The ArchiveReader component supports inspection and extraction of files from zip, tar, gzip and bzip2 archives.

Syntax

TsbxArchiveReader

Remarks

ArchiveReader offers capabilities of inspecting, editing, and unpacking archived files from a variety of archive formats. ArchiveReader archiveReader = new ArchiveReader(); archiveReader.setDecryptionPassword("MyPassword"); // the decryption password for the archive // Opens the archive file, first param is the archive type and the second one the path of the archive archiveReader.open(ArchiveReader.aftZip,"C:/MyArchives/folder.zip"); // extract all the files to the path provided archiveReader.extractAll("C:/Extracted/extractedFolder");

The following common archive formats are supported:

• ZIP (.zip)
• GZip (.gz)
• BZip2 (.bz2)
• Tar+GZip (.tar.gz)
• Tar+Bzip2 (.tar.bz2)

Working with ArchiveReader

Work with ArchiveReader builds on the following steps:

Opening the archive.

On this step the component loads the provided compressed data into its memory. You can pass the compressed data as a byte array (OpenBytes), as a stream (OpenStream), or load it from a disk file (Open).

Inspecting the archive contents

Use the Files collection to access information about individual files stored in the opened archive. On this stage you can adjust the individual files objects' > and > properties to configure bespoke processing for specific files.

Extracting the files

Call ExtractAll to initiate extraction of all the files contained in the archive and selected using the > property, or Extract to extract a single file. The component notifies your code about each individual extraction using its BeforeExtractFile and AfterExtractFile events. You can use BeforeExtractFile to provide your final decision about the extraction of a particular file.

Use DecryptionPassword property to specify a decryption password for an archive and/or a specific entry within it. If the password is required but wasn't set, or if the provided password is wrong, the component will fire the DecryptionPasswordNeeded event. This event is fired repeatedly until the correct password is provided or its Cancel parameter is returned as true.

Closing the archive

Once you are finished with the archive, call the component's Close method to close the archive file and release the associated memory.

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

Data Type

String

SigningCertSubject Property (ArchiveReader Component)

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name.

Syntax

__property String SigningCertSubject = { read=FSigningCertSubject };

Default Value

""

Remarks

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via SigningCertSubjectRDN.

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

Data Type

String

SigningCertSubjectKeyID Property (ArchiveReader Component)

Contains a unique identifier of the certificate's cryptographic key.

Syntax

__property DynamicArray SigningCertSubjectKeyID = { read=FSigningCertSubjectKeyID };

Remarks

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The SigningCertSubjectKeyID and SigningCertCAKeyID properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

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

Data Type

Byte Array

SigningCertSubjectRDN Property (ArchiveReader Component)

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Syntax

__property String SigningCertSubjectRDN = { read=FSigningCertSubjectRDN };

Default Value

""

Remarks

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.

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

Use this method to close the archive that is currently opened and release the associated memory. You won't be able to extract files or access the archive details after closing the archive.

Config Method (ArchiveReader 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.

DoAction Method (ArchiveReader Component)

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;....

Extract Method (ArchiveReader Component)

Extracts a single file from the archive.

Syntax

void __fastcall Extract(String Path, String LocalPath, bool PreserveFullPath);

Remarks

Use this method to extract a single file from the archive.

Pass the internal path to the entry in the archive via the Path parameter, and the path where to save the extracted entry via the LocalPath parameter. Set PreserveFullPath to true to enforce full-path extraction, in which case LocalPath would indicate the mount point at which the full Path needs to be rooted. If PreserveFullPath is false, the LocalPath provides the final location for the extracted file.

Use ExtractAll to extract all files at once.

ExtractAll Method (ArchiveReader Component)

Extract all the files contained in the archive.

Syntax

void __fastcall ExtractAll(String OutputPath);

Remarks

Use this method to extract all the files contained in the archive file. Pass the path where the extracted files should be saved via the OutputPath parameter.

You can cherry-pick the files to extract, as well as choose different extraction destinations (including files at custom locations, streams, or memory buffers) by subscribing to BeforeExtractFile and AfterExtractFile events.

Use Extract to extract a single file.
