#7051 — Multiple windows services on the same machine

Hi everyone, I'm writing a script which implement a windows service
with the win32serviceutil module. The service works perfectly, but now
I would need to install several instances of the same service on my
machine for testing purpose.
This is hard since the service name is hard-coded in the service class
definition:

class MyService(win32serviceutil.ServiceFramework) :
    _svc_name_ = 'MyService'
    _svc_display_name_ = 'Instance ofMyService'

    def __init__(self, args) :
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)

    def SvcStop(self) :
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        sys.stopservice = "true"
        win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self) :
        #Do something...

So can anyone point me out which is the best way to "parametrize" the
service name? Thanks in advance for your help!

Could you not make the ‘_svc_display_name’ an instance attribute instead
of class attribute?

That is, don't set it as an attribute on the class; instead, set it as
an attribute on the instance during initialisation (the ‘__init__’
method).

It is only hard-coded in the HandleCommandLine function - you probably 
just want your own argv parsing and call InstallService directly.

HTH,

Mark
