I have a small application (MDI) that is running as a service using the timer event on the only sheet in the application. The timer event is set at 5 sec interval. When the event is triggered, it checks to see if it is currently processing any requests. If it is then it exits the event and waits another 5 seconds. If it is not running then it executes the 'process' function and exits the timer event. The process function sets an instance boolean to true and processes the requests (printing labels). When the process function is done, it sets the boolean to false.
Timer event:
if Ib_processing then
return
else
of_process()
end if
Of_process():
ib_processing = true
// retrieve data from database and process //
Ib_process = false
return
This is very basic stuff. Most of the time there are no requests to process. However, every 5 seconds the application grows 34Kb. Not a lot but over several days it gets very large. I could understand this if it was constantly printing labels as other objects are invovled and there may be an issue with thos objects. I did test this with the queue empty (database table has no rows) and let it run for a couple of hours and it still grows.
I have read some of the other posts about nulling out arrays but this application does not use any. It basically retrieves a list via a datawindow (which is only created once on the open event) and spins through the list. If no rows are retrieved, it will exit the function.
Any Ideas??
