Connecting to a running instance of IE

Creating a new IE window is a fairly easy task. But what if you want to use an existing Internet Explorer window, instead of creating a new IE window? Well, in this case, the task is more complicated. The function below finds an Internet Explorer window. sTitleToSearch is the title of the web page to be searched for. Usage of wildcard characters is allowed. If you want to find any IE window, then just enter "*" as the title.

bool CMyInternetExplorer::FindUsingTitle 
              (const CString & sTitleToSearch)
{
    if (m_pWebBrowser != NULL)
    {
        m_pWebBrowser->Release ();
        m_pWebBrowser = NULL;
    }

    HRESULT hr;

    ASSERT (spSHWinds != NULL);

This approach is described in MSDN in more detail. Click here to get more information.

This approach uses SHDocVw.ShellWindows collection to enumerate all the instances of shell windows. The ShellWindows object represents a collection of the open windows that belong to the shell. In fact, this collection contains references to Internet Explorer as well as other windows belonging to the shell, such as the Windows Explorer. To differentiate between Internet Explorer and other shell windows, we just try to get the HTML document of the shell window. If we get the document successfully, then this instance of ShellWindow is in fact an Internet Explorer window.

Navigate to a web page

Now, after we get the web browser object and store it in the variable m_pWebBrowser, it is very easy to navigate to a web page.

void CMyInternetExplorer::Navigate(LPCTSTR lpszURL, DWORD dwFlags /* = 0 */,
    LPCTSTR lpszTargetFrameName /* = NULL */ ,
    LPCTSTR lpszHeaders /* = NULL */, LPVOID lpvPostData /* = NULL */,
    DWORD dwPostDataLen /* = 0 */)
{
    CString strURL (lpszURL);
    BSTR bstrURL = strURL.AllocSysString ();
    
    COleSafeArray vPostData;
    if (lpvPostData != NULL)
    {
        if (dwPostDataLen == 0)
            dwPostDataLen = lstrlen ((LPCTSTR) lpvPostData);
        
        vPostData.CreateOneDim (VT_UI1, dwPostDataLen, lpvPostData);
    }
    
    m_pWebBrowser->Navigate (bstrURL, 
        COleVariant ((long) dwFlags, VT_I4), 
        COleVariant (lpszTargetFrameName, VT_BSTR), 
        vPostData, COleVariant (lpszHeaders, VT_BSTR));
    
    SysFreeString (bstrURL);
}

Wait until the web page is loaded

After starting to load a web page using the function above, to wait until the web page to be completely loaded, we can use the READYSTATE property of IWebBrowser2 object.

bool CMyInternetExplorer::WaitTillLoaded (int nTimeout)
{
    READYSTATE result;
    DWORD nFirstTick = GetTickCount ();

    do
    {
        m_pWebBrowser->get_ReadyState (&result);
        
        if (result != READYSTATE_COMPLETE)
            Sleep (250);
        
        if (nTimeout > 0)
        {
            if ((GetTickCount () - nFirstTick) > nTimeout)
                break;
        }
    } while (result != READYSTATE_COMPLETE);

    if (result == READYSTATE_COMPLETE)
        return true;
    else
        return false;
}

This function waits until the web page is completely loaded or a timeout occurs. To wait indefinitely, set the nTimeout parameter to 0.

Find an anchor on a web page

The following function searches for the specified anchor in a web page. The anchor can be specified either by the name, outer text, tool tip or the URL. The anchor element has the following syntax:

<a href = "anhor_URL" name ="anchor_name" 
title = "anchor_tooltip">Outer Text</a>

If bClick parameter is set to true, then if the anchor is found, it will also be clicked on.

bool CMyInternetExplorer::FindAnchor (bool bClick, bool bFocus,
      bool bName, bool bOuterText, bool bTooltip, bool bURL,
      LPCTSTR sName, LPCTSTR sOuterText, LPCTSTR sTooltip, LPCTSTR sURL)
{
    ASSERT (m_pWebBrowser != NULL);
    if (m_pWebBrowser == NULL)
        return false;
    
