Hello i'm currently using aspose.pdf 3.6.1.0 to create a survey.
when opening the document with adobe 6.0 i get this error message:
there was an error opening this document. the file is damaged and could not be repaired.
The file is viewable in both foxit and adobe reader 8.xx
I have attached the document.
Below is my code which basically adds images to the pdf document.
void ibPDF_Click(object sender, ImageClickEventArgs e)
{
survey.ViewMode = SurveyViewMode.PDF;
Pdf pdfPresentation = new Pdf();

{
if (sch.Active)
{
addTable();
foreach (Question q in sch.Questions)
{
if (q.IsActive)
{
// kjører teller på nominal group for å kunne skille med even og odd
if (q.ProductID == 1 || q.ProductID == 6)
{
NominalGroupNumber++;
if (NominalGroupNumber % 2 == 1)
q.Odd = true;
}
addQuestion(q);
}
}
}
}

addEndSpace(tableHeight, survey.addins.HasAddin(2));
