Computer Identification

[Larry Coleman]

Hello everyone.

In a multi-user system I want to be able to identify the user
who has locked a file for update for an unreasonable amount of
time. What I need to do is use the computer name acquired by
getting it using the "GetComputerName" function in the win32api.

I am assuming that in Microsoft networks this will be a unique
name. This assumption may be a mistake! If Windows is used
under other networking software is this name of any value?
If not, is there a way to obtain the station ID for Novell or
others.

I have searched the Novell web site for information about this
without success. I have also searched this site with no success.
May be my search keys?

If anyone can answer my question or point me in the right
direction it would be appreciated.

I hope this is not a controversial question.

Thanks,
Larry

Larry, this seems similar to the question I recently posted about
obtaining lock info.

How do you plan to determine which workstation has set the lock?

I did this in DOS by very simple way. Because only my program could lock data set, I wrote own log on server and when guy A could not access data during x sec, I read log and informed A that data set is busy by guy B.

Bern,

I currently have what I call a flag file that tracks all files
or records that are locked for update, add or delete. What I am
doing now is generating a unique ID for each station that
uses the system based on the time the system is started. This
works fine but if a problem occurs, such as a user opening a
record for update and going to lunch, the system knows the record
is locked and reports the status correctly to the requesting
user program. Using this method the second user does not know
which station has the file locked. I would like to be able to
tell the user who is locked out that "Mary's" (or whatever name
is used) computer has exclusive access to record. This way
something could be done before Mary gets back without having to
check every computer on the network.

The checking for adds and delete are no problem since locking
and unlocking these are done at system speed. Only an action
such as lightning strikes or power failures should affect these.

Semen,

I am basically doing what you suggest. The only question is can
I acquire a unique ID without having the user logon to my system
in addition to their normal logon?

Thanks to both,
Larry

GetComputerName + GetUserName ?

Larry,

GetComputerName + IP# will work as well. Just store it as a 32
bit number.

My MRP manufacturer uses a similar method, they create a .SEM file
and store the user login name and mac address...

Larry,

I once used something called 'WhoHasIt' (shareware), and a search on Google turned
this up : http://statsware.ackind.net/whohasit/index.html . There was also a link
to a similar-sounding but free utility on the Novell site at
http://www.novell.com/coolsolutions/Assets/Whohasd.exe .

If by any chance your issue is to do with a Jet (Access) mdb file, there's a free
download from Microsoft called JetUtils.exe, which contains a small, non-ActiveX
dll that does what you want.

HTH

Bern,

HTH you too ! I missed your question on this subject.

Cheers -

Paul

Have you tried the "SET" command to list the environment variables
then parse the information you need?

That would be the OSes "SET" command.

NT Resource kit and Win98 come wiht a tool called NetView, it shows you all this info already, pretty slick too....
