    SecureFtpServer ActiveX Control

     

    Use the SecureFtpServer control to create FTP server applications which can transfer files using SSL, TLS, or PCT. Features include:

     

    • Use SSL 2.0, SSL 3.0, PCT, TLS or unencrypted FTP communications.
    • Customize certificate acceptance or rejection.
    • Client authentication fully supported.
    • Uniquely capable of SSL over FTP through a Firewall using Dart's proprietary FirewallReady functionality (requires PowerTCP products on both sides of the connection).
    • The SecureFtpServer control uses an internal Daemon object and dynamically creates internal TCP objects as each passive connection is automatically accepted. Use this TCP object to send and receive data to that individual connection.
    • When a request is received, a corresponding event is raised. Write your own custom handling code in the event handler.
    • Add authentication and customized user directories within the Login event.
    • Disallow changing directories within the ChangeDirectoryUp and ChangeWorkingDirectory events to those who do not have proper permissions.
    • Disallow directory creation/deletion within the MakeDirectory and RemoveDirectory methods to those who do not have proper permissions
    • Disallow file upload/download within the Retrieve and Store event to those who do not have proper permissions.

    PowerTCP SSL for ActiveX Features

     

    Daemon ActiveX Control

    Use the Daemon control to build a multi-threaded server. Can accept an unlimited number of connections that can be assigned to dynamic SecureTcp controls for stream management. Features include:

    • Can accept an unlimited number of connections.
    • After accepting a connection, pass it to a Tcp control to send and receive data to the remote host.
    • The Daemon control comes complete with extensive samples demonstrating its use.
    • Help file quick starts show also demonstrate how to use the Daemon control.
    • Controls can operate on separate threads, so Server Applications can be written using apartment model multi-threading features. Or, see PowerTCP Server for ActiveX for an ActiveX control which already does this.

    Interface
    Public Properties
    LocalAddress Returns the address in use while the Daemon is active and an empty string when the Daemon socket is closed.
    LocalPort Returns the port number in use while the Daemon is active and 0 when the Daemon is closed.
    ReuseAddress When True, the REUSEADDR socket option is set to accept duplicate use of the same LocalAddress / LocalPort pair (these are optional parameters of the Connect and Listen methods). If used, this property must be set prior to calling the Connect or Listen method and can be set at design time.
    Timeout Controls the blocking behavior of methods that can be used in blocking and non-blocking ways.
    Public Methods
    About Show the About Box.
    Accept Accept a connection and pass it to a TCP control for subsequent connection management. The Listen method must have been previously used to listen for passive connections.
    Close Release system resources.
    Listen Start listening for passive connections.
    Accept Fires when a passive connection occurs. Use the Accept method to get the socket, then transfer it to a TCP control for management.
    Error Fires when an error condition occurs.

      

    Code Example

    How easy is the Daemon ActiveX control to use? The following VB example demonstrates accepting a connection.

     

    ' Listen for connections on Port 7
    Daemon1.Listen 7

    Private Sub Daemon1_Accept()
    ' create a new TCP Control and assign the Socket to it
    Dim Tcp1 As Tcp

    ' myclass supports event notification for Tcp operation
    Set Tcp1 = New myclass
    Tcp1.Socket = Daemon1.Accept
    End Sub

    NT Service ActiveX Control

     

    The NT Service control is used to turn any application into an NT Service. Features include:

     

    • Easily turn any server applications built using PowerTCP products into services.
    • Applications built with the Service Control target server-side applications that always run in the background, even when a user is not logged into the system.
    • With the Service control you can respond to all service events, including Start, Stop, Pause, and Resume. The Message event is included to support user messages sent from external applications. The Log method is included for logging event messages.
    • Convenient Install and Uninstall methods provide a way for your application to install and uninstall itself as a service. The Abort method allows your service to abort and stop itself while running.

    Connect Connect the service to the operating system’s Service Control Manager (SCM). Call this method as soon as possible after your application starts.
    Install Install the application as a service.
    Log Enter an event in the Windows Event Log.
    Uninstall Uninstall a service.
    Public Events
    Error Fires when an error occurs. This event fires before the error is reported back to the container's error object
    Message Fires when an application sends the service a user message. This can be used any way you wish, as it has no special meaning to the operating system.
    State Fires to indicate the State property has changed value.

     

     

    Code Example

    How easy is the NT Service control to use? Check out the following Service VB example below, which demonstrates creating an echo service with the Server control.

    Message Object

     

    Use the Message object to decode MIME email into an object representation you can easily manipulate. Every attachment, part, and label element is presented as an object, giving you un-surpassed processing control. Performs encoding too, so you can pass messages between the POP, IMAP, and SMTP controls! Features include:

     

    • Detailed knowledge of MIME is not required to use the Message object.
    • The Message object provides an object representation of any email message. This formatting object supports easy manipulation of simple and complex (even nested) MIME messages.
    • Additional features of the MIME object include persistence to disk in two formats: transport ready (encoded) message format and a quick loading (decoded) object format.
    • Encoded/decoded data need not be spooled to disk, making this product a real performer for messages buffered in memory.
    • One method call builds a message.
    • Create a ready-to-send HTML message with a single line of code.
