Stored procedures
Transfers a file or directory to an FTP server (File Transfer Protocol).
Reports and Queries
// Transfer the "C:\MyDocuments\File.DOC" file
// into the "/Temp" directory on the FTP server
ResSend = FTPSend(ConnectionNum, "C:\MyDocuments\File.DOC", "/Temp")
<Result> = FTPSend(<Connection identifier> , <File/Directory to Transfer> , <Destination file/directory> [, <WLanguage procedure> [, <Transfer mode>]])
<Result>: Boolean
  • True if the transfer was performed,
  • False otherwise. The status report of error is returned by ErrorInfo.
<Connection identifier>: Integer
Connection identifier, returned by FTPConnect.
<File/Directory to Transfer>: Character string
Name and full (or relative) path of the file (or directory) to transfer. A UNC path can be used. No wildcard character can be used (* or?).
If this parameter corresponds to a directory, all the files found in this directory are transferred. A directory with the same name is created on the FTP server at the location specified by <Destination File/Directory>.
If this parameter corresponds to a file:
  • If <Destination File/Directory> is a directory found on the FTP server, the file to retrieve is copied into the destination directory.
  • If <Destination File/Directory> is a file found on the FTP server, the file to transfer is copied and renamed.
<Destination file/directory>: Character string (with quotes)
Name and full (or relative) path of destination file (or directory). This file (or directory) is found on the FTP server. The different path sections are separated by "slashes" ("/").
A full path has the following format: "/<DirectoryName>/<FileName>". The tree structure has the following format: "/<DirectoryName>/<FileName>".
A relative path has the following format: "<DirectoryName>/<FileName>". The tree structure has the following format: "/<CurrentServerDirectory>/<DirectoryName>/<FileName>".
<WLanguage procedure>: Procedure name
Name of procedure automatically called to check the transfer progress.
<Transfer mode>: Optional Integer constant
Transfer mode used:
(Default value)
Transfer performed in binary mode: The file is strictly identical between the sending and the receiving.
ftpASCIIModeTransfer performed in ASCII mode. This mode is used to transfer data between two different types of operating systems, from UNIX to Windows for example: the transferred file is changed into the ASCII format of destination system.

Managing the progress of the transfer

FTPSend is a locking function: no other action can be performed until the end of current transfer. To check the progress of the transfer, FTPSend can automatically call the <Procedure name> procedure at regular intervals.
This procedure is declared as follows:
PROCEDURE <Procedure name>(<Total size>, <Transferred size>)
  • <Total size> is an integer corresponding to the total size of file or directory currently transferred.
  • <Transferred size> is an integer corresponding to the number of bytes already transferred.
For example, you can:
  • display a progress bar,
  • find out whether the transfer is completed (<Total size> = <Transferred size>).
FTPSend cannot be interrupted as long as all files have not been transferred. To force the interruption of the browse, use the following code line in the <Procedure name> procedure:
In any other case (to continue the browse), <Procedure name> MUST return True.
An error is generated if no value (neither True nor False) is returned by the <Procedure name> procedure.

Transfer timeout

By default, all the FTP functions fail if the FTP server does not respond within 20 seconds. This timeout can be modified with FTPConnect when connecting to the FTP server.
Reports and Queries

Internet browser

FTPSend requires Internet Explorer version 3 or later.
If a problem occurs, we recommend that you run a test with the browser by directly passing a link such as "ftp://server/...". If a problem occurs with Internet Explorer (with a UNIX server for example), use FTPCommand directly.

Rights of users

Only a user who has write rights on the FTP server can send files to an FTP server. In most cases, no write rights are granted to the "anonymous" users.

Relative and absolute path

The notions of relative path and absolute path are very important in an FTP application.
  • A path starting with a slash is considered as being an absolute path: it is the path in relation to the root of the FTP server (parameter specific to the server).
    ex: /ad/user/JULIA
  • A path not starting with a slash is considered as being a relative path, which means a path given in relation to the current directory. This current directory can be returned or modified by FTPCurrentDir.
When connecting to an FTP site, the initial directory (the "home directory" of the user) is not necessarily found at the root of the FTP server. Therefore, we recommend that you use relative paths.
