SUMMARY
=======
To create unique filenames based on individual workstation operators, each
user's identification (ID) must be obtained from the environment. Third-party
API libraries that can interface with the network to provide this information
are available; however, you can also use a batch file to capture the user IDs
during interactive logins if only medium security is required.
MORE INFORMATION
================
To capture a user ID, you must create a batch file with the same name as the
command normally executed to log in. For example, if the normal method is to
type LOGIN followed by an ID, the batch file would be named LOGIN.BAT.
To create the file:
1. In a text editor, create a new file with the appropriate name.
2. Within the new file, type the following:
SET USER=%1
CD NET
LOGIN %1
3. Save the file in the root directory.
The next time the machine completes startup, LOGIN and the user ID are typed in
as normal, but at subsequent logins, the LOGIN.BAT file will intercept the user
ID and assign the ID (passed as the first parameter on the command line, [%1])
to the MS-DOS environment variable USER and then pass it to the original LOGIN
program in the NET subdirectory.
If the network LOGIN file is found through the MS-DOS PATH statement, place
LOGIN.BAT in the root directory so that it will be executed first. However, if
the AUTOEXEC.BAT selects the subdirectory where the original LOGIN program is
found, you need to modify AUTOEXEC.BAT to find LOGIN.BAT first. For added
security, you can mark the LOGIN.BAT file as Hidden with the MS-DOS ATTRIB
command.
Once the login is finished and FoxPro is running, the ID can be retrieved with
the GETENV() function. The following commands demonstrate its usage:
usrname=GETENV("USER")
The variable usrname contains the user ID.
