PPT File : Aspose.ISlide.Hidden property always returns False Version 14.3.0

Aspose.Slides Product Family

Hi Support,

I am trying to determine which slides are hidden or not in a presentation. With the latest version I found out that the Hidden property is always false for PPT files.

Sample Code

var ppt = new Presentation("Slides.ppt");
var hiddenSlidePpt = ppt.Slides[1];
Trace.WriteLine("PPt hidden property: " + hiddenSlidePpt.Hidden);

var pptx = new Presentation("Slides.ppt");
var hiddenSlidePptx = pptx.Slides[1];
Trace.WriteLine("PPtx hidden property: " + hiddenSlidePptx.Hidden);

Output

PPt hidden property: False
PPtx hidden property: True

Please find attached Slide.ppt and Slide.pptx the files used for my tests. The second slide of each of these files is hidden.

Thank you,
Lea

I am experiencing the same issue using version Aspose.Slides 14.7.0.0

Is there any update or resolution for this?

Perhaps this is unrelated, but I notice that when I instantiate a Presentation object from an existing .ppt format document, the Presentation.FileExtension property = “.pptx”. This happens even if I explicitly use Aspose.Slides.LoadFormat.Ppt

Hi Lea,

Thanks for sharing your feedback. I request you to please share the sample presentation and code sample used for your verification. I will investigate it further on my end to help you out.

Dim fi As New FileInfo(filename)
Dim loadopts As New Aspose.Slides.LoadOptions()

If fi.Extension.Equals(".ppt", StringComparison.OrdinalIgnoreCase) Then
    loadopts.LoadFormat = Aspose.Slides.LoadFormat.Ppt
ElseIf fi.Extension.Equals(".pptx", StringComparison.OrdinalIgnoreCase) Then
    loadopts.LoadFormat = Aspose.Slides.LoadFormat.Pptx
End If

pres1 = New Presentation(filename, loadopts)

pres1.FileExtension is always “.pptx” when I open a .ppt source file

Hi Lea,

I have observed the sample code shared by you but unfortunately the requested source presentation creating issue on your end is still missing. However, I have tried loading a PPT on my end and then used the following sample code to get the source format. It gave me PPT for a PPT source format presentation.

pres.SourceFormat

Please try using the above property and if there is still an issue then please share a sample project and sample presentation reproducing the issue on your end so that I may help you further in this regard.

Many Thanks,
