Differences between PPT and PPTX file handling in new .NET version of Slides

Aspose.Slides Product Family

I just finished changing some of our code to handle the new OM for Aspose.Slides 14.2.0.0, and I’ve noticed that a few things are different between how PPT and PPTX files are handled.



I’ve attached two version of the same file to this post, one saved as a PPT file and one as a PPTX. If you place them in the same directory and run the following code on them (replace “[PATHTOFILES]” with the directory name), you’ll see that the results are different:



Dim SourceFile = “[PATHTOFILES]\Test File.ppt”



Dim Presentation = New Aspose.Slides.Presentation(SourceFile)



Dim Result = New System.Text.StringBuilder



Result.AppendLine(String.Format(“There are {0} custom document properties in this document”, Presentation.DocumentProperties.Count))

Result.AppendLine(String.Format(“Slide 2 has {0} comments”, Presentation.Slides(1).GetSlideComments(Nothing).Count))

Result.AppendLine(String.Format(“Slide 3 {0} hidden”, If(Presentation.Slides(2).Hidden, “is”, “is not”)))



MessageBox.Show(Result.ToString)



Presentation = New Aspose.Slides.Presentation(SourceFile & “x”)



Result = New System.Text.StringBuilder



Result.AppendLine(String.Format(“There are {0} custom document properties in this document”, Presentation.DocumentProperties.Count))

Result.AppendLine(String.Format(“Slide 2 has {0} comments”, Presentation.Slides(1).GetSlideComments(Nothing).Count))

Result.AppendLine(String.Format(“Slide 3 {0} hidden”, If(Presentation.Slides(2).Hidden, “is”, “is not”)))



MessageBox.Show(Result.ToString)



It appears that comments, custom document properties and hidden slides are not being properly handled in the new version of Aspose.Slides. Are these known issues, by any chance? Is there any workaround?



Thanks,
