Hello,

Thanks for your inquiry.
The “oleObject.ProgId” is related to the PDF document reader installed on your system. You can refer to the following code to meet your requirement.

Code: Select all
            //oleObject.ProgId = "package";
            //oleObject.ProgId = "AcroExch.Document.DC";
            oleObject.ProgId = "Acrobat.Document.DC";

If this doesn't work for you, please provide your test PPT file for further investigation. You could send it to us via email (support@e-iceblue.com). Thanks in advance.

Sincerely,
Brian

Hello,

Thanks for providing your input file via email.
After further analysis, I found that the progid for the PDF oleobject in your document is “AcroExch.Document.DC”. Please refer to the following code to access the PDF oleobject and download the latest Spire.Presentation Pack Hotfix Version:6.6.6 for testing. If there is any question, just feel free to contact us.
Code: Select all
            Presentation presentation = new Presentation();
            presentation.LoadFromFile("pdfoleidnotopening.pptx");

            int i = 0;
            foreach (ISlide slide in presentation.Slides)
            {
                foreach (IShape shape in slide.Shapes)
                {
                    if (shape is IOleObject)
                    {
                        IOleObject oleObject = shape as IOleObject;

                        byte[] bytes = oleObject.Data;
                        string progId = oleObject.ProgId;
                        switch (oleObject.ProgId)
                        {
                            case "Acrobat.Document.DC":
                                File.WriteAllBytes("resultAcrobat" + i+".pdf", bytes);
                                break;
                            case "AcroExch.Document.DC":
                                File.WriteAllBytes("resultAcroExch" + i+".pdf", bytes);
                                break;
                            case "package":
                                File.WriteAllBytes("resultpackage" + i+".pdf", bytes);
                                break;                               
                        }
                        i++;
                    }
                }
            }
