The UserManager class stores information about user accounts.

Syntax

UserManager

Remarks

The purpose of UserManager is storing, importing, and exporting information about users of some service. It is primarily used alongside server and SAML components to manage user account information - for example, to load it from a file or other media.

You start working with UserManager in one of two ways:

• By creating a new user database using CreateNew method.
• By importing an existing user database with ImportFromFile (or ImportBytes) method.

Having loaded or created a user database, you can access the user list via Users list. Use the properties of individual elements of this collection to access the details of a particular user.

Use AddUser method to add blank user accounts to the user list. Use the returned index to locate the user object in the Users list and adjust the settings as required.

If you made changes to the user list, use ExportToFile (or ExportBytes) method to save the updated user database.

Data Type

SecureBlackboxUserAccount

AddUser Method (UserManager Class)

Creates a new user account and adds it to the Users list.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int AddUser(const char* lpszUsername);

Unicode (Windows)
INT AddUser(LPCWSTR lpszUsername);

int secureblackbox_usermanager_adduser(void* lpObj, const char* lpszUsername);

int AddUser(const QString& qsUsername);

Remarks

Use this method to create a new user record.

Error Handling (C++)

This method returns an Integer value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Config Method (UserManager Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* secureblackbox_usermanager_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CreateNew Method (UserManager Class)

Creates a new user account database.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CreateNew();

Unicode (Windows)

int CreateNew();

Remarks

Use this method to create a new user database. The method empties the Users collection and makes the component ready for editing the new database.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

DoAction Method (UserManager Class)

Performs an additional action.

Syntax

• C++
• C
• Qt

char* secureblackbox_usermanager_doaction(void* lpObj, const char* lpszActionID, const char* lpszActionParams);

QString DoAction(const QString& qsActionID, const QString& qsActionParams);

Remarks

DoAction is a generic method available in every class. 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;....

Common ActionIDs:

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

Remarks

Use this method to save the settings of all users to a byte array.

Use a non-empty Password to protect the database.

Error Handling (C++)

This method returns a Byte Array value (with length lpSize); after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

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.

UserAccount Type

A container for user account information.

Syntax

SecureBlackboxUserAccount (declared in secureblackbox.h)

Remarks

UserAccount objects are used to store user account information, such as logins and passwords.

Fields

Constructors

UserAccount()

SecureBlackboxList Type

Syntax

SecureBlackboxList<T> (declared in secureblackbox.h)

Remarks

SecureBlackboxList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the UserManager class.

int GetCount() {}

int SetCount(int count) {}

T* Set(int index, T* value) {}

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

The UserManager 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 UserManager 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;
