Web Browser Event Hook - Problems

[Jacobb Michael]

Hi all, I have some issues on Registering event, If you have any idea on my implementation please help me …

private SHDocVw.InternetExplorer browser;
HTMLDocument document;
HTMLDocumentEvents2_Event DocEvents;

This Event Fires well, when ever I click on any link the event is fired no issue on that. But when I click on the Text box the focus losts.

browser = (SHDocVw.InternetExplorer)pDisp;
DocEvents = (mshtml.HTMLDocumentEvents2_Event)document;
DocEvents.onclick += new HTMLDocumentEvents2_onclickEventHandler(DocEvents_onclick);

To over come this issues I have just implemented from one of the articles like bellow

// The delegate:
public delegate void DHTMLEvent(IHTMLEventObj e);

///
/// Generic Event handler for HTML DOM objects.
/// Handles a basic event object which receives an IHTMLEventObj which
/// applies to all document events raised.
///
\[ComVisible(false)\]
public class DHTMLEventHandler
{
    public DHTMLEvent Handler;
    mshtml.HTMLDocument Document;
    public DHTMLEventHandler(mshtml. HTMLDocument doc)
    {
        this.Document = doc;
    }
    \[DispId(0)\]
    public void Call()
    {
        Handler(Document.parentWindow.@event);
    }
}

browser = (SHDocVw.InternetExplorer)pDisp;
mshtml.HTMLDocument doc = (mshtml.HTMLDocument)browser.Document;
DHTMLEventHandler Handler = new DHTMLEventHandler(doc);
Handler.Handler += new DHTMLEvent(this.myCallback);
doc.onclick = Handler;

but it shows the bello error. Ambiguity between 'mshtml.DispHTMLDocument.onclick' and 'mshtml.HTMLDocumentEvents_Event.onclick So I have changed from mshtml.HTMLDocument to mshtml.DispHTMLDocument Now there is no compilation error but while excecuting it shows the bellow error System.NotImplementedException , NotImplemented “\r\n” Somewhat I got the information that we have to use mshtml. IHTMLDocument2 So I have used as bellow

public delegate void DHTMLEvent(mshtml.IHTMLEventObj e);

    \[ComVisible(true)\]
    public class DHTMLEventHandler
    {
        public DHTMLEvent Handler;
        mshtml.IHTMLDocument2 Document;

        public DHTMLEventHandler(mshtml.IHTMLDocument2 doc)
        {
            this.Document = doc;
        }

        \[DispId(0)\]
        public void Call()
