start service before lock on

Hi,

How can I get it, that a service starts before the log on?

Thank you for your help!

What "lock on"?

Sorry, I mine log on.

When you create your service using the CreateService function you specify the type of service as SERVICE_AUTO_START. See the doco on CreateService for more details and other options.

I have done that, but the service starts after the log on and not before.
Or is only the program I started with the service not visible?

What does your service do? Can you explain what you mean by visible?

My service starts an OnScreenKeyboard, which I need for the log on.

what have you specified for the lpServiceStartName? Better yet, please code you are using to install the service and any service configuration

1) "lock on"? - Phasers or PHoton Torpedeos...
2) "Sorry, I mine log on."....You want to lock weapons on a space mine???

(just could not resist...)

A couple of points....

1) Automatic Services start Automatically when they are needed. You can configure for an actual start (once you post your code so we can show a relatively compataible way...).

HEre is where you are going to run into trouble. The exact nature will depend on your OS and even SP.

Login is done by a special "highly secure" program known as a "GINA". It is specifically designed to minimize tampering for fairly objious reasons.

Even if you get your "On-Screen Keyboard" to START, it is VERY unlikely that you will get it to properly interact with the default GINA.

You will be much better off simply writing a custom GINA that utilizes the functionallity of your application directly.

my code:

Code:

---

inline BOOL CServiceModule::Install()
{
    if (IsInstalled())
        return TRUE;

    SC_HANDLE hSCM = ::OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
    if (hSCM == NULL)
    {
        MessageBox(NULL, _T("Couldn't open service manager"), m_szServiceName, MB_OK);
        return FALSE;
    }

      TCHAR szFilePath[150];
    ::GetModuleFileName(NULL, szFilePath, _MAX_PATH);

    SC_HANDLE hService = ::CreateService(hSCM, m_szServiceName, m_szServiceName, SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS | SERVICE_INTERACTIVE_PROCESS, SERVICE_AUTO_START,  SERVICE_ERROR_NORMAL, szFilePath,  NULL, NULL,  NULL,  NULL,  NULL);

    if (hService == NULL)
    {
        ::CloseServiceHandle(hSCM);
        MessageBox(NULL, _T("Couldn't create service"), m_szServiceName, MB_OK);
        return FALSE;
    }

    ::CloseServiceHandle(hService);
    ::CloseServiceHandle(hSCM);
    return TRUE;
}

GINA DLLs are ignored in Windows Vista.

I need something that works on vista and xp.

Can nobody help me??

I have an another OSK seen that before the LogOn starts, but apparently does not have its own GINA. On the computer I could not found any unknown GINA. I know only that there is a service. Has anyone of you an idea??

Okay-okay, I can't stand your suffering. :)

lpLoadOrderGroup [in, optional]

The names of the load ordering group of which this service is a member. Specify NULL or an empty string if the service does not belong to a group.

The startup program uses load ordering groups to load groups of services in a specified order with respect to the other groups. The list of load ordering groups is contained in the following registry value:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ServiceGroupOrder

---

A service start order is defined by the group service belongs to. Just create your service with group specification. Base worked fine in my experiments - my service had been started even before main GINA interface had shown login dialog, even in XP which is well known slow goer in aspect of initializing services.

Hi Igor Vartanov,

thank you for your post.
I have done what you have wrote, but it doesn't work.

Code:

---

SC_HANDLE hService = ::CreateService(hSCM, m_szServiceName, m_szServiceName, SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS | SERVICE_INTERACTIVE_PROCESS, SERVICE_AUTO_START, SERVICE_ERROR_NORMAL, szFilePath, "Base", NULL, NULL,  NULL,  NULL );

---

With this change it takes a littel bit longer before the main GINA interface hade shown the login dialog, but not more.
Can you give me your sample code?
