Hi,

Why is the following code not working?

Dim parentbookmark As New Aspose.Pdf.Kit.BookMark

Dim childbookmark As New Aspose.Pdf.Kit.BookMark

parentbookmark.PageNumber = 1

parentbookmark.Title = "Parent"

childbookmark.PageNumber = 2

childbookmark.Title = "Child"

parentbookmark.ChildItem.Add(childbookmark)

'after the last line I get an NullReferenceExeption, but why?

Thanks,

Daniel

Hi Daniel,

Thank you very much for considering Aspose.

I have tried the following code snippet and it worked perfectly fine at my end.


Dim editor As New Aspose.Pdf.Kit.PdfBookMarkEditor

editor.BindPdf(“input.pdf”)


Dim parentbookmark As New Aspose.Pdf.Kit.BookMark

Dim childbookmark As New Aspose.Pdf.Kit.BookMark


parentbookmark.PageNumber = 1

parentbookmark.Title = “Parent”


childbookmark.PageNumber = 2

childbookmark.Title = “Child”


Dim bms As New Aspose.Pdf.Kit.BookMarks()

bms.Add(childbookmark)



parentbookmark.ChildItem = bms


editor.CreateBookmarks(parentbookmark)

editor.Save(“output.pdf”)




Please try this at your end. In case, you find any further questions, or have some issue please do let us know.
