Hi,

Please try to set this property:

http://www.essentialobjects.com/doc/eo.pdf.htmltopdfoptions.certificateerror.aspx

Inside the handler you would call e.Continue to ignore the certificate error.

Thanks!

Hi,

Could you please let us know how to use this?
If you could provide a sample code in VB.NET that will be great.

Regards,
Anurag

Hi,

The code will be something like this:

Call this before the conversion:

Code: Visual Basic.NET 
'Set custom certificate error handler
HtmlToPdf.Options.CertificateError = AddressOf OnCertificateError


And the handler:

Code: Visual Basic.NET 
Private Shared Sub OnCertificateError(sender As Object, e As EO.WebBrowser.CertificateErrorEventArgs)
    'Ignore the certificate error and continue
    e.Continue()
End Sub


Thanks!

@eo_support - I am using EO.PDF with a file version of 16.0.78. I am now getting this error in one of my client's environment. Based on your comment, the solution is to provide a code fix, which i like to avoid. Can you please explain why this happens only on one environment and not on any others. I have been using this component for several years now and i don't remember anything like this have happened before.

Hi,

This particular error has to do with certificate verification. There are many reasons that can cause certificate verification to fail ---- for example, you may not have installed the specific root trusted certificated on your system, and older version of Chromium browser engine has issue with certain certificates. Whatever the reason maybe, the code in the previous posts would instruct the browser engine to ignore such errors and continue with the SSL connection.

If you still have issues, you should consider updating to the latest version. That will eliminate the Chromium browser engine issue mentioned earlier, and it will also entitle you for additional tech support. We provide free tech support for one year only, so if your version is 16 and you have not updated, then the support period for you in fact has already expired.

Thanks!

Thanks for your quick response. After checking with concerned people, i can conform that we do have an active/latest license for your latest product. We just have not updated yet. As a quick fix, instead of updating the library, we have decided to handle 'CertificateError' as you have recommended earlier, but i am not able to fine `CertificateError` in `HtmlToPdf.Options`. Has that been moved to some other namespace? if it is moved, a one line example of using that would be great! In case if you are interested, this is what i am using today

pdfOptions.NoScript = true;
pdfOptions.AllowLocalAccess = false;
pdfOptions.MaxLoadWaitTime = (int)TimeSpan.FromMinutes(1).TotalMilliseconds;
pdfOptions.NoCache = true;
pdfOptions.NoLink = true;
HtmlToPdf.ConvertHtml(html, fileFullPath, pdfOptions);

Thanks,
James
