-956 Error

I'm using the Ultralite component on a Palm App. I'm getting a -956 when I
try and synchronise, which suggests a ULInitSynchInfo problem - I don't
understand - can anyone help?

DECLARATIONS
==============

ul_char* mem_pc_OpenParms;
Connection* mem_puc_connection;
DatabaseManager *mem_puc_dbManager;
Table* mem_puc_table;

SOURCE
========

static char szStream_parms[40];

if ( mem_puc_connection)
{
mem_puc_connection->InitSynchInfo( &mem_us_synch_info );
}

ULInitSynchInfo ( &mem_us_synch_info );
GetUserInformation ();

//synch_info.stream = ULSocketStream();
mem_us_synch_info.stream = ULHTTPStream();

Int16 i_len = mem_str_Server.GetLength ();
StrPrintF (szStream_parms, "host=%s;port=2440", mem_str_Server.GetBuffer
(i_len));
mem_us_synch_info.stream_parms = UL_TEXT (szStream_parms);

// for ping requests uncomment the following line!
//synch_info.ping = ul_true;

// set the callback function
mem_us_synch_info.observer = ObserverFunc;

//save state and synchronise
if ( mem_puc_connection )
{
mem_puc_connection->SetSynchInfo ( & mem_us_synch_info );
mem_puc_connection->Synchronize( &mem_us_synch_info );
an_sql_code i_index = Sqlca.GetSQLCode ();

mem_b_previousSynch = true;
}

PrgStopDialog(gSynch
Progress, true);
gSynchProgress = NULL;

Disconnect ();

What version are you using and what build number ?

I do not think the call to ULInitSyncInfo is necessary. That is a function
from the embedded SQL interface. You seem to be using C++ component api
interface. The call to InitSyncInfo already initialized the structure so you
should be okay with just removing the call to ULInitSynchInfo

I'm using ASA 9.0.1 1899.

I've removed the ULInitSynchInfo command.

I still get the -956 Error.

I noticed in the documentation that it refers to a init_verify method - can
you explain this?

Many thanks

You don't seem to be setting the mobilink username anywhere, which would
give this error. This would be the user_name field on the ul_synch_info
structure. You should also probably specify the MobiLink script version.
Also, I would start simple and comment out the observer function until
you get basic connectivity working.

You might also want to post this to the UltraLite newsgroup, which is
where the UltraLite experts hangout.
