FTPAttribute (Function)

In french: FTPAttribut

Identifies the attributes of a file found on an FTP server (File Transfer Protocol).

Example

See additional examples

// Find out the attributes of
// "/Documents/File.Doc" found on the FTP server
ResAttributes = FTPAttribute(ConnectionNum, "/Documents/File.Doc")

Syntax

Identifying the attributes of last consulted file Hide the details

<Result> = FTPAttribute()

<Result>: Character string

"ERR" if an error occurred. To find out the name of the error, use the function ErrorInfo with the constant errMessage.
One or more letters corresponding to the file attributes ("AH" for example). The following letters are used:
R: Read-only file. The file can be accessed in read-only.
H: Hidden file. The file name is grayed or invisible in the explorer.
S: System file. The file is a Windows system file.
To: "Archive" file. This attribute indicates that the file can be archived. Some programs are using this attribute to find out which files have been saved.
D: Directory or subdirectory. The file is a directory or a sub-directory.
C: Compressed file (on the NTFS partitions). This file was automatically compressed during its copy on an NTFS partition (Windows NT or 2000).
This syntax returns the attributes of the last file accessed by one of the following FTP functions: FTPDate, FTPTime, FTPSize, FTPListFile. Unlike the syntax 2, no request is sent to the server. This syntax is recommended.

Identifying the attributes of specified file Hide the details

<Result> = FTPAttribute(<Connection identifier> , <File name>)

<Result>: Character string

"ERR" if an error occurred. To get the details of the error, use ErrorInfo with the errMessage constant
One or more letters corresponding to the file attributes ("AH" for example). The following letters are used:
R: Read-only file. The file can be accessed in read-only.
H: Hidden file. The file name is grayed or invisible in the explorer.
S: System file. The file is a Windows system file.
To: "Archive" file. This attribute indicates that the file can be archived. Some programs are using this attribute to find out which files have been saved.
D: Directory or subdirectory. The file is a directory or a sub-directory.
C: Compressed file (on the NTFS partitions). This file was automatically compressed during its copy on an NTFS partition (Windows NT or 2000).

<Connection identifier>: Integer

Connection identifier, returned by FTPConnect.

<File name>: Character string (with quotes)

Name and full (or relative) path of file to use. The different path sections are separated by "slashes" ("/").

Remarks

Identifying the files attributes

To retrieve the different attributes of a file, check whether one of the letters identifying an attribute is found in <Result>. This search can be performed by Position for example.

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.

Internet browser

FTPAttribute 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 read rights on the FTP server can identify the attributes of the files or directories found on an FTP server. In most cases, read rights are granted to the "anonymous" users, giving them the ability to identify the attributes of a file or directory found on an FTP server.

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.
