This can easily be done by using a common table and exchange data by that table, but that

OK, you’ve said what you want to do. Can you explain what you’re actually trying to accomplish? And what do you mean by sending a “message”?

That’s easy: I want to protect my database from using in another environment, so I want to let a sort of dongle run on the networkserver: a computer only I have access to. The application runs on several machines in the factory. Whenever a user logges on, the application sends a message to the server-application, containing username and user-computer-ID. The server identifies the user and user-machine. The user-application will only continue if idenfication is valid. When failed, the user-application will not run.
The user-application is protected, so users can’t debug my applicaiton, but making a copy and using it at home, or selling it to others can always be done. This way I want to prevent them from successfully doing that!

As far as I know, without lots of complicated code at the Windows API level, you can’t do what you describe. However, it would be fairly simple to look for a table that is an attached table stored on the network server, and if it isn’t found, shut the application down. As long as your application is protected with compiled code (an MDE) and has appropriate security, that should protect your application from would-be poachers.
