Read Webbrowser content having hwnd of the window

Posted on 2009-07-09
Last Modified: 2012-05-07
When I search for the child windows I get:
ID: 0, ClassName: Static, Caption:
ID: 0, ClassName: Shell Embedding, Caption:
ID: 0, ClassName: Shell DocObject View, Caption:
ID: 0, ClassName: Internet Explorer_Server, Caption:

What I know is that there is a webbrowser withing the application. How can I have access to the application webbrowser content?

I have the hwnd of the application window. How do I go from here for getting the webbrowser content including the url it is taking the info from.

You don't need to use the handle, you can use the ShellWindows to check for the instance of IE you want to
get the doc from by using the code below.
uses ..., ShellAPI, ShDocvw, MSHTML;


  ShellWindow: IShellWindows;

  WB: IWebbrowser2;

  spDisp: IDispatch;

  IDoc1: IHTMLDocument2;

  k: Integer;


  ShellWindow := CoShellWindows.Create;

  // get the running instance of Internet Explorer

  for k := 0 to ShellWindow.Count do


    spDisp := ShellWindow.Item(k);

    if spDisp = nil then Continue;

    // QueryInterface determines if an interface can be used with an object

    spDisp.QueryInterface(IWebbrowser2, WB);

    if WB <> nil then


      WB.Document.QueryInterface(IHTMLDocument2, iDoc1);

      // You now have the HTML document in the iDoc variable...

      if iDoc1.Title = 'Read Webbrowser content having hwnd of the window' then


        // This page matched the title that I wanted

Well, that won't work for an application that just has an embedded webbrowser. Let me take a closer look.

1) Find the webbrowser handle by enumerating the child windows of that window
2) Retrieve IWebbrowser2 from it (search for GetIEFromHWND)
3) Get IHTMLDocument2 from it to access the wb source
