How can I start/stop a driver programmatically (from a user mode app),
instead of ‘net start ’.

Thanks,
Aaron

Hi Arron,

One thing you could do is yes the c programming function system to send a
net start command

If you are using NT 4.0 you can use the ServiceControlManager. Open it by calling openscmanager(), then open a reference to your service with a call to OpenService(),then start your service with StartService() call.
All are documented in MSDN SDK docs.

If you are using Win2k, then it depends. Send more info.

Aaron,

Use the Win32 services API (OpenSCManager, OpenService, StartService,
ControlService, CloseServiceHandle, etc…).

As others have said, use the various service control manager
functions.

However, you may need to watch out for security here. Many of the
drivers are started by the local system so an ordinary user will
not be able to start/stop them (at least this has been by experience,
although it may have been the unique security constraints of the
systems I was working on). I was force to write a service that was
started at boot, and when my user mode application wanted to modify
a driver (start/stop) it would send a message to the service that
would then do the actual work.

Yes, Security could be an issue. I encountered this when I wrote a service
to send mail using the SMTP protocol. The socket could not connect. So I had
to change the “start service as” from local system account to administrator
account. Then it worked fine.
