TStringList *ListServices(int ServiceType)

   TStringList *list = new TStringList();
   SC_HANDLE schSCManager   = OpenSCManager(NULL,NULL, SC_MANAGER_ALL_ACCESS);
   LPBYTE    lpServices;
   DWORD    n,nSize,npSize,nServicesReturned,nResumeHandle,dwServiceType;

    {
        nResumeHandle  =0;
        npSize   =   sizeof(ENUM_SERVICE_STATUS_PROCESS);

        dwServiceType   = SERVICE_WIN32   |   SERVICE_DRIVER  |
                        SERVICE_KERNEL_DRIVER   |  SERVICE_FILE_SYSTEM_DRIVER   |
                        SERVICE_WIN32_OWN_PROCESS   |  SERVICE_WIN32_SHARE_PROCESS;

        lpServices   =   LPBYTE(LocalAlloc(LPTR,   30720));
        try
        {
            if  (!EnumServicesStatusEx(schSCManager, SC_ENUM_PROCESS_INFO,
                dwServiceType,   SERVICE_STATE_ALL,   lpServices,   30720,
                &nSize,   &nServicesReturned,&nResumeHandle, NULL))

                return list;
           }

        for( n = 0;n< nServicesReturned-1;n++)
        {
                //Show   the   name   of   service
               //    ListItem   :=   SvcListView.Items.Add;

               //    ListItem.SubItems.Add((LPENUM_SERVICE_STATUS_PROCESS(lpServices))^.lpDisplayName);
               // ListItem.SubItems.Add(IntToStr((LPENUM_SERVICE_STATUS_PROCESS(lpServices))^.ServiceStatusProcess.dwProcessId));
               // ListItem.SubItems.Add(SrvStatus((LPENUM_SERVICE_STATUS_PROCESS(lpServices))^.ServiceStatusProcess.dwCurrentState));
               String ss = (LPENUM_SERVICE_STATUS_PROCESS(lpServices))->lpServiceName  ;
                String ss2 = (LPENUM_SERVICE_STATUS_PROCESS(lpServices))->lpDisplayName  ;
               list->Add(ss2);
               if (ss2 == "wwServices") {
                    ShowMessage(ss2);
               }
                lpServices +=   npSize;
            }
            return list;
           }
        __finally

           {
           //    if  ( lpServices   != NULL)
           //        LocalFree(int(lpServices));
       }
    }
}

以上代码需引用winsvc.h文件，为C++Builder2010编写，基本就是两个api，但不知为何所有的服务都列出来的，单单就是我用C++Builder2010写的一个服务程序无法找到？？
