How can I export a .ppt file as .pptx? I tried using presentation.Save(stream, Aspose.Slides.Export.SaveFormat.Pptx); but I get an error saying “This export format is not implemented for PPT yet.”.
We regret to inform you that currently feature of exporting a PPT presentation to PPTX is unavailable. An Issue with ID 13419 has already been created in our Issue Tracking System to look in to the possibility of the feature. This thread is also associated with this issue, so that you can automatically notified when the issue is resolved.
I regret to share that the support for PPT export to PPTX and vice versa has not yet been available in Aspose.Slides for .NET. We are hopeful that support may be available in winter release of Aspose.Slides for .NET but unfortunately, we are unable to make any promises.
Please proceed to this documentation link for list of supported features in PPT to PPTX conversion at the moment. Unfortunately, I may not share the exact version in which full support will be available. The features will be added in upcoming subsequent releases of Aspose.Slides for .NET.
I am trying to open a pptx file in a documentviewer control in wpf
Presentation pres = new Presentation(open_filedialog.FileName.ToString()); when i try to open a pptx file using the above code, following error msg is displayed.
{“The file is ZIP archive. It can be Microsoft PowerPoint 2007 PPTX presentation.”}
Please use the following code snippet to open the PPTX file with protection. Unfortunately, the PPT protection is currently unavailable in Aspose.Slides for .NET. Please use the following code snippet to open password protected PPTX.
