Here is my _Service _ UDF

With this UDF, you can compile your autoit script and run it as service.

Any comments are welcome.

Hope you'll like it,

1 - changelog Update V4 : 23/10/2013,27/04/2015 Update : V3 on 29/07/2013 Compile the service example to see how to do then you can use the main function for your proper script Choose an appropriate location and copy the script here. open a command prompt, and execute the compiled script with option –I ( must be admin right since vista ) start / execute "services.msc" . You will see a service called "Autoit_service". you can execute "sc query" in a command prompt too. Launch it : it will run the previous compile script. The main function will be executed after the service_init. stop and relaunch the service as you wish.

Examples / Session Change / uses v1 (lock, logon, etc) By HolmesShelock. Awesome work.
Edit : this example doesn't use v2 or v3 method

Example output to give you an idea Examples demos


And for End Users, I've tried to explain the service control manager and the way it works with programs.

Best Practice, by arcker :

/! please read this if you encounter stability issues

I've had to rework on services.au3 to reflect threadsafe.
Threadsafe means each dll call must be on "dllopened" instead of calling dll directly
for example, if you need a function in kernel32.dll, you have to open it and call it after.
That's contraignant since a lot of integrated functions in autoit are not programmed this way.
If you take my services.au3, at the end, you'll see reworked function to handle this change. I've not tried
services for a while, since i don't need it for now, but i can help you only if your provide whole script, to see how you call every functions.
I can tell that fix stability issues in callback, but i don't think it's need for your script, as far as you don't use callback.

Best Practice, by udgeen :

Good news! Probably i've found the working method of integrating service.au3 with other projects

I realised it after ASock.au3 project by Zatorg (please, sorry if im wrong) - ASock is asynck socket - tcp on event (uses ws2_32.dll).

Asock & sqlite didnt work together. The only reason for that was..._ArrayDisplay() func with gui!!! Ok. I made special sqlite.au3 without dependences. It works, but my udf seemed too be much heavy to use at another project.

Few weeks ago I returned to service.au3 and found TCP UDF, Event driven project based on ASock.au3. It seemed to work as example, but didn't work at all as service.

In my variant of service_example.au3 i posted msdn words about service_main procedure, that it must contain all global vars of project

I'll try to post that project as an another service_example.au3 in some weeks here. If it will works.

Some advice: use SysInternals Process Explorer (free gui based), or kill.exe from support tools to stop suspended service process. U can start-stop service even net start/net stop commands. Use file logging while debuging. No need to install-uninstall service after every recompilation: only stop, recompile, start. See, if it was suspended (while stopping) - kill process. The only reason not to stop service correctly i've found for today is unclean exit: opened sockets, maybe some dlls.
Edit : Arcker note: too bad, that would be too easy. unclean exit is not due to opened dll, but by some more internal exit checks or something.


1 - Hey, I've got error 1063 or error 0, what does that mean ?

It simply means that you intend to run your script in scite or directly by executing it.

Your script has to be installed as service and run from it. Several ways to do it : You have to combine all Globals in one place: for example at the the begining. You have to make it with other udfs too... silly work Then sort Global Const and other Global statements. If u see something like global $x = 1 do that way: global $x leeve at top. $x =1 insert into module's (udf or project) Init func. U have to do it even with standart udf... or use only necessary functions from it in your own include. Or... maybe u have another plan? Try to build your project with modified udfs - does it works now? Hmm... But it have to Maybe later after everything will work fine i'll say "msdn is wrong, microsoft lies"... But maybe i'll say that microsoft - is not so bad, because autoit works in it net start "yourservicename" Services.msc Use API provided _Service_start, Service_stop.  2 - I want to make a GUI !

It's not possible in a service.
Create another process and communicate with your service by using IPC. 3 - I've to let the main function that way ? That's contraignant.

Hey, a script intended to run as service is special no ? Autoit is not C++. The only way to have a "Main" in autoit is to have a function.

If you find another way, please share it ServiceExample_ThreadSafe.au3   Services.au3 ServiceExample_v4.au3 ServicesConstants.au3
