How can I extract data from another client?

I want to read data from an application open on antoher client. How can I do this?

Forgot to mention that I'm sitting on a WAN of NT machines.

How is it 'open on another client'? Is it sitting on the local hard disk?

You would have to set up a share on that disk. I do not know of any other way of direct access to a local hard disk. This can be secured using the standard NT tools, but it would be easier to have it on a shared disk.

Or maybe, you mean an Access db opened exclusively? Get them to open it shared and then connect read-only.

Just some ideas,

Paul.

I don't think I was clear enough. It's actually an excel file running on another client. The file is not saved regularly, but the data in the file is updated very often. I want to get this data. Initially I put an almost 'sniffer'-like application on the client and had it export the data as a text file, but it wasn't a good solution. It stole processor power from the client. Anyway, does anyone know how to solve my problem?

Can you help me, please. I'm dying.
