delphi idftp控件用法（Delphi idftp控件用法）

Delphi idftp control usage 2011-04-25 22:22FTP is a standard

protocol that is the easiest way to exchange files between a

computer and a network.

FTP is also an application protocol standard for applying

TCP/IP protocol.

FTP usually in the file upload to the server, a commonly used

way or from the server file transfer as a user, you can use FTP

with a very simple DOS interface, can also be provided by the

use of third party software (such as FLASHFXP) to the data

server to delete, rename and other operations.

Of course, before using these, you have to log on to the server

and log in with the specified username and password or

Anonymous.

You know, but let's just talk about it. Using DOS to operate

FTP, I'm not talking. Today I'm using IDFTP controls in INDY

components to make a FTP client software (very simple)

I'm going to talk about some of the properties of the IDFTP

control:

Host:FTP server address.

USER: user account number.

Password: password.

Passive: method for controlling FTP data connection. FTP data

transmission can be active and passive.

PORT is active mode, when the data channel is established, the

server to connect to others;

PASV is passive mode. When the data channel is set up, the server

is connected to others;

When establishing data channel, PORT mode or PASV mode, the

right of choice lies in the FTP client.

The passive in IDFTP is a Boolean data type. When True is active;

when false is passive.

The default port for Port:FTP service is 21.

The type of TransferType: transport file can be valued as

FtBinary (8 bit arbitrary file) and FtAscii (7 bit text file).

Description of SystemDesc:FTP server.

Several methods of IDFTP

The commonly used methods are as follows:

Connect: connects to the FTP server

Abort: stops the operation of FTP services.

Quit: closes the connection between the client and the server
