IE7, IE8 Tab Interaction - Accessibility Class

Question

 Here's a C# Class for IE7 + IE8 Tabs (using Accessibility) - no ShellWindows

Tested with XP and IE7 + IE8.

Usage: Add a reference to Accessibility

IEAccessible tabs = new IEAccessible();

var active = tabs.GetActiveTabIndex(yourIEMainHWND);

Methods Available:

GetActiveTabIndex

GetActiveTabCaption

Activate Tab by Index or Caption

GetTabCount

GetTabCaptions

Answer 1

Hi cablehead,

I hope your still watching this thread. I have been able to implement this code in my app and I can see that it will work with IE8 aswell. I haven't tested it with Vista but as it dosen't use shellexecute so it should work. 

I need a method to close a tab with a given tabcaption. I have been trying to sendmessage with WM_CLOSE, WM_DESTROY, WM_QUIT, QM_NOTIFYPARENT etc with no joy. I tried to close TabWindowClass (which is now "Frame Tab" in IE8) which closes the DOC but still leaves the DirectUIHWND visable. closing the DriectUIHWND kills all tabs but leaves the DOC's visable.

Do you know a way of closing a given tab.

Better yet is there a way to have a method return a WebBrowser2 interface or a IHTMLDocument2 or even a HDocVw.InternetExplorer given a IEMainHWND via the Accessibility class.

Thanks,

TAHAIC

P.S. I am a little lost in how the Accessibility class is working - perhaps you could repost the code with some comments.

Answer 2

There is a way to get WebBrowser2 from a handle. You need the handle of Internet Explorer_Server of the tab. (Not IEFrame) If you need the code let me know.

Looking for "entry level" position...

Answer 3

Thanks for responding,

I have been looking at using AccessibleObjectFromWindow function to get WebBrowser2 interface.

Firstly I'm not sure how to marshal it. The standard parameters are:


[DllImport("oleacc.dll")]

private static extern int AccessibleObjectFromWindow(IntPtr hwnd, int dwObjectID, ref Guid riid, IntPtr ppvObject);

but you have:

[DllImport("oleacc.dll")]

private static extern int AccessibleObjectFromWindow(IntPtr hwnd, uint id, ref Guid iid, [In, Out, MarshalAs(UnmanagedType.IUnknown)] ref object ppvObject);

Can you tell me what is going on here?

Reading the documentation I not sure what the objectID needs to be OBJID_WINDOW or OBJID_SELF for example... the refID I think needs to be IID_IDispatch

MSDN quote

"The IWebBrowser2 interface derives from IDispatch indirectly; that is, IWebBrowser2 derives from IWebBrowserApp, which in turn derives from IWebBrowser, which finally derives from IDispatch. "

And then I'm not sure how to use it, or if I need to cast the result etc.

when you say I need the handle of the tab, is that DirectUIHWND or TabWindowClass? The DirectUIHWND seam to be the whole group which I guess has children for each individual tab ...in which case how do I get the tab handle.

 

 

As you can see I am struggling with this so YES, I need the code, if you would be so kind.

Thanks

Answer 4

So far I have come with this for closing a tab.

I noticed that each Tab has a child "Close Tab" - so I added the following:

 public void IEAccessibleCloseTab(IntPtr ieHandle, string tabCaptionToClose)

        {

            AccessibleObjectFromWindow(GetDirectUIHWND(ieHandle), OBJID.OBJID_WINDOW, ref accessible);

            if (accessible == null)

                throw new Exception();

 

            var ieDirectUIHWND = new IEAccessible(ieHandle);

 

            foreach (IEAccessible accessor in ieDirectUIHWND.Children)

            {

                foreach (var child in accessor.Children)

                {

                    foreach (var tab in child.Children)

                    {

                        if (tab.Name == tabCaptionToActivate)

                        {

                            foreach (var  CloseTab in tab.Children)
                               CloseTab.Activate();

                            return;

                        }

                    }

                }

            }

        }

Which works!!

I still need help with getting the WebBrowser2 interface.

