POST(Event:CloseWindow) by Timer embed in NT app

[Richard I]

I have the need to close a running NT app by code
This is the code..
If CON:AutoClose =1
If Clock()> Man:Closetime and Con:lastClosedate < today()

Con:lastClosedate = today()
Access:Control Update()
POST(Event:Closewindow)
END
END
I can achieve the close window but the code is not updating from the Webserver's Timer Embed.
Is there an alternative embed that will run the code update and then close the window?
Thanks
