Summary

The WM_SPOOLERSTATUS message is not supported after Windows XP. Occurs whenever a job is added to or removed from the Print Manager queue.

Pascal

 TJvSpoolerChangeEvent = procedure (Sender: TObject; JobStatus, JobsLeft: Integer) ofobject;
propertyOnSpoolerStatusChange: TJvSpoolerChangeEvent;

Parameters

Parameters	Description
JobsLeft	Number of jobs remaining.
JobStatus	Specifies the PR_JOBSTATUS flag.
Sender	The object that triggered the event.

Description

Write a handler for this event to take specific actions when print jobs are added or removed from the print queue. This event is triggered in response to a WM_SPOOLERSTATUS message. This event is advisory and does not have guaranteed delivery semantics. Applications should not assume that they will receive this event for every change in spooler status.
