The Is license available command lets you find out the availability of a plug-in. It is useful, for instance, for displaying or hiding functions requiring the presence of a plug-in.
The Is license available command can be used in three different ways:
- The license parameter is omitted: in this case, the command returns False if the 4D application is in demonstration mode.
- You pass one of the constants of the “Is License Available” theme in the license parameter:
Constant Type Value 4D Client SOAP license Longint 808465465 4D Client Web license Longint 808465209 4D Draw license Longint 808464694 4D for ADO license Longint 808465714 4D for MySQL license Longint 808465712 4D for OCI license Longint 808465208 4D for PostgreSQL license Longint 808465713 4D for Sybase license Longint 808465715 4D Mobile license Longint 808464439 4D Mobile Test license Longint 808465719 4D ODBC Pro license Longint 808464946 4D SOAP license Longint 808465464 4D View license Longint 808465207 4D Web license Longint 808464945 4D Write license Longint 808464697 In this case, the command returns True if the corresponding plug-in has a license available. The command takes into account any licenses attributed in Design mode or via the SET PLUGIN ACCESS command.
Is license available returns False if the plug-in is operating in demo mode. - You pass the ID number of the plug-in “4BNX” resource directly in the license parameter. In this case, the command behaves as described above.
