int Save(const QString& qsArchiveName);

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.

virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);

class ArchiveWriterErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(ArchiveWriterErrorEventParams *e);

// Or, subclass ArchiveWriter and override this emitter function.
virtual int FireError(ArchiveWriterErrorEventParams *e) {...}

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 Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireNotification(ArchiveWriterNotificationEventParams *e);

typedef struct {
  const char *EventID;
  const char *EventParam;
  int reserved;
} ArchiveWriterNotificationEventParams;


Unicode (Windows)
virtual INT FireNotification(ArchiveWriterNotificationEventParams *e);

typedef struct {
  LPCWSTR EventID;
  LPCWSTR EventParam;
  INT reserved;
} ArchiveWriterNotificationEventParams;

#define EID_ARCHIVEWRITER_NOTIFICATION 5

virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);

class ArchiveWriterNotificationEventParams {
public:
  const QString &EventID();

  const QString &EventParam();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Notification(ArchiveWriterNotificationEventParams *e);

// Or, subclass ArchiveWriter and override this emitter function.
virtual int FireNotification(ArchiveWriterNotificationEventParams *e) {...}

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. 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 class, the exact action it is performing, or the document being processed, one or both may be omitted.

PrepareFile Event (ArchiveWriter Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FirePrepareFile(ArchiveWriterPrepareFileEventParams *e);

typedef struct {
  const char *Path;
  int64 FileSize;
  int DataSource;
  char *LocalPath;
  int Action;
  int reserved;
} ArchiveWriterPrepareFileEventParams;


Unicode (Windows)
virtual INT FirePrepareFile(ArchiveWriterPrepareFileEventParams *e);

typedef struct {
  LPCWSTR Path;
  LONG64 FileSize;
  INT DataSource;
  LPWSTR LocalPath;
  INT Action;
  INT reserved;
} ArchiveWriterPrepareFileEventParams;

#define EID_ARCHIVEWRITER_PREPAREFILE 6

virtual INT SECUREBLACKBOX_CALL FirePrepareFile(LPSTR &lpszPath, LONG64 &lFileSize, INT &iDataSource, LPSTR &lpszLocalPath, INT &iAction);

class ArchiveWriterPrepareFileEventParams {
public:
  const QString &Path();

  qint64 FileSize();

  int DataSource();
  void SetDataSource(int iDataSource);

  const QString &LocalPath();
  void SetLocalPath(const QString &qsLocalPath);

  int Action();
  void SetAction(int iAction);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void PrepareFile(ArchiveWriterPrepareFileEventParams *e);

// Or, subclass ArchiveWriter and override this emitter function.
virtual int FirePrepareFile(ArchiveWriterPrepareFileEventParams *e) {...}

Remarks

Class 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:

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

Progress Event (ArchiveWriter Class)

Reports the progress of data compression.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireProgress(ArchiveWriterProgressEventParams *e);

typedef struct {
  int64 Processed;
  int64 Total;
  int64 OverallProcessed;
  int64 OverallTotal;
  int Cancel;
  int reserved;
} ArchiveWriterProgressEventParams;


Unicode (Windows)
virtual INT FireProgress(ArchiveWriterProgressEventParams *e);

typedef struct {
  LONG64 Processed;
  LONG64 Total;
  LONG64 OverallProcessed;
  LONG64 OverallTotal;
  BOOL Cancel;
  INT reserved;
} ArchiveWriterProgressEventParams;

#define EID_ARCHIVEWRITER_PROGRESS 7

virtual INT SECUREBLACKBOX_CALL FireProgress(LONG64 &lProcessed, LONG64 &lTotal, LONG64 &lOverallProcessed, LONG64 &lOverallTotal, BOOL &bCancel);

class ArchiveWriterProgressEventParams {
public:
  qint64 Processed();

  qint64 Total();

  qint64 OverallProcessed();

  qint64 OverallTotal();

  bool Cancel();
  void SetCancel(bool bCancel);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Progress(ArchiveWriterProgressEventParams *e);

// Or, subclass ArchiveWriter and override this emitter function.
virtual int FireProgress(ArchiveWriterProgressEventParams *e) {...}

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 Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireRecipientFound(ArchiveWriterRecipientFoundEventParams *e);

typedef struct {
  const char *PublicKeyHash;
  int lenPublicKeyHash;
  int CertFound;
  int reserved;
} ArchiveWriterRecipientFoundEventParams;


Unicode (Windows)
virtual INT FireRecipientFound(ArchiveWriterRecipientFoundEventParams *e);

typedef struct {
  LPCSTR PublicKeyHash;
  INT lenPublicKeyHash;
  BOOL CertFound;
  INT reserved;
} ArchiveWriterRecipientFoundEventParams;

#define EID_ARCHIVEWRITER_RECIPIENTFOUND 8

virtual INT SECUREBLACKBOX_CALL FireRecipientFound(LPSTR &lpPublicKeyHash, INT &lenPublicKeyHash, BOOL &bCertFound);

class ArchiveWriterRecipientFoundEventParams {
public:
  const QByteArray &PublicKeyHash();

  bool CertFound();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void RecipientFound(ArchiveWriterRecipientFoundEventParams *e);

// Or, subclass ArchiveWriter and override this emitter function.
virtual int FireRecipientFound(ArchiveWriterRecipientFoundEventParams *e) {...}

Remarks

The class 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: class 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.

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

Remarks

The ArchiveWriter class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the ArchiveWriter class an instance of that concrete class.

When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

bool CanRead() { return true; }

bool CanSeek() { return true; }

bool CanWrite() { return true; }

int64 GetLength() = 0;

void Close() {}

int Flush() { return 0; }

int Read(void* buffer, int count) = 0;

int64 Seek(int64 offset, int seekOrigin) = 0;

int Write(const void* buffer, int count) = 0;

Trappable Errors (ArchiveWriter Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
