REVENGINE (Openinsight.exe) (OpenInsight 64-bit)

I have an application that starts as a mdi form, but is not visible as it firsts displays a dialogbox for user login.

When the the cancel button is pressed and returns from the dialog with no values, it then closes the mdi and does: 


Void = send_Event(MDI_Frame@, "CLOSE" )

call set_property_only("SYSTEM","SHUTDOWN",1)

// Close the application

Call Exec_Method( "SYSTEM", "DESTROY", "SYSTEM" )

the application closes, but the revengine is still open.

How can I CLOSE the revengine programmatically so that it no longer running (openinsight.exe in the task manager)

Hi Barry,

The PS will shut the system down when it detects that there are no more running OI forms - RevEngine isn't an OI form so this doesn't enter into that calculation, so there's something else in play.

If your MDI Form is indeed closed then you shouldn't need any more calls to shut down the system - it should already in process, so the first thing to check is if there are any more hidden forms running? The only thing that will stop the auto-destroy is the SUPPRESSAUTODESTROY property - are you setting that anywhere in your app?

Next point - setting the SHUTDOWN property and calling the DESTROY method are doing the same thing - you don't need both - perhaps that might cause a conflict, though I couldn't think why off the top of my head.

SUPPRESSAUTODESTROY - is being set, that was going to be my next observation alert for you.

Also, where can I see what what forms are running. Debug show VSPRINTER2 as the only 'FORM' properties, started to help with report init speed.

Added a set_printer("TERM") but still shows in debug (I am probably down the wrong rabbit hole here).

My suspicion has always been the SUPPRESSAUTODESTROY (Just though now I could try setting to 0)

YEP!!

Call Set_Property_only( "SYSTEM", "SUPPRESSAUTODESTROY", false$ )

fixed the issue

Use SUPPRESSAUTODESTROY with care - it's only meant to be used in very limited and specific circumstances

You can get a list of running forms easily via the system monitor using the "LO" (List Objects) command: 

lo "" window

Will do it.

These commands are documented in the "Introduction" doc on the RevDevX blog.

fixed the issue

Whoops, spoke too soon.

This works if I run oi with dv=1 and the tools→launch application.

But id run with dv=0 (run application) it comes up with error msg:

<appname> initialisation

PSSI.01: No visible entry window started for the <appname> application. Process aborted

*

then application close but revengine still running.

Trimmed down to this: 

                     Call Set_Property_only( "SYSTEM", "SUPPRESSAUTODESTROY", false$ )

* Void = send_Event(MDI_Frame@, "CLOSE")

* Call Exec_Method( "SYSTEM", "DESTROY", "SYSTEM" )

This is the sledgehammer commands I also tried: 

                    Call Set_Property_only( "SYSTEM", "SUPPRESSAUTODESTROY", false$ )
		foo  = set_printer("TERM",2)
		call set_property_only(MDI_Frame@, "VISIBLE",1)
		Void = send_Event(MDI_Frame@, "CLOSE")
		Void = Send_Event(@Window, "CLOSE")
		// Close the application
	       Call Exec_Method( "SYSTEM", "DESTROY", "SYSTEM" )

Obviously there is something else at play here.

Ok, now works, what you said earlier was correct about clash.

For the avoidance of doubt - here's the pseudo-code for starting an application in the PS:

   end else

      ERROR: PSSI.00: No entry window defined for the %1% application.

   end

   

   if ERROR then

      if SysMonIsVisible then

         OutputErrorToSysMon
