EO.Pdf.Runtime.AddLicense( _ <long license key>)
ASPXToPDF1.RenderAsPDF()
End Sub then i get the following error page: Quote:Unable to cast object of type 'EO.Pdf.HtmlToPdfOptions' to type 'System.IServiceProvider'.

Hi,
That's because your EO.Pdf.dll is too old. Please try to download the latest EO.Pdf from our download page, then copy the new DLL over to your website's bin directory. That should resolve the issue for you.
Thanks!

Hi,
It supposes to render everything exactly the same as your browser. However there are several major browsers and they may render things differently. Our rendering should be most close to Google Chrome and Apple Safari. If you see significant difference between our result and Chrome/Safari, please post a test page and we will be happy to take a look.
Thanks!
