Attachment Viewer 2.0 beta – MS Office Support!

I need some help testing this out. After playing around a little bit with C# and the MS Office integration API’s I was able to compile an executable that calls out to MS Office to show Documents, Presentations, and Spreadsheets. The architecture is pretty straightforward, the attachment viewer calls out to an executable to have the file converted to HTML and then the document is shown in an iframe in the viewer. I have seen some minor issues and thankfully no crashes.

This version is also Dojo enabled and currently needs to have internet access in order for it to work since I pull Dojo 1.5 from the Google CDN. You will notice the Dojo toolbar and the different view modes – Film Strip, Slide Show, Thumbnails:


Installation Instructions:

  • If you have a 1.0 version of the attachment viewer installed, please make sure you uninstall it first.
  • Once you have the older version installed you can drap and drop the icon below to your My Widgets panel to have the new Eclipse plugins installed.

Drag this to My Widgets in Lotus Notes

  • You may also need to set the preference for the viewer under File | Preferences:

Once I get some good feedback I will be posting the binaries and sources to the OpenNTF project.

Some known issues:

  • The thumbnail view does not show the last image as a thumb
  • Sometimes the MS Office link is broken, a restart or shutting down MS Office may be needed.

In advance, thanks for all of your feedback and interest in this project!

  1. Hi Bob,

    Sorry to bring it to you, but the attachment viewer does not show previews of doc, docx, xls or xlsx files in my 8.5.2 client. Did not try PPT.

    It does show images and pdf.

    I did install the MS Office 2007 Interop thing.


  2. Hhm, can you check the preferences, under File | Preferences | Attachment viewer and make sure the Microsoft Office viewer is selected?

    I may have to add that step to the post.

  3. Hello Bob,

    can not install “MS Office 2007 Interop thing” with Office 2010.
    I install MS Office 2010 Interop thing, with no success.


  4. Hi Bob,

    PDF-JPG-ZIP/Files are ok and we can see the attachments but office-xp or office-2010/files, the viewer shows nothing!

    Notes 8.5.2
    Windows XP
    Office xp or Office 2010 (German)


  5. So something must be wrong. I am wondering if this is working for anyone?? The file has over 30 downloads but I am not sure how many are duplicate.

    What you can do to see what’s going on is look for the file officetohtml.exe in the directory C:notesdataworkspaceapplicationseclipsepluginsorg.openntf.attachmentviewer.ms_office_2.0.0.beta

    The parameters for the file are as follows:


    If that works then there must be a problem with the extension. If that does work then I still have a gap in the extension layer (Eclipse side).
