How to read current active IE window's html content

How to read current active IE window's html content

• Samurai Sjakkie

  I do have this working with a BandObject.

  Jumping thru a few hoops....it basically takes this:

  With the BandObject it has an event called Explorer Attached.

  In Load or whatever...subscribe to attached event:

  this.ExplorerAttached += new EventHandler(MyBandObjectToolbar_ExplorerAttached);

  private void MyBandObjectToolbar_ExplorerAttached(object sender, EventArgs e)

  {

  //In this event subscribe to DocComplete

  Explorer.DocumentComplete += new SHDocVw.DWebBrowserEvents2_DocumentCompleteEventHandler(Explorer_DocumentComplete);

  }

  void Explorer_DocumentComplete(object pDisp, ref object URL)

  {

  //Needed to get the current tab HTML

  textBox1.Text = GetTabHtml(URL.ToString());

  }

  public static string GetTabHtml(string theUrl)

  {

  string tabHtml = "";

  foreach (SHDocVw.WebBrowser tab in shellWindows)

  {

  if(theUrl == tab.LocationURL)

  {

  HTMLDocument currentTab = tab.Document as mshtml.HTMLDocument;

  tabHtml = currentTab.body.outerHTML;

  }

  }

  return tabHtml;

  }

  Hi,

   

  I think I got it:) thanks.. however.. how do I install it to IE

  I got this..

   

  Performing Post-Build Event...
  Microsoft (R) .NET Global Assembly Cache Utility. Version 2.0.50727.42
  Copyright (c) Microsoft Corporation. All rights reserved.
  Assembly successfully added to the cache
  Microsoft (R) .NET Framework Assembly Registration Utility 2.0.50727.42
  Copyright (C) Microsoft Corporation 1998-2004. All rights reserved.
  Types registered successfully
  

  so it's okay... but what to do now 

  I noticed that when I rightclick the IE bar it's actually there.. but when I mark it nothing happens..

  Hi ahmedilyas,

  No it's not the webbrowser component in C#:-)
  It is the open website in Internet Explorer 7.0

  The last active page which has been opened IE 7.0

  Do you have a workaround for this

  I hope so... there is absolutly nothing on this when searching google other then what I have fount which doesn't work:(

  okay... I have almost fixed it!!

  You can se the code below.. however.. there is one little thing that is still not working:-(
  I the foreground window has tabs and you are viewing tab nr. 1,2 or 3 out of 4 tabs ect.. you will always get the content of tab number 4..

  any tweak for this By the way I used the win32 api function GetForegroundWindow()
  

  foreach (SHDocVw.WebBrowser ie in shellWindows)

  {

  HTMLDocument doc = ie.Document as mshtml.HTMLDocument;

  if(doc != null )

  {

  IntPtr activeHwnd = GetForegroundWindow();

  if (ie.HWND == activeHwnd.ToInt32())

  {

  richTextBox1.Text = doc.body.outerHTML;

  }

  }

  }

  }

  hmm actually this code is weird:S

  I think I AM on the active tab because when I call refresh it refreshes the page!
  But the innertext gives med the inner text for the last opened tab:S
  
  

  richTextBox1.Text = doc.body.outerHTML; --->wrong tab!

  ie.Refresh(); --- > correct tab!

  so if it is not outerHTML what is it

  foreach (SHDocVw.WebBrowser ie in shellWindows)

  {

  HTMLDocument doc = ie.Document as mshtml.HTMLDocument;

  IntPtr activeHwnd = GetForegroundWindow();

  if(doc != null )

  {

  if (ie.HWND == activeHwnd.ToInt32())

  {

  richTextBox1.Text = doc.body.outerHTML;

  ie.Refresh();

  }

  }

  }

  Are you creating a BandObject (using the codeproject example)..

  More than likely a pop-up....or javascript window...

  I have a half-assed pop up blocker....it works on that page.

  if you use a webbrowser control, you can read the html document on the page in the document_completed event and look at the DocumentText property, this will give you the entire page as is in Html, the html code for the page

  is this not what you are after

  try:

  if(ie.HWND != 0)

  //get doc

  Hi again,

  No I am using your code as "stand-alone"
  However I modified it a little so I could get the last active window, but there is one last issue and that is that I get the last opened TAB inside of this IE window and not the one that the user is active in.

  I don't know.. I tried to find a win32 api function for i:S

  If it can be done with the BandObject it's fine with me... I see that it has a get UrlLocation, but it's not implemented

  not sure, but it's not showing up when I create an instance of the BandObject:(

  No I have it included in a much larger shareware project. sorry.

  That code works fine. Just add those events to the Bandobject example.
