Hello everybody…

i have written this simple code

switch (pExRecord->EId)

{

/* Extension Manager hook EM_MAILSENDNOTE */

case EM_NSFNOTEUPDATEMAILBOX:

{

    /* check error code */

    if (pExRecord->Status != NOERROR)

	  break;



    LogLine("-------------------------------------------------\n");

    sprintf(gTextBuffer, "Calling EM_NSFNOTEUPDATEMAILBOX\n");

    LogLine( gTextBuffer );



    if (pExRecord->NotificationType == EM_BEFORE)

      sprintf(gTextBuffer, "EM_BEFORE...\n");

    else if (pExRecord->NotificationType == EM_AFTER)

      sprintf(gTextBuffer, "EM_AFTER...\n");

	LogLine(gTextBuffer);

    break;

} /* end of case */

} /* end of switch */

…but i have a problem…

in my log file i have four lines- 2 for EM_BEFORE and 2 for EM_AFTER…

can anyone tell my why?

thank you in advance

i’m new in extension managers…so would you be so kind to tell me what do you mean by “checking recursion ID”?

thank you

Subject: RE: *Do you check the recursion id?

The prototype for this function is:

STATUS LNPUBLIC EMCreateRecursionID(

WORD far *retRecursionID);

Follow the EM samples provided in the C API toolkit to implement you EM program.

Subject: RE: *Do you check the recursion id?

i followed your instructions regardinf the hnote…

and i noticed thet for one pair EM_BEFORE-EM_AFTER i have the same hnote, for the other pair EM_BEFORE-EM_AFTER i have another hnote

is it possible that this EM is triggered when the note is created in mail.box and then deleted?

Subject: *Yes, it is quite possible.

Subject: RE: *Do you check the recursion id?

Possible…

In the EM_AFTER, try the following…

if (nid & RRV_DELETED)

deleted

else

not deleted

Subject: RE: *Do you check the recursion id?

here is the code…

iif(nid & RRV_DELETED)

		sprintf(gTextBuffer, "deleted\n");

	else

		sprintf(gTextBuffer, "not deleted\n");

	LogLine(gTextBuffer);

…and the log result…

and what is the meaning of 0 Flags?

first em is the message going into mail.box, second em is the message going out (ie actually sent/deleted).

use something like this (it’s from a sub so you probably don’t need the first two lines - i like to double check)

// check em details

if( pExRecord->EId != EM_NSFNOTEUPDATEMAILBOX ) goto Exit;

if( pExRecord->NotificationType != EM_BEFORE ) goto Exit;

if( pExRecord->Status != NOERROR ) goto Exit;



// get em parameters

ap = pExRecord->Ap;

EM_SourceNote = VARARG_GET( ap, HANDLE );

EM_UpdateFlags = VARARG_GET( ap, WORD );



// abort if update_deleted

if( UPDATE_DELETED == ( UPDATE_DELETED & EM_UpdateFlags ) ) goto Exit;

yes, this works just fine

thank you very much

Hi Alexandru,

I think one set of before and after messages is for the mail.box and the other set is for the mail database being updated.

You can can the database handle and filename from the nHandle to verify the databases associated with the EM_NSFNOTEUPDATEMAILBOX message.

NSFNoteGetInfo(nHandle, _NOTE_DB, &dbHandle);

sStauts = NSFDbReopen(dbHandle, &dbHandlex);

sStatus = NSFDbPathGet(dbHandlex, szCanonical, szExpanded);

NSFDbClose(dbHandlex);

Let me know your results.

Regards,

here is the new result…

Calling EM_NSFNOTEUPDATEMAILBOX

Expanded path: C:\Lotus\Domino\Data\mail.box

the second EM_BEFORE is identical…

any ideeas?

Subject: RE: EM_NSFNOTEUPDATEMAILBOX

Hmmm…

Try aquiring the NOTE ID in the EM_AFTER to see what value is returned.

NSFNoteGetInfo(nHandle, _NOTE_ID, &nid);
