Hi Pat, In order to share an object between processes without using an interprocess variable, you must use the "Storage" container/catalog. In your startup:
Use(Storage) Storage.TriggerState:= New shared object End use Later in your subsequent code, you assign the contents: $MyTrigger:= Storage.TriggerState Use($MyTrigger) $ MyTrigger.processnumber:=$state End use Lahav -----Original Message----- From: 4D_Tech <[email protected]> On Behalf Of Pat Bensky via 4D_Tech Sent: Saturday, October 20, 2018 9:51 AM To: 4D iNug Technical <[email protected]> Cc: Pat Bensky <[email protected]> Subject: Re: Shared Object - NOT! That's how the example in the docs is. I've tried it with a process variable - same problem.
