Take a full webpage screenshot opened in running instance of Internet Exploler

Question

Hi everyone.
I'm trying to get a full webpage screenshot opened in running instance of Internet Exploler, but I get an empty image as a result. Here is my code:
foreach (SHDocVw.InternetExplorer web in shellWindows)
mshtml.IHTMLDocument2 docs2 =(mshtml.IHTMLDocument2)web.Document;
mshtml.IHTMLDocument3 docs3 = (mshtml.IHTMLDocument3)web.Document;
mshtml.IHTMLElement2 body2 = (mshtml.IHTMLElement2)docs2.body;
mshtml.IHTMLElement2 root2 = (mshtml.IHTMLElement2)docs3.documentElement;
int width = Math.Max(body2.scrollWidth, root2.scrollWidth);
int height = Math.Max(root2.scrollHeight, body2.scrollHeight);
Rectangle docRectangle = new Rectangle(0, 0, width, height);
web.Width = docRectangle.Width;
web.Height = docRectangle.Height;
Rectangle imgRectangle;
if (imgsize == null) imgRectangle = docRectangle;
else imgRectangle = new Rectangle() { Location = new Point(0, 0), Size = imgsize.Value };
Bitmap bitmap = new Bitmap(imgRectangle.Width, imgRectangle.Height);
IViewObject ivo = web.Document as IViewObject;
var type = web.Document.ToString();
using (Graphics g = Graphics.FromImage(bitmap))
IntPtr hdc = g.GetHdc();
ivo.Draw(1, -1, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, hdc, ref imgRectangle, ref docRectangle, IntPtr.Zero, 0);
g.ReleaseHdc(hdc);
bitmap.Save("D:\\1.bmp");
bitmap.Dispose();
Could you please advise me, what I did wrong? 
Maybe there exist some other way to do it?
Thanks for help!

Hi ya_roslav,
I think a simple method is to get a screenshot( because your IE frame is actived).
If you could get the screenshot bitmap, then you could delete the pixels out of IE frame based on the IE frame start position and its width and height.
