Error 8 ‘System.Web.HttpApplicationState’ does not contain a definition for ‘DoEvents’

Doevents will work in a project but not a web application apprarantely. Did I miss something? How can I get it to work in my website application?

public Bitmap GenerateScreenshot(string url, int width, int height)
{
// Load the webpage into a WebBrowser control
WebBrowser wb = new WebBrowser();
wb.ScrollBarsEnabled = false;
wb.ScriptErrorsSuppressed = true;
wb.Navigate(url);
while (wb.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); }

// Set the size of the WebBrowser control
wb.Width = width;
wb.Height = height;

if (width == -1)
{
// Take Screenshot of the web pages full width
wb.Width = wb.Document.Body.ScrollRectangle.Width;
}

if (height == -1)
{
// Take Screenshot of the web pages full height
wb.Height = wb.Document.Body.ScrollRectangle.Height;
}

// Get a Bitmap representation of the webpage as it’s rendered in the WebBrowser control
Bitmap bitmap = new Bitmap(wb.Width, wb.Height);
wb.DrawToBitmap(bitmap, new Rectangle(0, 0, wb.Width, wb.Height));
wb.Dispose();

return bitmap;
}

}

More details on this and my version of the code can be read at http://blackbeltcoder.com/Articles/asp/creating-website-thumbnails-in-asp-net.

Great code, it’s working on many sites but on mine only the left part is rendered, do you know why ? Thanks.

The application should be waiting before the browser reports that the page is finished loading. agreed that might not be enough if the loading is in a plugin’s space. You can pretty easily modify the application to wait a certain timeout before taking the screenshot and after the browser reports loading completion.

If that is not something that you can do yourself (not being programmer maybe?) mail me and I will compile a custom version of the app for you. You can find my mail on the “About me” page.
