GET SERIAL INFORMATION
GET SERIAL INFORMATION
The GET SERIAL INFORMATION command returns various information about the 4D current version serialization.
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.
