C API - How do I delete attachments properly with NSFNoteDetachFile()

HCL Domino Domino Forum

If I send a message with an attachment from one notes user to another and then use my program to remove the attachment which uses NSFNoteDetachFile() function everything works fine.

But if I send an email from Outlook Express to a notes user and then use my program to remove the attachment something strange happens. I go into the mail box and try to forward the message and I get this error" Unable to copy file attachment: Server error: This database cannot be read due to an invalid on disk structure"

Can anyone help shed some light on this?

Thank you.

I’ve done this many times and never had a problem. I’ve never tried the exact scenario that you’ve described, but I could try to duplicate the test scenario and let you know. Are you using MailGetMessageAttachmentInfo to return the BLOCKID?

(pulled out of context but you get the idea)

MailGetMessageAttachmentInfo(hNote,0,&bidAttachment,szFilename,NULL,NULL,NULL,NULL,NULL);

NSFNoteDetachFile(hNote,bidAttachment);

NSFNoteUpdate(hNote,0);

NSFNoteClose(hNote);

Actually, the customer solution that this code was for left the attachment rendering in the body so the user knew there had been an attachment that was deleted.

I think you’d have to go into the body and edit the rich text to remove the icon rendering, i.e. the data between the CDHOTSPOTBEGIN and CDHOTSPOTEND tags.

Is the file attachment in a rich text field? If so, and if you just remove the attachment but don’t remove the file hotspot, the conversion to SMTP to go to Outlook will likely fail.

Sorry for the delay and thank you to those who have written. This sounds like my problem. I thought I just needed to detach the attachment. How do I remove the hotspot? Because of this problem, should I test for the hotspot each time or will I be required to remove it everytime? Do you have a small example of how to properly remove an attachment that does not have this problem?

Thanks