    HRESULT hr;
    IDispatch* pHtmlDocDispatch = NULL;
    IHTMLDocument2 * pHtmlDoc = NULL;
    bool bSearch = true;

    // Retrieve the document object.

    hr = m_pWebBrowser->get_Document (&pHtmlDocDispatch);
    if (SUCCEEDED (hr) && (pHtmlDocDispatch != NULL))
    {
        hr = pHtmlDocDispatch->QueryInterface 
            (IID_IHTMLDocument2,  (void**)&pHtmlDoc);
        if (SUCCEEDED (hr) && (pHtmlDoc != NULL))
        {
            IHTMLElementCollection* pColl = NULL;
            hr = pHtmlDoc->get_all (&pColl);

            if (SUCCEEDED (hr) && (pColl != NULL))
            {
                // Obtained the Anchor Collection...

                long nLength = 0;
                pColl->get_length (&nLength);
                
                for (int i = 0; i < nLength && bSearch; i++)
                {
                    COleVariant vIdx ((long)i, VT_I4);

                                    }
                                    pAnchor->Release ();
                                }
                            }
                            pElem->Release ();
                        }
                        pElemDispatch->Release ();
                    }        
                }
                pColl->Release ();
            }
            pHtmlDoc->Release();
        }
        pHtmlDocDispatch->Release ();
    }
    
    if (bSearch == false)
        return true;

    return false;
}

The idea here is very simple. We first enumerate all IHTMLElement objects using get_all function of IHTMLDocument2. Then we check all of the elements to see whether it is an anchor object (IHTMLAnchorElement) or not, by checking its tag name. If it is an "a" or an "A", then it is an anchor object. Then I try to get the IHTMLAnchor object by using the QueryInterface function. The reason that I check the name instead of just using QueryInterface function is performance related. I guess it is much faster to check a tag's name than trying to get IHTMLAnchorElement by using QueryInterface function.

Fill a form on a web page

The idea here is similar to the one above. Instead of finding the anchor element, I try to find all the input elements and then do the same operations. The syntax for an input element is a follows:

<input type="input_type" value="input_value" name="input_name">

Some points that you should keep in mind

The attached source code includes a few more functions to fill the forms on web pages.
The source code above does not search inside Frame objects. However, this should not be a hard task. The frame objects should be enumerated and then the IHTMLDocument2 of each frame should be checked recursively. May be I will implement this in the next update.
In order to use IHTMLInputElement object, you need at least Internet Explorer 5.0
I am not an expert Internet Explorer programmer. Lately, I needed to automate Internet Explorer and then wrote these functions. I wrote most of them on my own, and they may have some bug fixes in it.
Please do not ask me why I used MFC, not ATL. The reason is that I don't know ATL :( However, if you guys help me to convert this code into ATL, I would be very glad. I may even start learning ATL :-)

Crashes in CMyInternetExplorer::FindUsingTitle

robzzzzz

22:49 15 Apr '08

Hi!

I tried the code in CMyInternetExplorer::FindUsingTitle() but it kept crashing. WTF

I fixed it by adding m_spSHWinds.Release();


	HRESULT h = CoInitializeEx( NULL, COINIT_MULTITHREADED );
	if( S_OK != h )
	{
		AfxMessageBox( L"Ewwww!" );
		return;
	}

	SHDocVw::IShellWindowsPtr m_spSHWinds;

	h = m_spSHWinds.CreateInstance( __uuidof( SHDocVw::ShellWindows ) );
	if( S_OK != h )
	{
		AfxMessageBox( L"Ewwww!" );
		return;
	}

	CString strCount;
	long nCount = m_spSHWinds->GetCount();

	strCount.Format(L"%i", nCount);
	OutputDebugString( strCount );

	m_spSHWinds.Release();

	CoUninitialize();

Re: Strange Behavior in ie7

That is due to the "Protected Mode" in IE7. What happens is, when you call the IE7 and tell it to create a new instance, it creates a new instance with protected mode set to off (if you application is not a low privileged application). And then when you try to navigate to yahoo.com, IE7 decides that yahoo.com is not in the trusted zones, so it opens a new IE7 window with protected mode set to ON this time and navigates to it.

