Hi there, We use EO.pdf to render conference badges, and on each badge is a barcode image. The html that is generated is essentially a div for each badge with the same content. The image tag in question is: Quote:<img src="BarcodeGen.ashx?code=7107263^]Mr.^!Trowa^!Barton^Pilot^Heavy%20Arms^12629%20Riverside%20Dr^^Denver^Colorado^91607^United%20States^123-123-1234^^^22924&&barwidth=0.01&cType=Auto&ratio=2&rows=0&columns=0&tMargin=0.01&bMargin=0.01&sym=Pdf417&cTruncated=false&width=2&height=0.5&dpi=72&AspxAutoDetectCookieSupport=1&encrypt=true" pdf417=""> Now this works fine after the first 3, but I cant seem to figure out why this is the case. My render code is straitforward: Quote:HtmlToPdf.Options.NoScript = false;
HtmlToPdf.Options.MaxLoadWaitTime = Int32.MaxValue;
using (var ms = new MemoryStream())
{
HtmlToPdf.ConvertUrl(url, ms);
ms.Seek(0, SeekOrigin.Begin);
return ms.ToArray();
} I've also tested the html and I am able to view the images properly for the entire document when I render it with chrome/firefox. Thanks for your help!

Hi,
Please check whether you are rendering pages on the same server. For example, if your application has two pages, Page1.aspx and Page2.aspx, and inside Page1.aspx (for example, when a button is clicked) you call ConvertUrl to convert Page2.aspx. In this case, you would be calling ConvertUrl back to the same server. This can easily run into ASP.NET session lock issue. If this is the case, please try to use ASPXToPDF to render the page.
If that's not the problem, then you can either check your IIS log or use a Web traffic monitor (for example, fiddler) to monitor the web traffic when this occurs. This should allow you to see whether an image was indeed returned by the web server, and if not, what's the error code. That might give you some pointers.
Hope this helps. Please feel free to let us know if you still have any questions.
Thanks!
