Hi, I've followed the basic example code here:


Code: Visual Basic.NET
'Load the file
Dim doc As New PdfDocument(pdfFileName)

'Append a new page
Dim page As PdfPage = doc.Pages.Add()

'Render contents on the new page
HtmlToPdf.ConvertHtml("Text on the new page.", page)

'Save it to a new file
doc.Save(newFileName)


When this code trys to run the line: HtmlToPdf.ConvertHtml("Text on the new page.", page)

I get the following error:
An exception of type 'EO.Pdf.HtmlToPdfException' occurred in [...dll] but was not handled in user code

Additional information: Conversion failed. Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

Why would this simple code not work?

Hi,

We tested your code here and it works fine here. So the issue might have to do with the existing PDF file that you are trying to load. You can send us the PDF file in question and we will be happy to look into it and see what we can find. See here for more information on how to send test file to us:

Hi,

We tested your file with your code here and it still works fine. What version do you use? Can you try the latest build and see if it works for you?

Thanks!

Hi, this has been resolved as of yesterday. There was a line of code blocking access to the local file system which was causing the error.

Thanks
