| Post subject: | Unable to open PDF after creating with PDF Sharp |
Hello, I get the following message when I attempt to open a PDF that I created with the attached code I got from here. "Adobe Acrobat could not open "name of file", because it is either not a supported file type or has been damaged..." I am unable to open from Windows Explorer directly or through my application. The file does open using the Process.Start method as in the code, but the program is just to create for later use so the Start.Process was left in temporarily. The PDF is shown as 0 KB even though there is a page and name added using this code. Do I need to add more? Here is the code: Note: sWorkerFolder is a path to the file and the file name is entered by the user in a text field. Dim newPDF As New Pdf.PdfDocument newPDF.Info.Title = txtPDFFileName.Text.Trim Dim page As Pdf.PdfPage = newPDF.AddPage Dim gfx As XGraphics = XGraphics.FromPdfPage(page) Dim pen As XPen = New XPen(XColor.FromArgb(255, 0, 0)) Dim font As XFont = New XFont("Verdana", 20, XFontStyle.Bold) ' Draw the text gfx.DrawString("Hello, " & Environment.UserName & "!", font, XBrushes.Black, New XRect(0, 0, page.Width.Point, page.Height.Point), XStringFormats.Center) ' Save the document... Dim sFileName As String = sWorkFolder & txtPDFFileName.Text.Trim & " WC.pdf" newPDF.Save(sFileName) Process.Start(sFileName) |

A PDF created by PDFsharp containing the text "Hello" should be larger than 1 kB, so seeing 0 kB looks definitely wrong.To me it is a bit unclear what you do and when the error occurs. |

The code works to generate a PDF and if I leave the Process.Start(filename) code in place the file opens and looks good. However, after I close the file and then go back to view it, the error message I provided is displayed when Acrobat opens. The PDF I created does not reappear. Is the Save() method from PdfDocument not working properly? I don't think that is the issue, but I not sure why the only bit of code I found online to use PDFSharp to create a PDF is not working. |

I found that I am able to create the file and access it as long as I leave it in the location where it is created. The File.Copy command, not related to PdfSharp is where the issue resides. The copy is somehow corrupting the file. |
