Detection of service
TofK
I have some services to stop at the beginning of the installation and
to restart after...
There is no problem at the begining because if Service doesn't exist,
WI will pass without error.
But when he wan't to start a service which is not installed, a dialog
box appear...
Is there a way to detect if service is install on computer and, if
not, to not try to start the service ?
Thanks for your help (and example ;) ),

function OpenSCManager() to get access to the service control manager and then
EnumServiceStatus() to gather information about all of the services. From there
you should be able to OpenService() to get its handle and then ControlService()
to stop it. To start the service again, you would call StartService().

What services? Are they services that you install?

Well... the obvious question is... why are you attempting to start a
service that is not installed?

I would use AppSearch or a custom action to identify the presence of a
service and use that to set a property that conditionalizes the
StartServices action. If there are times when you need to change the
set of services that you start/stop and you can't disable the whole
StartServices action, then I would make a custom action that makes a
temporary modification to the database so that the StartServices
action starts only the necessary services.

I don't know ! In reality, I make a exe which read in configuration
file in order to populate a MSI database. So I don't know what service
will be in this configuration file.

First answer : I don't know the service so I have to test this
possibity.

Umm... you really need to identify the services that you are
attempting to control before you start mucking around with them. I
don't understand how you can know which services to start/stop when
the install is run, but you don't know what they are? If you don't
know what the services are or why you are stopping/starting them, you
need to take a step back and figure out just exactly -why- you are
even attempting to manipulate them in the first place. Either you are
confused about what you are attempting to do, or you haven't really
explained it in your posts.
