Title: Implementing SelfService
Post by: rupertvz on March 25, 2015, 01:14:46 PM

Hi Guys,

I added the SelfService template to one of my apps.
This application used to run with the "NT-service" template.  It is a very small app, I am hiding the application window and it already has a text-file log feature built into it.

Launching MyService /iss
The service installs, but immediately gives a message that the services is not running;
The log file however shows the entries, and the application did what it was supposed to do.

Should it loop automatically?  Or should I built in a loop?
(I had previously used NT-service which included a loop option)

* It seems to start, run the application, then ends .. hence the reason it says "service did not start"?

Hi Rupert,

If you run the program as an exe does it just run once and end? If so that's what it'll do when it runs as a service.
If you want it to stay alive and do something over and over then you need to code it to do that - presumably using a timer event on the window.

no

>> Or should I built in a loop?

if you want it to stay alive and perform some task, then yes, you program it to do that.

>> (I had previously used NT-service which included a loop option)

Sounds like NT-Service is a "wrapper" of sorts that altered the program behavior. SelfService doesn't do that - SS turns your program into a service, after that it does whatever it is you programmed the program to do.

Thanks Bruce,

I am using a source procedure as a "main" procedure, thus no window structure, or procedural timer.

I have in the meantime used a loop procedure with the "sleep" function ... not sure if this is good practice? Sustainable?

Hiding or having no procedure windows worked better for me using NT-Service.

Does it make a difference in Self-Service whether I use / hide procedure-windows from display?

Hi Rupert,

I've not used sleep myself, but I suppose it's ok.
Personally I'd just make a window, put a timer on it, and then put my code in the timer.
It doesn't matter if you hide the window or not - either way the user is not going to see it.
I leave mine "not hidden" so when the program runs as an exe then you can see it.

cheers
