懂mshtml事件的同志看过来

俺用VJ生成了HTMLInputTextElementEvents2的wrapper类，
然后用InputTextHandler2实现了HTMLInputTextElementEvents2，
然后得到IHTMLInputTextElement,
然后FindConnectionPoint,
然后Advise，
然后收不到任何消息。

Why?
源码如下：

class InputTextHandler2 implements HTMLInputTextElementEvents2
{
public boolean onhelp(mshtml.IHTMLEventObj pEvtObj){return false;}
public boolean onclick(mshtml.IHTMLEventObj pEvtObj){return false;}

public void onreadystatechange(mshtml.IHTMLEventObj pEvtObj){}
public boolean onchange(mshtml.IHTMLEventObj pEvtObj){

return false;
}

}

java.util.Vector cookie;
InputTextHandler2 h;

private void menuItem4_click(Object source, Event e)
{
cookie=new java.util.Vector();
IHTMLDocument2 doc = (IHTMLDocument2)((shdocvw.IWebBrowser2)(webBrowser.getOcx())).getDocument();
IHTMLElementCollection cols = (IHTMLElementCollection)(doc.getAll().tags(new Variant("INPUT")));

h = new InputTextHandler2();

for (int i=0; i<cols.getLength(); i++)
{
IHTMLInputTextElement ele;
Object o = cols.item( new com.ms.com.Variant(i),new com.ms.com.Variant(i) );
if (o instanceof IHTMLInputTextElement)
{
ele = (IHTMLInputTextElement)o;
IConnectionPointContainer connectionContainer = (IConnectionPointContainer)ele ;
IConnectionPoint cp = connectionContainer.FindConnectionPoint(HTMLInputTextElementEvents2.iid) ;
if (cp!=null)
{
int coo = cp.Advise(h);
cookie.addElement( new Integer(coo)) ;
//com.ms.com.ComLib.release(cp) ;
}
}
}
}

补充一下，已经找到了IHTMLInputTextElement，Advise也似乎成功。

随便给点提示吧，谁用过HTMLInputTextElementEvents2？
