Support,

Occasionally we get the following errors when generating web pages using EO.pdf:

System.IO.IOException: The handle is invalid.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.WriteCore(Byte[] buffer, Int32 offset, Int32 count)
at System.IO.FileStream.Write(Byte[] array, Int32 offset, Int32 count) at EO.Pdf.Internal.b4.a(Stream A_0)
at EO.Pdf.Internal.hh.a(Stream A_0)
at EO.Pdf.Internal.hh.b(String A_0)
at ARRT.Utilities.PDFutil.GenerateConfPagePDF(String html, String filename, Boolean resize, Boolean removeImages)
at Renewal_Confirmation.Page_Load(Object sender, EventArgs e)

Could you tell us how to stop these errors from occurring?

Using EO.PDF version 4.0.41.2

Thanks!

Thanks, one last question.

If it's because the stream object has been closed, why would that be?

Is the scenario when someone lets the page partially load and they close out their browser?

We are not ending the stream, so what causes the stream to close or dispose before it's done?

Here is the code.

We don't specifically have any stream objects. Just an HTML string we pass to this:

HtmlToPdfOptions options = new HtmlToPdfOptions();
if (resize)
options.ZoomLevel = 0.8f;
options.NoLink = true;
options.NoScript = true;
options.NoCache = true;
options.PageSize = PdfPageSizes.A4;
PdfDocument doc = new PdfDocument();
doc.EmbedFont = false;
HtmlToPdf.ConvertHtml(html, doc, options);

It looks like the last line HtmlToPdf.ConvertHtml(html,doc,options) is actually what calls: EO.Pdf.Internal.hh.b(String A_0)

It is in the first post of this message, or where you looking for something else?

The ARRT.Utilities.PDFutil.GenerateConfPagePDF code contains the code I posted on Feb 27 @ 4:17PM:

HtmlToPdfOptions options = new HtmlToPdfOptions();
if (resize)
options.ZoomLevel = 0.8f;
.....
.....

Let me know what else you need.
