Implementing the "View Source" option in Internet Explorer


This is the code for implementing the "View Source" option in Internet Explorer

void CMyBrowser::OnViewSource() 
	CWnd* pWnd = NULL; 

	CWnd* pwndShell = m_WebBrowser2.GetWindow(GW_CHILD); // get the webbrowser window pointer

	if (pwndShell) 
		pWnd = pwndShell->GetWindow(GW_CHILD);  //get the child window pointer
	if(pWnd != NULL) 
		WPARAM wParam = MAKELONG(IDM_VIEWSOURCE, 1);  //convert to unsigned 32 bit value and pass it to WPARAM
		pWnd->SendMessage(WM_COMMAND, wParam, (LPARAM)pWndHTML->m_hWnd); //cool send a message to retreive the source.

    i have a question about WebBrowser control

    are you know how to read the control WebBrowser Page content after you make
    a navigation to a specified URL .

    The problem:

    i want to navigate to yahoo finance and make a quote of a stock value .

    // after navigate to URL with the WebBrowser control and ask for microsoft (MSFT ) stock value ,
    for example:

    pWebBrowser ->Navigate( "";)

    // now i want to read the stock LAST TRAD value .

    // to do this i need to read the HTML content of the WebBrowser control ,
    // it's the same if you do "View Source" in Internet Explorer , then you can see the LAST TRAD value in the
    // content of the HTML page .

    so if you have any idea how to read the content of an HTML page after navigate to this page , ? please help me !

    thanks is advance !

    Ron bar yosef .

  • Where'd you get the reference to IDM_VIEWSOURCE

    Could this technique be used to invoke any context menu item?

  • Another way...

    InternetReadFile(hService, lpBuffer, dwBytesAvailable, &dwBytesRead);
    CString name = lpBuffer;
    heMail = CreateFile ("C:\\windows\\temp\\tmp.txt",GENERIC_WRITE,

    WriteFile (heMail,name,strlen(name),&dwWritten, NULL);


    // AfxMessageBox(lpBuffer);

    Can you specify what is GW_CHILD and where you define it.
