The GET SERIAL INFORMATION command returns various information about the 4D current version serialization.
- key: unique ID of the installed product. A unique number is associated to a 4D application (such as 4D Server, 4D in local mode, 4D Desktop, etc.) installed on a machine. This number is encrypted, of course.
- user: Name application user as defined when installing.
- company: User’s company or organization name as defined during installation.
- connected: Number of connected users when executing the command.
- maxUsers: Maximal number of users concurrently connected.
Note: The last two parameters always return 1 for 4D single user except in demonstration versions (0 is then returned).
GET SERIAL INFORMATION is part of the general component protection scheme implemented in 4D. Component developers can associate a copy of their product to a given installed 4D application, in order to avoid any illegal copies.
The serialization works as follows: a user who wants to get a component sends his unique key generated through the GET SERIAL INFORMATION command to the developer. This can be done through an Order form included in a demo version of the component. The generated key is unique and is associated to a specific 4D application.
The component developer can then generate his own serial number combining the key and a given cipher. The delivered component will offer a function verifying if the information returned by the GET SERIAL INFORMATION matches this serial number. Otherwise, the user will not be able to use the component.
Note: Plug-ins developers can use this protection scheme too. For more information, refer to the 4D Plugin API Reference.
