Posted by andatino loo on 4.Oct.07 at 07:29 AM using a Web browserCategory: Notes ClientRelease: 6.5Platform: Windows 2000 Hi All, A user having a problem to send any attachment file (*.doc,*.xls,*pdf ) to the recipient. The recipient is unable to open,view and save the attachment. The notes client will prompt the recipient an error message as "Encoded data checksum mismatch - attachment may be corrupted". I found that below notes tech site had mention about this is caused by MTU setting. http://www-1.ibm.com/support/docview.wss?uid=swg21204788 Therefore,i had ping the MTU on user 's pc and found that the size of the MTU is same as my pc. Besides that, the user had using other pc to send an email with attachment to the recipient. The recipient could open the attachment without any error. Which means that only that particular PC having some problem. Do you have any idea? Thanks in advance. Return to top Encoded data checksum mismatch - at... (andatino loo 4.Oct.07) . .

Sent from a Certain User Technote (FAQ) Question When users attempt to open attachments contained in messages sent by http://www-10.lotus.com/ldd/nd6forum.nsf/e5f5333619f2996885256a220009508f/3fa5926e6061f0b18525736a003f21d8?OpenDocument a certain user, the following error displays: "Encoded Data Checksum Mismatch - Attachment may be corrupted..." Answer In this case, it appears that the sender's broadband connection from home http://www.ibm.com/support/docview.wss?uid=swg21199057 was corrupting the files. If that user sent messages while dialed into the server via a modem, instead of a broadband connection, the recipients were able to open the attachments without error.

One of the attachments is corrupt, and if I attempt to save it, Notes displays this message The attachment may be corrupted. Would you like to continue with the available data? If I click Yes, Notes saves the corrupt attachment to the directory I specify. This is good. I would like to do the same thing using the object model in C#. If I run NotesEmbeddedObject.ExtractFile(), I receive this exception message: Notes error: notes error encoded Encoded Data Checksum Mismatch - Attachment may be corrupted. No version of the file is written to the directory I specify. I would like for the code to write the corrupted version to a directory. How can I do this? Existing Code: //BEGIN Extract Attachment //nItem is a NotesItem if (nItem.type == IT_TYPE.ATTACHMENT) { try { string pAttachment = ((object[])nItem.Values)[0].ToString(); NotesDocument NDoc = NotesConnectionDatabase.AllDocuments.GetNthDocument(i); NotesEmbeddedObject Neo = NDoc.GetAttachment(pAttachment); NDoc.GetAttachment(pAttachment).ExtractFile(@"D:\projects\xxx\Attach\" + pAttachment); } catch (Exception e) { string eMessage = e.Message; Console.WriteLine(eMessage); } } //END Extract Attachment c# .net lotus-notes lotus lotus-domino share|improve this question edited Jun 1 '12 at 13:28 palacsint 16.3k55080 asked Jun 24 '11 at 17:02 Jacob Quisenberry 416621 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted I'm afraid not. The NotesEmbeddedObject.ExtractFile method attempts to extract the attachment, but there's a checksum mismatch, and as soon as it gets that error, it throws an exception. I don't know of any other Notes back-end classes that deal with attachments (maybe someone else does...) share|improve this answer edited Jun 1 '12 at 13:27 palacsint 16.3k55080 answered Jun 24 '11 at 21:07 Eric 715415 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Em
