New start behaviour

Using SCOUT and CODE as OLE servers in your own applications you had – up to now – no chance to verify a correct start of the software. Starting with object generation 5.28 the start-up routine gives information about the attempt to start the software remotely.

To enable response of the server to a calling OLE client the server has to survive a failing start, at least in such a way that it still can react to client requests. Whereas in the past the software would be closed when no proper license was identified it will now continue to run in a restricted mode (and show up in Task Manager).

We have implemented 4 OLE routines to retrieve status information:

  • license_status: returns an integer number charcterizing the state of the program
  • license_status_string: returns a line of text describing the status of the program
  • license_status_details: returns more detailed information about the program status
  • available_program_instances: returns the number of program instances that can be started in addition to the already running instances (most licenses have a limitation concerning the number of instances that can be operated in parallel).
