    Stopping a service

    I'm trying to stop a sertvice, but the OpenService function fails, saying that the service doesn't exist...

    The GetErr function is just a function which returns system error info as text.

    Code:
    int stopSvc(LPTSTR achSvc){
      SERVICE_STATUS_PROCESS sp;
      SERVICE_STATUS ss;
      SC_HANDLE hScM, hSvc;
      DWORD dwBytesNeeded;
    
      if((hScM=OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS))){
        if((hSvc=OpenService(hScM, achSvc, SERVICE_ALL_ACCESS))){
          if(!QueryServiceStatusEx(hSvc, SC_STATUS_PROCESS_INFO, (LPBYTE)&sp, sizeof(SERVICE_STATUS_PROCESS), &dwBytesNeeded)){
            GetErr("QueryServiceStatusEx");
            return(0);
          }else if(sp.dwCurrentState == SERVICE_STOPPED) 
            return(1);
          if(ControlService(hSvc, SERVICE_CONTROL_STOP, &ss)>0){
            CloseServiceHandle(hSvc);
            CloseServiceHandle(hScM);
            return(1);
          }else
            GetErr("ControlService");
        }else
          GetErr("OpenService");
        CloseServiceHandle(hSvc);
      }else
        GetErr("OpenSCManager");
      CloseServiceHandle(hScM);
      return(0);
    }
    The service is running on the local machine, and I'm logged on as admin. Running XP SP2/VC.Net.
    Any clues?

    Found the error. I'm trying to stop the service by it's display name.. I'll have to find the actual name of the service instead..
