Please contribute it! !!!!Notes: For infoLevel only SC_STATUS_PROCESS_INFO (0x0) is allowed . See [SERVICE_STATUS_PROCESS] definition. See [OpenService] to get the hService. None. !!!!Tips & Tricks: Please add some! !!!!Sample Code: //This code is my first attempt at API calls, it works but has very little error handling so should only be used as a base not as final code. //NB for this code to work you will need to change the [SERVICE_STATUS_PROCESS] class to a struct //NB for this to work you will need to mark the assembly as Unsafe. public static SERVICE_STATUS_PROCESS QueryServiceStatusEx(SafeHandle serviceHandle) { unsafe { IntPtr pData=IntPtr.Zero; try { int iReqSize = 0; pData = Marshal.AllocHGlobal(sizeof(SERVICE_STATUS_PROCESS)); bool bOk = QueryServiceStatusEx(serviceHandle.DangerousGetHandle(), 0, pData, sizeof(SERVICE_STATUS_PROCESS), out iReqSize); if (!bOk) { throw new Win32Exception(); } SERVICE_STATUS_PROCESS pStatus = (SERVICE_STATUS_PROCESS)Marshal.PtrToStructure(pData, typeof(SERVICE_STATUS_PROCESS)); return pStatus; } finally { if (!pData.Equals(IntPtr.Zero)) Marshal.FreeHGlobal(pData); } } Documentation: QueryServiceStatusEx@msdn on MSDN
