Extension Manager - problem

HCL Domino Domino Forum

HiI wrote extension manager add-in with c api. I registered EM_NSFNOTEUPDATE event handler. The code of handler is:

STATUS LNPUBLIC handler(EMRECORD far *data) {

    VARARG_PTR ap;

    NOTEHANDLE hNote;

	        

    if (EM_NSFNOTEUPDATE != data->EId)

            return (ERR_EM_CONTINUE);



ap = data->Ap;

hNote = VARARG_GET (ap, NOTEHANDLE);

[...]

hNote is NULLHANDLE after this. Why? This is running on linux 2.4 (slackware). I tried:

VARARG_COPY(ap, data->Ap);

before WARARG_GET but with the same result.

You need to check for EM_BEFORE or EM_AFTER. In this case, you should have

    if (EM_NSFNOTEUPDATE != data->EId)

            return (ERR_EM_CONTINUE);



   if (data->NotificationType == EM_BEFORE)

            return (ERR_EM_CONTINUE);



ap = data->Ap;

hNote = VARARG_GET (ap, NOTEHANDLE);

I registered EM_BEFORE because I need a valid note handle. I’m checking data->NotificationType and it’s always EM_BEFORE. When I register handler as EM_AFTER, hNote is NULLHANDLE too.

I’m sorry, I wrote it wrong anyway. You want the EM_BEFORE, but not the EM_AFTER. In any case, if you are getting an invalid handle, it must be a different issue.

The following is code I use that works:

case EM_NSFNOTEUPDATE:

case EM_NSFNOTEUPDATEXTENDED:

  if (pExRecord->Status != NOERROR)

    break;



  if (pExRecord->NotificationType == EM_AFTER)

    break;



  pArgs = pExRecord->Ap;

  hNote = VARARG_GET (pArgs, NOTEHANDLE);

  if (hNote == NULLHANDLE)

    return( ERR_EM_CONTINUE );



  /* Filtering for database, if there are any filters */

  NSFNoteGetInfo(hNote, _NOTE_DB, &hDB);



  sError = ProcessUpdateEvent(hDB, hNote, clientstr, web_server);

  if (sError == NOERROR)

    return (ERR_EM_CONTINUE);



  break;

but I have not actually used it in slackware Linux. The check for hnote == NULLHANDLE has always been in there because there are some spurious updates which you don’t want to trap. Are you sure that is not what you are seeing?

Extension Manager calls handler corectly on each dokument update. All events are the same: STATUS == NOERROR and hNote == NULLHANDLE.

What is your operating system?
