ServiceController & TServiceState

When TServiceController.CreateOpenService succeeds at opening the SC Manager, but fails at OpenService, it ends up in a state with FSCHandle <> 0 and FHandle = 0

However TServiceController.GetState then proceeds to report that as ssNotInstalled, when it should be ssErrorRetrievingState, or some more detailed information should be preserved.

Lists the cases when OpenService can return a null handle, among which ERROR_ACCESS_DENIED and ERROR_INVALID_NAME do not correspond to a service not installed.

Re: ServiceController & TServiceState

This improves things for insufficient rights, but seemed to fail reporting when the service really was not installed.

I have gone the extra mile here by introducing a TServiceStateEx with an ssAccessDenied element, and checking the GetLastError after calling CreateOpenService.
