PowerTCP FTP for ActiveX features

 

FTP ActiveX Control

The Ftp control is a powerful and flexible component-based implementation of the FTP protocol. High-level properties and methods provide quick code creation and ease-of use, while access to lower-level properties and methods provide power and control. Here are some feature highlights:

• Select SSL 2.0, SSL 3.0, PCT, TLS or unencrypted FTP communications.
• Login method combines connection setup and authentication into one easy step.
• MGet and MPut methods transfer multiple files, including directory trees, with a single line of code.
• Customize certificate acceptance and rejection; client authentication fully supported.
• The powerful DartStream object permits the transfer of files directly to and from memory.
• Supports both asynchronous (event-driven) and synchronous (scripted) application designs.
• Supports large file transfers, with sizes greater than 4 GB.
• Resumes interrupted transfers, and aborts transfers without losing the session connection.
• Progress event reports data sent and received in real-time.
• Listing object automatically parses listings into easy-to-use objects.
• Performs ASCII or Binary transfers, in both Passive and Active modes.
• Command method sends custom and raw commands to the server.
• Creates and deletes folders on the server.
• Get and Put methods perform complete transfer sessions from a single line of code.
• Trace method provides access to the underlying communication, making logging and debugging sessions easy.
• The Ftp control is NOT dependent on Wininet.dll.
• Transfers files through all common firewalls and proxies, including Socks 4/5, Ftp SITE, Ftp USER, Ftp OPEN, Http CONNECT, and more.
• Can be used in traditional client applications and services, as well as scalable ASP applications.
• Can operate transparently in the background while other tasks are performed, or operate interactively like in most popular FTP applications.

 

Interface

 

Public Properties
Allocate	Indicates whether space must be allocated on a server as part of the Store method.
Authentication	Specifies the security protocol and authentication type used.
Blocked	A True value indicates the control is currently executing a blocking method (Timeout is greater than 0), which has neither completed nor timed out with a ptTimeout error.
Certificate	Certificate Object to use when authenticating to the remote host.
Directory	Working directory on the server.
FileStructure	File structure to be used for subsequent file transfers.
Listing	Object containing results from the last use of the List method or the NameList method.
LocalAddress	When the State property is tcpConnected, LocalAddress returns the address of the local host in dot notation (for example, nnn.nnn.nnn.nnn). When not connected, it returns an empty string.
LocalDataPort	Gets or sets a string used to restrict the local data port to a value or range compatible with your firewall.
LocalPort	When the State property is tcpConnected, LocalPort returns the port number that the socket is bound to. When not connected, it returns 0.
Passive	Indicates how the data connection is formed.
Protocol	Specifies the security protocol used.
ProxyHost	Specifies the name or address of the proxy server that requests are to be routed through.
ProxyPassword	Password to be sent on all requests through a proxy server that requires authentication.
ProxyPort	Specifies the port used by proxy server that requests are to be routed through.
ProxyType	The type of proxy server used for this connection.
ProxyUsername	Username to be sent on all requests through a proxy server that requires authentication.
RemoteAddress	Returns the address of the remote host in dot notation (i.e. nnn.nnn.nnn.nnn) when the State property is tcpConnected.
RemotePort	Returns the port number of the remote host when the State property is tcpConnected.
Restart	Indicates the server supports a restart mechanism for file downloads.
SecretKey	Sets the secret key used in password encryption.
Security	Sets the security level during communication.
State	Provides status information to the user interface. The State event fires to signal that this property has changed.
StoreType	Type of store that will be performed when the Store method is called.
System	Type of operating system used by the server.
Timeout	Controls the blocking behavior of methods that can be used in blocking and non-blocking ways.
TransferMode	Transfer mode to be used for subsequent file transfers.
Type	Data type to be used for subsequent file transfers.
Public Methods
Abort	Abort any blocking method and release all system resources.
AbortCommand	Gracefully abort the last command sent.
About	Show the About Box.
ChangeDirectoryUp	Set the working directory to the parent directory. The Directory property can be checked to discover the new working directory.
ClearCertificate	Clears the Certificate object contained in the Cerificate property.
Command	Send any command string to the server. This method is useful for using servers that have an extended vocabulary.
Delete	Delete a file on the server.
Get	Log in, get a file, and log out in one step.
Help	Request helpful information from the server. The command takes an optional argument (for example, any command name) and returns more specific information as a response.
List	Get a file directory listing. The server sends name and supplementary information on each file found within the specified PathName. The Listing property is populated with this information.
Login	Connect to a server and send the commands to authenticate a session.
Logout	Gracefully log off and terminate the connection.
MakeDirectory	Create a directory.
MGet	Retrieve (get) multiple files or entire directory trees.
MPut	Store (put) multiple files or entire directory trees.
NameList	Get a file directory listing without file attributes. The server sends a file name for each file found within the PathName specified. The Listing property is filled with filenames (only the Name property is initialized).
NoOperation	Check the status of the control connection. The server should send an OK reply.
Put	Login, store a file, and logout in one easy step.
RemoveDirectory	Remove a directory.
Rename	Rename a file.
Retrieve	Retrieve (get) a complete file or part of a file starting at a specified position.
Site	Specify or request site-specific services. The nature of these services and the specification of their syntax can be found in the Result parameter of the Help method.
Status	Get server status information.
Store	Store (send) a complete file, or part of a file starting at a specified position.
StructureMount	Mount a different file system data structure without altering login or accounting information.
Trace	Start or stop the accumulation of trace or debug data. Once started, this method accumulates data until it is turned off.
Public Events
Authenticate	Fires when the remote host has sent a certificate to be authenticated.
Certificate	Fires when the remote host is requesting a certificate and the Certificate property is not set to a valid Certificate Object.
Error	Fires when an error condition occurs.
Progress	Fires when the server replies to a command or while a file transfer takes place. The control interprets the reply and presents progress information with this event.
State	Fires when the State property changes.