Well, the thing that sucks is that IE7 does not tell us about this new instance it created and when you try to do things on the original instance, it obviously fails.

The easiest solution for this is to turn of the protected mode completely. If that is not an option, I don't really know a way to run IE7 in protected mode and get a handle to its COM interface. There is a new API that can launch IE7 in protected mode, may be using that API and then attaching to that instance might work. I never tried that though.

You need to install Platform SDK and you need to install the IE SDK within the platform SDK. Also, you need to add the include directories and library directories to the appropriate places in DEV C++.

Hello Mustafa,

I saw your that you have experience in creating AddOns for IE.

We are building a similar AddOn for IE which would display meaning in different languages. Our AddOn is working fine in IE6 and funtionality is also working fine in IE7 but IE7 crashes everytime we click on dropdown.

You can see the exact problem here:

I would appreciated if you can help us.

Thank you in advance

Nice article

Hi,

This was a nice article.
I am following what you have suggested for one of my projects. However, I am handling a particular case where I need to post the data to a particualr url [ without actually naivgating to the url ] so as to remain in my current page after the POST operation without reloading my page again.

Is this possible ?
Would you like to share your thoughts if you know how to do this ?

Thanks,
Andy

I dont really know how to do that. But you might try doing something like this: Create a IHTMLScriptElement and put your post event in there. Then create a hidden button and call this script from that button. And lastly click on the hidden button you created. After that, you can wait for the page to load.

I have no idea if this will work or not though Wink

Hi, Mustafa! Thank you for your article! It’s a great start for understanding "web browser object" for me. Can you also recommend some books on this subject (IWebBrowser2, IHTMLDocument2 and IHTMLElement objects), please? I’ve searched through amazon but had no luck finding them. Thank you in advance.

I am glad that it was of some help. Honestly, I dont know any good references or books for this subject. The only information that I found in this topic was MSDN Library and some discussion forums on the Internet.

IHTMLInputFileElement

using IHTMLInputFileElement object, put_value does not work. Any hints here? It returns OK, but nothing happends. MSDN sais that using value of an file type input in scripting is read-only. But nothing for IHTMLInputFileElement interface. Dragos.

getting the source of an image from IE

cata_1000

10:24 3 May '05

Hi,
Great code!
Because this article is about connecting to a IE instance I thought that I can get an answer to solve a problem that trubles me for some days.
I have to get an image (binary) from IE, but the source code is something like:
<img src="blabla.asp?img=1" border=0 align=absmiddle>
I've made a list with Image elements (IHTMLImgElement) but when I try to get the file size of the image I get -1 or when I try to get the name I get ""...
For the rest of the images the functions worked fine.
From IE I can right click on the image and save it to the disk, so I think there must be a way to get the image binary somehow.
If there is anybody that could help I will appreciate.
Thank you.

microsoft sdk Errors

Krazyman

10:42 1 Mar '05

i was wondering if anyone can help with this, after i installed the core and internet SDK i get 23 errors . i wount list them all but they are to this effect

c:\program files\microsoft sdk\include\shtypes.h(102) : error C2011: '_SHITEMID' : 'struct' type redefinition
c:\program files\microsoft sdk\include\shlwapi.h(61) : error C2143: syntax error : missing ';' before '{'
c:\program files\microsoft sdk\include\shlwapi.h(61) : error C2447: missing function header (old-style formal list?)

[half of them are this error]
c:\program files\microsoft sdk\include\mshtml.h(40522) : error C2061: syntax error : identifier 'LONG_PTR'

i have been trying to figure out what to do for a couple days now . if anyone has an answer i would appreciate it.
----------------------------
update: i managed to get rid of some of the errors however this is most likly not the best (or even right) way to do it
for half of them i just deleted #include . for all the errors with LONG_PTR i just went into mshtml.h and changed the LONG_PTR to LONG. if anyone has a better way to do it please let me know
