HTML to PDF on web

[Bashkim Deliu]

Hi,

I keep getting an error what ever I do, while trying to convert an html page.

The code I am using on my web project is:

 PdfDocument pdf = new PdfDocument();

            pdf.PageSettings.SetMargins(0);

            pdf.PageSettings.Orientation = PdfPageOrientation.Portrait;

            pdf.PageSettings.Rotate = PdfPageRotateAngle.RotateAngle0;

            PdfPage page = pdf.Pages.Add();

            PdfUnitConvertor converter = new PdfUnitConvertor();

            float width = converter.ConvertToPixels(page.GetClientSize().Width, PdfGraphicsUnit.Point);

            try

            {

                using (HtmlConverter html = new HtmlConverter())

                {

                    html.EnableJavaScript = true;

                    html.AutoDetectPageBreak = true;

                    html.EnableHyperlinks = true;

                    HtmlToPdfResult result = html.Convert("http://www.syncfusion.com", ImageType.Metafile, (int)width, -1, AspectRatio.KeepWidth);

                    if (result != null)

                    {

                        PdfMetafile mf = new PdfMetafile(result.RenderedImage as Metafile);

                        mf.Quality = 100;

                        PdfMetafileLayoutFormat format = new PdfMetafileLayoutFormat();

                        format.Break = PdfLayoutBreakType.FitPage;

                        format.Layout = PdfLayoutType.Paginate;

                        pdf.PageSettings.Height = result.RenderedImage.Size.Height;

                        format.SplitTextLines = false;

                        format.SplitImages = true;

                        result.Render(page, format);

                    }

                    else

                    {

                        Response.Write("Warning! Please check the HTML link");

                    }

                    pdf.Save("Sample.pdf", Response, HttpReadType.Save);

                }

            }

            catch (Exception exeption)

            {

                string message = exeption.Message;

                Response.Write(exeption);

            }

I did reference Syncfusion.HTML.Convert.Base and Syncfusion.HTML.Pdf.Base 

 And this an error I am getting.

System.Threading.ThreadStateException: ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment. at System.Windows.Forms.AxHost..ctor(String clsid, Int32 flags) at Syncfusion.HtmlConverter.Natives.AxWebBrowser..ctor() at Syncfusion.HtmlConverter.HtmlConverter.InitializeControl() at Syncfusion.HtmlConverter.HtmlConverter..ctor()

Am I missing anything?

Thank you in advance for your attention.

I got this same error. I solved it by running the code that create the pdf in a new thread.

You need to make sure you set the ApartmenetState of the new Thread to STA
