接受在web浏览器

Question

本地对话框我有以下代码

void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) 
{ 
    if (current_state == "request_4") 
    { 
     webBrowser1.Invoke(new Action(() => webBrowser1.ScriptErrorsSuppressed = true)); 
     webBrowser1.Invoke(new Action(() => webBrowser1.Refresh(WebBrowserRefreshOption.Completely))); 
     InjectAlertBlocker(); 
    } 
} 
private void InjectAlertBlocker() 
{ 
    HtmlElement head = webBrowser1.Document.GetElementsByTagName("head")[0]; 
    HtmlElement scriptEl = webBrowser1.Document.CreateElement("script"); 
    IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement; 
    string alertBlocker = "window.alert = function() { }"; 
    element.text = alertBlocker; 
    head.AppendChild(scriptEl); 
} 

我做的请求的刷新是POST请求的web浏览器等等实例问我所有的时间，如果我要“重试”的通过显示对话框窗口来请求或不要求。我怎么能接受它或根本不显示？

抑制错误或InjectAlertBlocker()没有帮助。

我没有真正了解http://www.codeproject.com/Articles/31163/Suppressing-Hosted-WebBrowser-Control-Dialogs这种方法。

我很感激，如果有人可以解释如何使用该解决方案。

该代码做的伎俩，但我仍然不喜欢它，因为它需要从我正在使用的当前窗口焦点。
