is being included into the archive. A handler of that event is a good place to make last-minute modifications to the data sources, file names, and actions to take upon the files.

Compression of each entry is surrounded with BeforeCompressFile and AfterCompressFile "brackets". Subscribe to BeforeCompressFile to supply the file contents for entries with Buffer and Stream data sources. AfterCompressFile is a good place to release the content stream alloated in the BeforeCompressFile event handler.

Progress event fires repeatedly to report the progress of the current and whole operations. It also provides an opportunity to abort the compression process.

SaveBytes Method (ArchiveWriter Component)

Compresses the archive and saves it to a byte array.

Syntax

DynamicArray<Byte> __fastcall SaveBytes();

Remarks

Use this method to finalize all preparations and compress all entries contained in the Files collection. The method returns the byte array containing the serialized archive.

You can fine-tune the compression process by providing compression details on the fly via the events component fires. See the description of the Save method for the details.

UpdateFile Method (ArchiveWriter Component)

Updates an existing compressed entry with a fresher local version.

Syntax

void __fastcall UpdateFile(String Path, String LocalPath);

Remarks

Call this method to update the Path entry in the archive with a fresher entry at LocalPath.

UpdateFiles Method (ArchiveWriter Component)

Updates a selection of files in the archive.

Syntax

void __fastcall UpdateFiles(String Folder, String LocalPath, bool AddMissingFiles, bool RemoveMissingFiles, bool Recursive);

Remarks

This method is a powerful way to update a subset of files in the archive in accordance with a specified criteria.

Pass an archive-local name of the folder to update via the Folder parameter, and the system-local version of the same folder via the LocalPath parameter. Set AddMissingFiles and RemoveMissingFiles as needed to force inclusion of files missing from the archive, or removal of files missing locally, accordingly.

The Recursive parameter specifies whether the directory should be browsed recursively.

UpdateVirtual Method (ArchiveWriter Component)

Updates an entry in the archive with on-the-fly content.

Syntax

void __fastcall UpdateVirtual(String Path);

Remarks

Use this method to update content of an existing archive entry. Pass the archive-local entry path via the Path parameter. After updating the entry, tune up its DataSource property in accordance with the desired content origin. Subscribe to BeforeCompressFile to supply the actual data via FileData or FileStream properties.

AfterCompressFile Event (ArchiveWriter Component)

Marks the completion of compression of a file.

Syntax

typedef struct {
  String Path;
  __int64 FileSize;
  int DataSource;
} TsbxArchiveWriterAfterCompressFileEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterAfterCompressFileEvent)(System::TObject* Sender, TsbxArchiveWriterAfterCompressFileEventParams *e);
__property TsbxArchiveWriterAfterCompressFileEvent OnAfterCompressFile = { read=FOnAfterCompressFile, write=FOnAfterCompressFile };

Remarks

Subscribe to this event to get notified about the completion of compression of a file.

The Path parameter specifies the internal path to the entry inside the archive. The FileSize indicates the size of the file before compression, and the DataSource specifies the type of the source media.

fdsFile (0)The data was taken from a file.
fdsStream (1)The data was taken from a stream assigned to FileStream property.

  int DataSource;
} TsbxArchiveWriterBeforeCompressFileEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterBeforeCompressFileEvent)(System::TObject* Sender, TsbxArchiveWriterBeforeCompressFileEventParams *e);
__property TsbxArchiveWriterBeforeCompressFileEvent OnBeforeCompressFile = { read=FOnBeforeCompressFile, write=FOnBeforeCompressFile };

Remarks

Subscribe to this event to be notified about the start of compression of an archive entry. The handler of this event is a good place to prepare the desired data source.

The Path parameter indicates the path to the extracted entry in the archive. The FileSize specifies the size of the file before compression. Use this event handler to adjust the data source if the file is to be loaded from a stream or buffer. The DataSource parameter indicates the type of the data media:

fdsFile (0)The data will be taken from a file indicated by the entry's LocalPath setting. You can change this path in the handler of this event.
fdsStream (1)The file data will be taken from a stream assigned to FileStream property.
fdsBuffer (2)The data will be taken from a buffer attached to the FileData property.
If passing the data from a stream or buffer, use AfterCompressFile to dispose of any objects allocated in this event handler (such as the source stream).

Use PrepareFile event to adjust the file data source on the fly.

DecryptionPasswordNeeded Event (ArchiveWriter Component)

Fires when the component needs a password to decrypt the archive.

Syntax

typedef struct {
  String PasswordTarget;
  bool Cancel;
} TsbxArchiveWriterDecryptionPasswordNeededEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterDecryptionPasswordNeededEvent)(System::TObject* Sender, TsbxArchiveWriterDecryptionPasswordNeededEventParams *e);
__property TsbxArchiveWriterDecryptionPasswordNeededEvent OnDecryptionPasswordNeeded = { read=FOnDecryptionPasswordNeeded, write=FOnDecryptionPasswordNeeded };

Remarks

Component fires this event to request a decryption password from the application when it comes across an encrypted archive or entry.

