Summary

Check the number of running instances.

Pascal

 public procedure CheckMultipleInstances(MaxInstances: Word; MaxSessionInstances: Word = 0; MaxUserInstances: Word = 0);

Parameters

Parameters	Description
MaxInstances: Word	Maximum count of instances

Description

CheckMultipleInstances determines whether fewer than MaxInstances application instances are running. If this is true, the process is registered as a running instance and a notification is sent to all other running instances, otherwise the method brings the first instance of the application to the foreground and then terminates itself (as such the routine never returns).
