create service on windows

问题

I am having trouble starting my service on my pc. My code is based on this article http://www.gamedev.net/reference/articles/article1899.asp

When i call installService from my int main(int argc, char *argv[]), it is registered successfully (i can see it in msconfig and services.msc). However it has not started. I manually start the service via services.msv and i get the error "Error 2: system cannot find the file specified". Why is this? i registered the services no more then a min ago, my external HD is still on (where this is currently stored. i'll move a nondev version to c:/ when its ready) What am i doing wrong and is there another tutorial i can look at (i only found the one linked via google)

#define srvName "MyTestService_01312009"

void installService(char*path)
{
    SC_HANDLE handle = ::OpenSCManager( NULL, NULL, SC_MANAGER_ALL_ACCESS );
    SC_HANDLE service = ::CreateService(
        handle,
        srvName,
        "MyTestService_01312009b",
        GENERIC_READ | GENERIC_EXECUTE,
        SERVICE_WIN32_OWN_PROCESS,
        SERVICE_AUTO_START,
        SERVICE_ERROR_IGNORE,
        path,
        NULL,
        NULL,
        NULL,
        NULL,
        NULL
    );
}
void uninstallService()
{
    SC_HANDLE handle = ::OpenSCManager( NULL, NULL, SC_MANAGER_ALL_ACCESS );//?
    SC_HANDLE service = ::OpenService( handle, srvName, DELETE );
    if( service != NULL )
    {
        // remove the service!
        ::DeleteService( service );
    }
}

SERVICE_STATUS_HANDLE hStatus;
SERVICE_STATUS status;

/*
if( ::StartServiceCtrlDispatcher( dispatchTable ) == 0 )
{
    // if this fails, it's probably because someone started us from
    // the command line.  Print a message telling them the "usage"
}
*/
void WINAPI ServiceCtrlHandler( DWORD control )
{
    switch( control )
    {
    case SERVICE_CONTROL_SHUTDOWN:
    case SERVICE_CONTROL_STOP:
        // do shutdown stuff here

        status.dwCurrentState = SERVICE_STOPPED;
        status.dwWin32ExitCode = 0;
        status.dwCheckPoint = 0;
        status.dwWaitHint = 0;
        break;
    case SERVICE_CONTROL_INTERROGATE:
        // just set the current state to whatever it is...
        break;
    }

    ::SetServiceStatus( hStatus, &status );
}
void WINAPI ServiceDispatch( DWORD numArgs, char **args )
{
    // we have to initialize the service-specific stuff
    memset( &status, 0, sizeof(SERVICE_STATUS) );
    status.dwServiceType = SERVICE_WIN32;
    status.dwCurrentState = SERVICE_START_PENDING;
    status.dwControlsAccepted = SERVICE_ACCEPT_STOP;

    hStatus = ::RegisterServiceCtrlHandler( srvName, &ServiceCtrlHandler );

    // more initialization stuff here
    FILE *f = fopen("c:/testSrv.bin", "wb");
    ::SetServiceStatus( hStatus, &status );
}
SERVICE_TABLE_ENTRY dispatchTable[] =
{
    { srvName, &ServiceDispatch },
    { NULL, NULL }
};

Maybe you can use Process Monitor to find out what's wrong.

Start it, and look for NAME NOT FOUND results that occur in connection with the service start.
