I have a Presentation created in 2007 saved as .ppt. It has a slide where I modify a table to add columns and text and then write to file. Upon opening file in 2007 none of the new columns or text appear however if I open the same file in older PowerPoint the changes are there. Also if I savetoPDF the changes are there also.
I am using the latest version just downloaded yesterday and installed. Any guidance on how to get around this would be appreciated.
Probably you created this ppt file with old version of Aspose.Slides for .NET because simple opening and resaving this presentation using latest version solves the problem and slide looks similar in both PowerPoint 2003 and 2007.
I published new version today in this thread so you can use it.
