Embedding a pdf or image as an icon in presentation using Aspose.Slides for .NET

I am trying to embed more files in presentation slide as icon object in c#:

string sOleClassName = string.Empty;
case “.pdf”: sOleClassName = “AcroExch.Document.DC”; break;
case “.docx”:
case “.doc”: sOleClassName = “Word.Document.12”; break;

byte[] allbytes = System.IO.File.ReadAllBytes(sFilePath);
IOleObjectFrame oof = newSlide.Shapes.AddOleObjectFrame(x, y, w, h, sOleClassName, allbytes);
oof.IsObjectIcon = true;

For word and excel it works while for pdf, image, etc … i have this error:

“The server application, source file, or item can’t be found, or returned an unknown error. You may need to reinstall the server application.”

What can I do ?


I have observed the issue shared by you and suggest you to please first try using latest Aspose.Slides 18.8 on your end. If there is still an issue then please provide the working sample code along with source files and generated presentation reproducing the issue on your end.

My code (not work with Aspose.Slides 18.8):

      Presentation pres = new Presentation("test.pptx");
      ISlide slide = pres.Slides[0];

      //Add Ole objects
      byte[] allbytes = System.IO.File.ReadAllBytes("test.pdf");
      IOleObjectFrame oof = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, "AcroExch.Document.DC", allbytes);
      oof.AlternativeText = "PDF";
      oof.IsObjectIcon = true;

      allbytes = System.IO.File.ReadAllBytes("test.docx");
      oof = slide.Shapes.AddOleObjectFrame(20, 120, 50, 50, "Word.Document.12", allbytes);
      oof.AlternativeText = "WORD";
      oof.IsObjectIcon = true;

      allbytes = System.IO.File.ReadAllBytes("test.xlsx");
      oof = slide.Shapes.AddOleObjectFrame(20, 220, 50, 50, "Excel.Sheet.12", allbytes);
      oof.AlternativeText = "EXCEL";
      oof.IsObjectIcon = true;

      allbytes = System.IO.File.ReadAllBytes("test.jpg");
      oof = slide.Shapes.AddOleObjectFrame(20, 320, 50, 50, "Paint.Picture", allbytes);
      oof.AlternativeText = "JPEG";
      oof.IsObjectIcon = true;

      pres.Save("testsaved.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
