PPTX Export Creates File That Appears Corrupted When Opening With PowerPoint 2007 but not PowerPoint 2010

[Charles Rosecrans, Jr.]

We have recently added the feature to create PPTX and XLSX files to our report exports.  We've found a problem with the PowerPoint PPTX export using the new Open XML 2.0 SDK libraries:  when opening the files up, PowerPoint 2007 complains about the file saying it is "unable to display some of the text, images or objects on slides...because they have become corrupted".  In PowerPoint 2010, the file opens and displays without any complaints.

I had a similar problem in the XLSX file until I realized the we had two or more worksheets with the same name sometimes.  Creating worksheets with unique names with in the file made that problem go away.  Using the Open XML production tools, the PPTX file the reporting engine is creating has no stated problems.  It's only when PowerPoint 2007 tries to open the file that it complains.

Has anyone else seen this type of behavior and been able to find a reason or workaround for it.

Thanks in advance,

Butch Rosecrans

Hello Charles,

Can you reproduce this in our online demos and verify the problem occurs on more than one machine? Since you have tried to open the files with the Open XML SDK tool and it does not report any errors, and the file is opened correctly with the newer MS Office suite, it sounds like contacting MS on that matter and provide them with a problematic file might be a good idea. You can provide us with a report that generates a problematic file so we can look into it as well, but with the info you've given so far, we're not sure we would be able to pinpoint a culprit.

All the best,

Sorry for letting this go dead.  It appears the problem is only when I render a table to a powerpoint 2007 slide so I'm spending time in that area to see what's different.

I assume it's something I'm getting wrong and will update the post once I figure out what it is.

Thanks
