Hi,
I want my code to automatically start a service if it's not already running when my program starts, then stop upon exit. I found the code to do this, but my program just gives me access denid errors when started. I believe I have to do some hockery pockery with tokens? although I cant find the code anywhere to do this, just wondering if anyone could help me out
thanks
Could you give some more information. Where do you want to start the service, local or on a network device?
Give some more details about the exception, (kind of exception, innerexception)
Hi, the service is a local service and the exception it throws is :
System.InvalidOperationException was unhandled
Message="Cannot open screen-scraper server service on computer '.'."
Source="System.ServiceProcess"
StackTrace:

NativeErrorCode=5
InnerException:
as you can see it says InnerException: System.ComponentModel.Win32Exception
Message="Access is denied", so I presumed that has something to do with windows permissions?
Please post the code you use to start the service (and use [code ] [/ code] tags).
Check this thread for a discussion of some of the permission type issues you will run into...
ServiceController sc = new ServiceController("screen scraper server");
if(sc.Status.Equals(ServiceControllerStatus.Stopped)){
sc.Start();
}
is the basic code I'm using to check if the service is running already, and if not then to start it. I know it's recognising the service etc, no problem getting status and things like that, just don't have the permissions to start/stop the service. Still can't find a way to do this..
Did you follow the links in the next to last two replies in the thread I provided???Quote:
