| Post subject: | Adding a pdf to an existing pdf |
My project requires that I create a single pdf and save it in a directory. Then add that pdf to another pdf in a separate directory. Code: Private Sub AddInvoiceToDaily(SingleFile As String, CombinedFile As String) Dim doc1 As PdfDocument = PdfReader.Open(SingleFile, PdfDocumentOpenMode.Import) Dim doc2 As PdfDocument Dim page As PdfPage = doc1.Pages(0) If Not File.Exists(CombinedFile) Then doc2 = doc1 Else doc2 = PdfReader.Open(CombinedFile, PdfDocumentOpenMode.Import) doc2.AddPage(page) End If doc2.Save(CombinedFile) End Sub Regardless of whether the file exists I get this error message: "The document cannot be modified." at "Doc2.save(CombinedFile). Any help would be greatly appreciated. Brad |
