Hi,
I'm trying to take a screenshot of some different webpages, but I need to resize my webbrowser control to fit the web page before using DrawToBitmap to create the image.

My code is

WebBrowser wb = new WebBrowser();
wb.ScrollBarsEnabled = false;
wb.ScriptErrorsSuppressed = true;
wb.Navigate(url);
while (wb.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); }  
Bitmap bitmap = new Bitmap(wb.Width, wb.Height);
wb.DrawToBitmap(bitmap, new Rectangle(0, 0, wb.Width, wb.Height));
return bitmap;

Open in new window


I've tried various combinations of

Document.Window.Size
Document.Body.Document.Window.Size.Width

Open in new window


but it still chops bits off the sides and bottom.

Thanks

I don't think its the Document object that you should be looking at - I would think that is referring to the client-side element.  Try setting the height and width of the WebBrowser control.

WebBrowser wb = new WebBrowser();
wb.ScrollBarsEnabled = false;
wb.ScriptErrorsSuppressed = true;
wb.Width = 1024;
wb.Height = 768;
wb.Navigate(url);
while (wb.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); }  
Bitmap bitmap = new Bitmap(wb.Width, wb.Height);
wb.DrawToBitmap(bitmap, new Rectangle(0, 0, wb.Width, wb.Height));
return bitmap;

Open in new window

I am, but it needs to resize itself according to the size of content in order to take the screenshot of the entire page

Well, here's the problem... unless the page is assigned a height and width, some browsers aren't able to "see" the computed height and width.  You'd have to make sure that each page is assigned a height and width... even then it could be flaky.
