Windows service questions

Hi, Does a VA Smalltalk application running as a service need to be a headless application? Can a VA Smalltalk application running as a service render graphics? I ask this because a VW headless app cannot draw graphics, so I'm wondering if VA Smalltalk has similar restrictions.

Hi Carl,
you can package a headless application/image including widget classes... I once needed to instantiate a widget in a headless server to access business logic that was included in the controller class of a former fat client implementation(" :-/ "). You simply do not open that widget.... just instantiate it with, I hope I remember right, "createPart". Maybe it is also worth haaving a look at Totally Object's "Notification Area (System Tray)". I had to tweak it a little though it really minimizes properly. But I think running this application as a service didn't work for me, since I needed access to user related data. Could perhaps work for you...

Thanks Sebastian, The application I want to make as a service is a print server. It needs to be able to render report pages with text and graphics and send them to printers. I'll have a look at the Totally Objects stuff. :-) -Carl On Wednesday, September 4, 2013 12:54:30 PM UTC-4, Sebastian Heidbrink wrote: Hi Carl, You received this message because you are subscribed to the Google Groups "VA Smalltalk" group.

Hi Carl,
what do you need the UI for in this case? Sebastian Am 04.09.2013 10:28, schrieb Carl Gundel:

I don't know if I do need a UI, but with VisualWorks if you don't have the UI stuff loaded then you cannot draw graphics. So I wanted to make sure that VA wasn't similarly hampered. I am thinking that an administration UI for this service might make a nice Seaside project. I've done a bit of work with Seaside so that should be pretty easy. -Carl On Wednesday, September 4, 2013 1:37:57 PM UTC-4, Sebastian Heidbrink wrote:

What do you exactly mean with graphics?

Carl,
-- We use the standard printing stuff from VA to send letters to a printer from a headless image running as a service. We also use graphics to print an autograph on the letters. Op woensdag 4 september 2013 19:28:26 UTC+2 schreef Carl Gundel:

I am really conservative about headless system:
-- * all GUI stuff should be removed from such an image * Windows allows pretty much, much more than a standard Linux headless system. * a standard test for Linux headless systems are NOT desktop distributions, but only real server Linux distributions.

GUI stuff should be removed from a headless image, fine. Graphics drawing is not the same thing. Drawing graphics, saving and loading graphics files, etc. are perfectly reasonable (and useful) things for a web application server to be able to do, for example. -Carl On Sunday, September 8, 2013 4:05:18 AM UTC-4, Marten Feldtmann wrote:
