CHANGE LICENSES

CHANGE LICENSES

Does not require any parameters

Description​

The CHANGE LICENSES command displays the 4D License Manager dialog box.

This command can only be used with 4D single-user applications and cannot be called from a component. When passwords are enabled, this command can only be executed by the Designer or Administrator; it does nothing when it is called by users that do not have appropriate access rights.

Using the License Manager dialog box, a user can activate plug-ins or the Web server on the machine where it is executed. In 4D, you can display this dialog box by selecting the License Manager... command in the Help menu.

CHANGE LICENSES is a convenient way to activate licenses and add expansion numbers in a compiled single-user 4D application distributed to customers. 4D developers or IS managers can use this command to distribute a 4D application and let users enter their license without sending an update of the application each time.

For more information about this dialog box, refer to the Installation and activation section in the 4D Installation Guide.

Example​

In a custom configuration or preferences dialog box, you include a button whose associated method is:

  // Object method for bLicense button
 CHANGE LICENSES

This way a user can activate licenses without having to modify the database.
