Generate image from url. Not working with aspx page?
<p>I'm trying to produce a report using c#.
First part of the report gets a visual image of a lot (using Mapguide) and places it in a PDF This part works fine.</p>

<p>Next part requires converting a dynamic web page to an image to be inserted into the PDF.
The problem is I have no control over how the webpage is created it seems to be produced as part of a webservice or an ASPX page (http://nautilus/maint_responsibility/rpt_summary.aspx?lease_code=TL01306)</p>

<p>The application hangs while trying to produce an image from the above url :(
This is the class im using</p>

<pre><code>using System.Drawing;
using System.Drawing.Imaging;

using System.Windows.Forms;

public class WebsiteToImage
{
    private Bitmap m_Bitmap;
    private string m_Url;
    private string m_FileName = string.Empty;

    public WebsiteToImage(string url)
    {
        // Without file 
        m_Url = url;
    }

    public WebsiteToImage(string url, string fileName)
    {
        // With file 
        m_Url = url;
        m_FileName = fileName;
    }

    public Bitmap Generate()
    {
        // Thread 
        var m_thread = new Thread(_Generate);
        m_thread.SetApartmentState(ApartmentState.STA);
        m_thread.Start();
        m_thread.Join();
        return m_Bitmap;
    }

    private void _Generate()
    {
        var browser = new WebBrowser { ScrollBarsEnabled = false };
        browser.Navigate(m_Url);
        browser.DocumentCompleted += WebBrowser_DocumentCompleted;

        while (browser.ReadyState != WebBrowserReadyState.Complete)
        {
            Application.DoEvents();
        }

        browser.Dispose();
    }

    private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        // Capture 
        var browser = (WebBrowser)sender;
        browser.ClientSize = new Size(browser.Document.Body.ScrollRectangle.Width, browser.Document.Body.ScrollRectangle.Bottom);
        browser.ScrollBarsEnabled = false;
        m_Bitmap = new Bitmap(browser.Document.Body.ScrollRectangle.Width, browser.Document.Body.ScrollRectangle.Bottom);
        browser.BringToFront();
        browser.DrawToBitmap(m_Bitmap, browser.Bounds);

        // Save as file? 
        if (m_FileName.Length &gt; 0)
        {
            // Save 
            m_Bitmap.SaveJPG100(m_FileName);
        }
    }
}

public static class BitmapExtensions
{
    public static void SaveJPG100(this Bitmap bmp, string filename)
    {
        var encoderParameters = new EncoderParameters(1);
        encoderParameters.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L);
        bmp.Save(filename, GetEncoder(ImageFormat.Jpeg), encoderParameters);
    }

    public static void SaveJPG100(this Bitmap bmp, Stream stream)
    {
        var encoderParameters = new EncoderParameters(1);
        encoderParameters.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L);
        bmp.Save(stream, GetEncoder(ImageFormat.Jpeg), encoderParameters);
    }

    public static ImageCodecInfo GetEncoder(ImageFormat format)
    {
        var codecs = ImageCodecInfo.GetImageDecoders();

        foreach (var codec in codecs)
        {
            if (codec.FormatID == format.Guid)
            {
                return codec;
            }
        }

        // Return 
        return null;
    }
}
</code></pre>

<p>This is the part that generates the image.</p>

<pre><code>WebsiteToImage w = new WebsiteToImage("http://nautilus/maint_responsibility/rpt_summary.aspx?lease_code=TL01306");

MemoryStream myMemoryStream = new MemoryStream();
w.Generate().Save(myMemoryStream, System.Drawing.Imaging.ImageFormat.Jpeg);
</code></pre>

<p>If its changed to <a href="http://www.google.com.au" rel="nofollow">http://www.google.com.au</a> or another application in house it works .... realy struggling to figure this out</p>
