I'm looking for a tutorial on how to set-up delphi to access paradox 4.0 tables in a multi-user environment. Using Delphi 6 enterprise on a novel network. I've searched hi and low and can't find any information. Any suggestions would be greatly appreciated! Thanks in advance.

Setting the same path on all machines for the network lock file, and setting Local Share = True are the two "biggies." For more about BDE configuration and setup, follow the links from http://info.borland.com/devsupport/bde/

First off you need to decide how you are going to access the data on the server. The BDE is the most obvious choice using Delphi but there are other alternatives (ADO,Interbase).

Your best bet would be to go to the borland site
Old UBB Archived Link: [URL=http://www.borland.com]www.borland.com[/URL]
and see what best suits your needs. (if you have a small number of users accessing a relatively small database, then Interbase is not for you, but the BDE could be the answer to all of your problems).

Sounds like the BDE setup to me. Check out the BDE administrator in your control panel. Under the configuration tab, check out the drivers/native settings. In here, the Net Dir path needs to be pointing to the same folder on the server on each workstation. If this is not set sorrectly, you will indeed receive .Net warnings as several files will all be trying to manage access to the same database.

Ideally, you should create a new folder on the server specifically for housing the paradox .Net file. This folder should be seperate from your actual database and should be the path to which all workstations Net Dir points to.

Hope this helps you out.

I am using the BDE. I have a small application written. See the thing is, we use paradox 4.0 currently, obviously outdated and in need of revisions. So I'm working on a new application, piece by piece that will allow a greater variety of reports/stats etc. I have this small application up and running. It works on my computer, and it works on another computer..I'm just interested in what is required to get it working on both at the same time. It will be necessary to have aproximately 25 simulataneous users. Now I know that the BDE uses the same .lck and .net files as paradox, but when I try running the applications on two computers at the same time...I get errors.
