Hello!

I developed the Chatting Application using MFC class.
Within this project, some web pages are displaed and interact with CHtmlView class.
And I sucessfullly, called the javascript function of the web page from MFC class.
I'll show you the code that MFC class call the javascript function.

	IHTMLDocument2* pCtrl=(IHTMLDocument2*)m_oMainDlg.m_pWebCtrl->GetHtmlDocument();
	IHTMLWindow2 *pWindow=(IHTMLWindow2*)NULL;
	pCtrl->get_parentWindow(&pWindow);

	BSTR strLanguage;
	BSTR strSript;
	strLanguage=L"JScript";
	CString strTmp;
	strTmp.Format("LoadMovie(\"%s\");", strURL);
	_bstr_t strBuffer(strTmp);
	strSript=(BSTR)strBuffer;
	VARIANT nResult;
	HRESULT hResult;
	hResult=pWindow->execScript(strSript, strLanguage, &nResult);

But I can know the method, that MFC can catch the event or meesage of the web page.
For example, How MFC class can catch the  mouse evet of the image
object of the web page?
This is very important to me.
Thanks.

This demo project has what you're looking for...

"This example demonstrates how to access DHTML object model and how to
intercept the DHTML element events. It also demonstrates how to use
connectionpoint with MFC. The demo program first loads up a sample
HTML page which contains two button elements and a listbox element.
Then it accesses button element DHTML object and intercepts its Click,
DoubleClick, MouseMove, MouseOver, MouseDown and MouseUp events. After
the program intercepts an event, it records the event information to
the listbox element on the sample HTML page. The example shows that
MSHTML is very useful for Internet and web programming. I hope this
example would provide some help for any one who wants to use MSHTML
library. (You need to download ie5_lib or later IE library to compile
the demo project.)"
