The code below ( I don't know who wrote it, I tried to search the forums)
I'm compiling the code to x86, but need it to run on both x86 and x64.

The code works fine on x86, but on x64 it does not. (always telling me that a system shutdown is in progress)

Is this going to be doable? If so, any tips on how to get it going on x64 (while still compiling to 32bits)

thanks!

It works as it is here, compiled to 32 bit and running under x64 (win7)

BTW: You don't need to define the structure, it's already defined in PB as SERVICE_STATUS.

Code: Select all

Procedure.i QuerySvc(svcName.s)
   Protected nStatus
   Protected service.SERVICE_STATUS

   Protected LastError = 0
   Protected lpMachineName = #Null, lpDatabaseName = #Null,scmDesiredAccess = #SC_MANAGER_ALL_ACCESS,svcDesiredAccess = #SERVICE_ALL_ACCESS
   Protected scmHandler = OpenSCManager_(lpMachineName, lpDatabaseName, scmDesiredAccess)
   
   If scmHandler = #Null
     LastError = GetLastError_()
     Debug("Open SCM failed with error " + Str(LastError))
   Else
    Protected svcHandler = OpenService_(scmHandler, svcName, svcDesiredAccess)
    If svcHandler = #Null
      LastError = GetLastError_()
      Debug("Open Service failed with error " + Str(LastError))
    Else
      Protected Result = QueryServiceStatus_(svcHandler, service)
      If Result = 0
        LastError = GetLastError_()
        Debug("Query failed with error " + Str(LastError))
      Else
         nStatus = service\dwCurrentState
         Debug("Service state: "+Str(nStatus))
      EndIf
      Result = CloseServiceHandle_(svcHandler) 
    EndIf
     Result = CloseServiceHandle_(scmHandler)
  EndIf

  If LastError
     nStatus = -1 * LastError
  EndIf
 
  ProcedureReturn nStatus
EndProcedure

Debug("Query: "+Str(QuerySvc("LanmanWorkstation")))

Returns 4 (service is running)

Thanks luis.
What I discovered is that on some os's when windows updates are installed and need a reboot (iow: the nag screen to reboot after updates) the service query fails with "the system is shutting down" even tho it's not.
