在线急等！小妹我又遇到麻烦事情了！！高手快快来帮忙吧！看看这段程序啊！拜托了／

private void browser_DocumentComplete(object sender, AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent e)
{
mshtml.IHTMLDocument3 doc = this.browser.Document as mshtml.IHTMLDocument3;

mshtml.IHTMLElementCollection collection = doc.getElementsByTagName("div");

foreach(mshtml.IHTMLElement element in collection)
{
if(element.className == "editable")
{
((mshtml.HTMLElementEvents2_Event)element).onclick +=
new mshtml.HTMLElementEvents2_onclickEventHandler(this.element_onClick);
}
}

}

private bool element_onClick(mshtml.IHTMLEventObj e)
{
System.Windows.Forms.OpenFileDialog of = new OpenFileDialog();

if(System.Windows.Forms.DialogResult.OK == of.ShowDialog())
{
return true;
}

return false;
}

我的目的是在单击文本筐的时候．弹出一个对话筐．这个代码可以实现．但是
只可以实现一次．也后我点击就没反应了．（用的是mshtml和web Browser）.
快救我！