Answer 6

Hi Cablehead,

It was verymuch helpfull for me. Is it possible to add new tab and close existing tab?

Answer 7

New Tab:

Just navigate from your IWebbrowser instance with the navOpenInNewTab const.

Tab closing code is posted in this thread by TAHAIC.

Answer 8

Hi Cablehead,

You Rock!
I would like to say thanks for your help.

Answer 9

Hi Cablehead,

I tried this code with my toolbar (bandobject based), but can't get it to work, here is my code

IEAccessibleTabs.

IEAccessible tabs = new IEAccessibleTabs.IEAccessible();

 

List<string> list = tabs.GetTabCaptions((IntPtr) Explorer.HWND);

when I debugged into GetTabCaptions(), looks like "GetDirectUIHWND(ieHandle)" is able to find the DirectUIHWND under IEFrame, but each ieDirectUIHWND.Children doesn't find any child.

My question is the "Tab" in IE8/7 is of class "TabWindowClass" and is the child of "Frame Tab", which is the child of IEFrame, how is it related to the "DirectUIHWND" under tabBandClass?

Thank you!

Hi all,

The GetIEDocumentFromHwnd(IntPtr) didn't works for me....

I'm using another technique for enumerate Windows (Browsers).

public static IDictionary<HWND, string> GetOpenWindows()
        {
            HWND lShellWindow = GetShellWindow();
            Dictionary<HWND, string> lWindows = new Dictionary<HWND, string>();

            EnumWindows(delegate(HWND hWnd, int lParam)
            {
                if (hWnd == lShellWindow) return true;
                if (!IsWindowVisible(hWnd)) return true;

                int lLength = GetWindowTextLength(hWnd);
                if (lLength == 0) return true;

                StringBuilder lBuilder = new StringBuilder(lLength);
                GetWindowText(hWnd, lBuilder, lLength + 1);
                //RealGetWindowClass(hWnd, lBuilder, (uint)lLength + 1);
	       ///Here, i can compare Window Class to get only IEFrames
                lWindows[hWnd] = lBuilder.ToString();

                return true;

            }, 0);

            return lWindows;
        }

        delegate bool EnumWindowsProc(HWND hWnd, int lParam);

        [DllImport("USER32.DLL")]
        static extern bool EnumWindows(EnumWindowsProc enumFunc, int lParam);

        [DllImport("USER32.DLL")]
        static extern int GetWindowText(HWND hWnd, StringBuilder lpString, int nMaxCount);

        static extern bool IsWindowVisible(HWND hWnd);

        [DllImport("USER32.DLL")]
        static extern IntPtr GetShellWindow();

Then, i loop into this Dictionary<IntPtr, string> variable to get IHTMLDocumento from Window Handle.

Do you know if exists any difference between Process.MainWindowHandle and EnumWindows handle?

It returns null always

There is my code...

foreach (KeyValuePair<IntPtr, string> lWindow in OpenWindowGetter.GetOpenWindows())
            {
                IntPtr lHandle = lWindow.Key;
                string lTitle = lWindow.Value;

                IHTMLDocument2 doc = tabs.GetIEDocumentFromHwnd(lHandle);

                if (null != doc)
                    break;
            }

Thanks for your reply.

Answer 11

2 things:

Vista protected mode won't allow Shellwindows...

GetDocumentfromHWND needs the Internet_Explorer_Server hwnd associated with the current tab. (Not the main IEFrame class)

How is "Explorer" object created?

