Service Login -- API to Change it?

[Camel Software]

I'd like to write a C# program that can change the login for a service
that's already installed. I'm wondering if there is an API to use for that.
I'm familiar with ServiceController, but I don't see a way to use it.

Is it possible?

If so, how should I approach it?

Thanks,
Steve Harclerode

I you talk about Web Service you probably can implement HttpModule with you
login method.

Sorry, I guess I should have said that I'm talking about a Windows Service,
not a web service.

Use the System.Management classes with the WMI Win32_Service class to change
service properties.
Check the Platform SDK -Windows Management Instrumentation for details.

Here's a sample...

public static int ChangeService(string Name, string Password, string
serviceName)
{
ManagementBaseObject inParams = null;
ManagementObject srvc = new ManagementObject("Win32_Service=" + "\"" +
serviceName + "\"");
inParams = srvc.GetMethodParameters("Change");
inParams["StartName"] = Name; //account name .\\localaccount;
domain\\domainaccount (or account@somedomain on XP and up)
inParams["StartPassword"] = Password; // password
ManagementBaseObject outParams = srvc.InvokeMethod("Change", inParams,
null);
return System.Convert.ToInt32(outParams.Properties["ReturnValue"].Value);
}
}

Thank you! Is WMI the recommended method to do this sort of thing now? Rob
mentioned ChangeServiceConfig(), but I'm guessing that someday it will be
considered the "old" way.

Thanks, this is exactly what I was looking for.

WMI is a framework to provide for unified and remote (and neat scriptable)
system administration and management.
There is overhead in using WMI vs. a native Windows export function, but I
don't think either will entirely supplant the other. They both have their
advantages, and I don't see either going away any time soon.