Please assign the password to DecryptionPassword property inside the event handler, or set Cancel to true to cancel the operation.

Error Event (ArchiveWriter Component)

Reports information about errors during archive assembling.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TsbxArchiveWriterErrorEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterErrorEvent)(System::TObject* Sender, TsbxArchiveWriterErrorEventParams *e);
__property TsbxArchiveWriterErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The event is fired in case of exceptional conditions during archive formation.

ErrorCode contains an error code and Description contains a textual description of the error.

Notification Event (ArchiveWriter Component)

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

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxArchiveWriterNotificationEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterNotificationEvent)(System::TObject* Sender, TsbxArchiveWriterNotificationEventParams *e);
__property TsbxArchiveWriterNotificationEvent 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 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.

PrepareFile Event (ArchiveWriter Component)

Fires for every file to be compressed before the compression starts.

Syntax

typedef struct {
  String Path;
  __int64 FileSize;
  int DataSource;
  String LocalPath;
  int Action;
} TsbxArchiveWriterPrepareFileEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterPrepareFileEvent)(System::TObject* Sender, TsbxArchiveWriterPrepareFileEventParams *e);
__property TsbxArchiveWriterPrepareFileEvent OnPrepareFile = { read=FOnPrepareFile, write=FOnPrepareFile };

Remarks

Component fires this event for every file included in the Files collection before commencing the compression. This is the last opportunity for your code to adjust the action to be taken for each file and tune up the data sources appropriately.

The Path parameter contains the path to the file within the archive (such as Photos/myphoto.jpg), and the FileSize contains the size of that file before compression.

The DataSource parameter indicates the media from which the file contents is to be taken. A typical default value if fdsFile, but you can adjust the value of that parameter if you need to use an alternative source. The following options are available:

fdsFile (0)The data will be taken from a file indicated by the LocalPath parameter. You can change this path in this event handler.
fdsStream (1)The file data will be taken from a stream assigned to FileStream property.
fdsBuffer (2)The data will be taken from a buffer attached to the FileData property.
Please do not assign FileStream or FileData in this event handler: this should be done further down the road in the BeforeCompressFile event handler. The purpose of this event is to prepare the compression plan by summarizing what should be done and to which files.

The Action parameter, which is also tuneable, indicates the action for component to take on the file:

atAdd (0)Add the file to the archive
atKeep (1)Keep the existing file in the archive
atUpdate (2)Update the archived file with a fresher copy
atDelete (3)Delete the file from the archive
atExtract (4)Extract the file (extraction only)
atSkip (5)Skip file extraction (extraction only)

Progress Event (ArchiveWriter Component)

Reports the progress of data compression.

Syntax

typedef struct {
  __int64 Processed;
  __int64 Total;
  __int64 OverallProcessed;
  __int64 OverallTotal;
  bool Cancel;
} TsbxArchiveWriterProgressEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterProgressEvent)(System::TObject* Sender, TsbxArchiveWriterProgressEventParams *e);
__property TsbxArchiveWriterProgressEvent OnProgress = { read=FOnProgress, write=FOnProgress };

Remarks

Subscribe to this event to be notified about compression progress.

Processed and Total report the progress of compression of the current entry; OverallProcessed and OverallTotal report the progress of the whole operation. Set Cancel to true to stop the operation.

RecipientFound Event (ArchiveWriter Component)

Signifies that the archive was found to be encrypted with a digital certificate.

Syntax

typedef struct {
  DynamicArray PublicKeyHash;
  bool CertFound;
} TsbxArchiveWriterRecipientFoundEventParams;
typedef void __fastcall (__closure *TsbxArchiveWriterRecipientFoundEvent)(System::TObject* Sender, TsbxArchiveWriterRecipientFoundEventParams *e);
__property TsbxArchiveWriterRecipientFoundEvent OnRecipientFound = { read=FOnRecipientFound, write=FOnRecipientFound };

Remarks

The component fires this event to notify the application that the archive was found to be encrypted with a digital certificate. The hash of the certificate's public key is provided in the PublicKeyHash parameter.

CertFound indicates whether a certificate with a matching public key hash was found in the DecryptionCertificates list. If it wasn't, you need to locate it on the system and add it to that list: component won't be able to decrypt the archive otherwise.

Please note that the certificate must have an associated private key to be capable of decryption.

Config Settings (ArchiveWriter 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.

ArchiveWriter Config Settings

MaxASN1BufferLength:   Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth:   Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm:   Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the component. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

StaticIPAddress[domain]:   Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the component) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses:   Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

TLSSessionGroup:   Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the components.

TLSSessionLifetime:   Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval:   Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

UseOwnDNSResolver:   Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages:   Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemOAEPAndPSS:   Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom:   Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

Trappable Errors (ArchiveWriter Component)