Answer 16

it comes from BandObject project from codeproject.com. The Explorer object is obtained from setSite():

public virtual void SetSite(Object pUnkSite)
  {
            if (BandObjectSite != null)
                //Marshal.ReleaseComObject( BandObjectSite );
                Marshal.FinalReleaseComObject(BandObjectSite);

   if( Explorer != null )
   {
    //Marshal.ReleaseComObject( Explorer );
                Marshal.FinalReleaseComObject(Explorer);
    Explorer = null;
   }

   BandObjectSite = (IInputObjectSite)pUnkSite;
   if( BandObjectSite != null )
   {
    //pUnkSite is a pointer to object that implements IOleWindowSite or something  similar
    //we need to get access to the top level object - explorer itself
    //to allows this explorer objects also implement IServiceProvider interface
    //(don't mix it with System.IServiceProvider!)
    //we get this interface and ask it to find WebBrowserApp
    _IServiceProvider sp = BandObjectSite as _IServiceProvider;
    Guid guid = ExplorerGUIDs.IID_IWebBrowserApp;
    Guid riid = ExplorerGUIDs.IID_IUnknown;
    
    try
    {
     object w;
     sp.QueryService(
      ref guid,
      ref riid,
      out w );
    
     //once we have interface to the COM object we can create RCW from it
     Explorer = (WebBrowserClass)Marshal.CreateWrapperOfType(
      w as IWebBrowser,
      typeof(WebBrowserClass)
      );

     OnExplorerAttached(EventArgs.Empty);
    }
    catch( COMException )
    {
     //we anticipate this exception in case our object instantiated
     //as a Desk Band. There is no web browser service available.
    }
   }

           
  }

using Accessibility;

Where is this assenbly.  How can I get It.
Thx

Answer 18

Don't know if anyone is still checking this thread, but you need to add a reference and select Accessibility, which is at the top I believe

Answer 19

Hi,

I tried out your ie accessible class. but the code from TAHAIC doesn't work. "close tab" child for each tab doesnt exists!

Any other idea to close any tab? Maybe I typed something wrong, but I dont think so. I have the access to all tabs in the foreach loop but no "close Tab" child exists.

Thank you for your response...

You need to activate the tab you want to close first. Only the active tab has a Close Button (use UISpy to see this behaviour)

What I'd like to know is how to go about hooking into all the tabs in an IE window.

Using this code, you can hook the active tabs, but it leaves you with no way to hook into new tabs. The event that triggers (NewWindow2) when you open a link in a new window has an empty ppDisp variable, so no way to know which one you need to use.

For Each ie As SHDocVw.InternetExplorer In New SHDocVw.ShellWindows

 

 

If ie.Name = "Windows Internet Explorer" Then

 

 

Debug.WriteLine(ie.FullName)

 

 

Debug.WriteLine(ie.Application)

 

 

Debug.WriteLine(CType(ie.Document, mshtml.HTMLDocument).referrer)

 

 

AddHandler ie.TitleChange, AddressOf NewIETitle

 

 

AddHandler ie.BeforeNavigate2, AddressOf BeforeNav ' Werkt niet

 

 

AddHandler ie.DocumentComplete, AddressOf DocumentComplete

 

 

AddHandler ie.NewWindow2, AddressOf NewWindow2 ' ppDisp blijft nothing

 

 

AddHandler ie.NewWindow3, AddressOf NewWindow3 ' Hit niet

 

 

Console.WriteLine(ie.HWND & " -> " & ie.LocationURL & " - " & ie.LocationName)

 

 

End If

Hello all,

 

Anyone having success with this method on IE9? The code can't find the "TabBandClass" Class hwnd anymore!

 

Best wishes,
Apex75

Answer 24

Never mind, found it myself! Remove the first two find windows for IE9...

Like this:

            var directUI = FindWindowEx(directUI, IntPtr.Zero, "TabBandClass", null);

            directUI = FindWindowEx(directUI, IntPtr.Zero, "DirectUIHWND", null);

            return directUI;

Answer 25

Never mind, found it myself! Remove the first two find windows for IE9...

Like this:

 

            var directUI = FindWindowEx(directUI, IntPtr.Zero, "TabBandClass", null);

            directUI = FindWindowEx(directUI, IntPtr.Zero, "DirectUIHWND", null);

            return directUI;

 

This won't work at : FindWindowEx(directUI, IntPtr.Zero, "TabBandClass", null); because directUI isn't declared.

Could you please tell me how you did to have it working? It always return a null value with IE 9 .. :/

Thanks!

