Ftp Class

FTP Component [IP*Works! V8]

Properties Methods Events Configuration Settings

The FTP component can be used to transfer files to and from FTP servers using the FTP Protocol.

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The FTP component implements a standard FTP client as specified in RFC 959 and RFC 1579.

The first step in using the component is specifying the RemoteHost, User and Password. The file to upload to or download from is given by the RemoteFile property. The file to download to or upload from is specified by LocalFile. The current path in the server is specified by the RemotePath property. The Passive property is especially useful if the client is behind a firewall which inhibits incoming connections to higher ports.

If LocalFile is set to something other than an empty string, then files are received in LocalFile, otherwise the data is received through the Transfer event. StartTransfer and EndTransfer are fired at the beginning and end of transmission.

The PITrail event traces the interaction between the client and the server (the FTP Protocol Interface connection).

Directory listings are received through the DirList event.
