Squeak as an NT service

Hi Andreas,
I once wrote an NT Service sample which allows you to easily create a
windows service
in Smalltalk. It is included in the Smalltalk MT distribution. You can check
out their
test version (www.objectconnect.com or www.genify.com) to see how it's done
or try the
following:
Anything you have to do is to set the appropriate startup (dwStartupType)
type when
you call the CreateService()-API. SERVICE_AUTO_START will specify a service
who will
be started automatically by the service control manager during system
startup.
My SmalltalkMT Service also initializes the service state like the
following:
WinNTService>>initialize
...
status := SERVICE_STATUS new. "service state structure"
status dwServiceType: SERVICE_WIN32_OWN_PROCESS; "this
service only contains the code for one service"
dwCurrentState: SERVICE_STOPPED;
dwControlsAccepted:
SERVICE_ACCEPT_STOP|SERVICE_ACCEPT_SHUTDOWN; "the service accepts
start/stop"
dwWin32ExitCode: 0;
dwServiceSpecificExitCode: 0;
dwCheckPoint: 0;
dwWaitHint: 0.
self status: status; "set state and update using
SetServiceStatus()-API"
isRunning: false.
SERVICE_ACCEPT_SHUTDOWN means: The service is notified when system shutdown
occurs. This flag allows the service
to receive the SERVICE_CONTROL_SHUTDOWN value. Note that ControlService
cannot send this control code; only the
system can send SERVICE_CONTROL_SHUTDOWN.
Check out the following pages in the MSDN or search for one of the flags/api
functions in the library:

Hope this helps

Peter,
It may certainly be useful, but the fact of the matter is that I have no
idea of how to make it happen :-( Any Windows hackers out there who can
help?!