Answer 26

I am having the same problem with ie9, i made the following adjustment but still not working

      var directUI = FindWindowEx(ieFrame, IntPtr.Zero, "TabBandClass", null);
      directUI = FindWindowEx(directUI, IntPtr.Zero, "DirectUIHWND", null);
      return directUI;

 

Anyone have any suggestions?

thanks

I am too having problem in IE9 as the accessible value is always null. How can I fix it?

Any  help is appreciated.

 

Thanks,

Binaya

Answer 29

Hi,

The problem in IE9 can be fixed using the following.

 

 private IntPtr GetDirectUIHWND(IntPtr ieFrame)
 {
  // For IE 8:
  var directUI = FindWindowEx(ieFrame, IntPtr.Zero, "CommandBarClass", null);
  directUI = FindWindowEx(directUI, IntPtr.Zero, "ReBarWindow32", null);
  directUI = FindWindowEx(directUI, IntPtr.Zero, "TabBandClass", null);
  directUI = FindWindowEx(directUI, IntPtr.Zero, "DirectUIHWND", null);

  if (directUI == IntPtr.Zero)
  {
  // For IE 9:
  directUI = FindWindowEx(ieFrame, IntPtr.Zero, "WorkerW", "Navigation Bar");
  directUI = FindWindowEx(directUI, IntPtr.Zero, "ReBarWindow32", null);
  directUI = FindWindowEx(directUI, IntPtr.Zero, "TabBandClass", null);
  directUI = FindWindowEx(directUI, IntPtr.Zero, "DirectUIHWND", null);
  }

  return directUI;
 }

I got this solution in the following link:

http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/7be1e51d-6b78-41aa-a4a0-e4f20bdaafd5

Hope this helps.

Answer 30

Does anyone has an idea how to automate the "Close other tabs" action?

Activating all tabs (except the initially focused) in turn and closing them one-by-one is unacceptable in my situation.

The best I've achieved so far is:

 

   IntPtr activeTabHwnd = _ieTabWrapper.GetActiveTabButtonHwnd();
   WinFormsUtils.ForceForegroundWindow(activeTabHwnd);
   User32Dll.SetFocus(activeTabHwnd);
   
   // Simulate Ctrl+Alt+F4
   User32Dll.keybd_event((byte)Keys.ControlKey, 0, 0, UIntPtr.Zero);
   User32Dll.keybd_event((byte)Keys.Menu, 0, 0, UIntPtr.Zero);
   User32Dll.keybd_event((byte)Keys.F4, 0, 0, UIntPtr.Zero);

   WaitHelper.Wait(Constants.TabInitializationDelay);

   User32Dll.keybd_event((byte)Keys.F4, 0, (uint)KEYEVENTF.KEYUP, UIntPtr.Zero);
   User32Dll.keybd_event((byte)Keys.Menu, 0, (uint)KEYEVENTF.KEYUP, UIntPtr.Zero);
   User32Dll.keybd_event((byte)Keys.ControlKey, 0, (uint)KEYEVENTF.KEYUP, UIntPtr.Zero);

 

This works most of the time, but fails after some browser automation actions like opening/closing few tabs.

I've tried to set focus to IEFrame, IEServer, TabBandClass windows as well, with similar results.

I've noticed these entries in the resources of ieframe.dll.mui:

 

18161, 	"Close &Other Tabs"
MENUITEM "Close Other &Tabs", 42451, MFT_STRING, MFS_ENABLED

 

I've tried sending these command IDs using WM_COMMAND to above mentioned windows with no luck.

Here's what I'm yet going to try:

1. Pass above command IDs to IOleCommandTarget.Exec method;
2. Access the whole UI tree of Internet Explorer, starting from IEFrame Wnd, through Active Accessibility. Log all accessible objects and found the one for "Close Other Tabs".

If anyone has better ideas, please let me know..

Answer 31

directUI = FindWindowEx(ieFrame, IntPtr.Zero, "WorkerW", "Navigation Bar");

to

directUI = FindWindowEx(ieFrame, IntPtr.Zero, "WorkerW", null);
