If Foresight Analytics Platform is started with the singleinstance key for activation of the application started earlier, the BeforeInstanceActivate message will be sent to all started forms. The first form that processes this message and returns the value not equal to 0, will be activated. The form that processed the BeforeInstanceActivate message will also get the AfterInstanceActivate message. Messages should be processed in the OnCommand event.
