正在等待在计时器中加载WebBrowser

browser winforms c#

samy · 技术社区 · 12 年前

我正在创建一个简单的自动冲浪应用程序来学习WebBrowser对象。

我每隔几秒钟就会浏览一次23个URL的列表。

该应用程序很简单,进入论坛并打开FORM添加新消息(无需发送) 一直走到最后。

我的问题是代码 forumAction.FillOutFormIn(webBrowser1.Document); 在错误的站点执行。

我认为这是因为文件还没有准备好。

那么,有没有办法在文档准备好之前停止计时器执行代码?

这是 TIMER TICK 功能:

//I start is in 21 for faster testing.
int timesToRun = 21;
    private void Time_Tick(object sender, EventArgs e)
    {

            Console.WriteLine(timesToRun.ToString());
            string currentSite = siteList.GetSiteFromIndex(timesToRun);

            webBrowser1.Document.Window.Navigate(currentSite);

            //I think I need to wait here until the document is ready

            //this line of code doesn't run on timeToRun = 22
            forumAction.FillOutFormIn(webBrowser1.Document);

            Console.WriteLine(webBrowser1.Url);
            timerLabel1.Text = siteList.SiteLists.Count + ">" + timesToRun + "";

            if (timesToRun >= siteList.SiteLists.Count - 1)
            {
                enableControls(true);
                timesToRun = 0;
                timer.Stop();
                Console.WriteLine("done");

            }

            timesToRun++;          
    }

(对不起我的英语)

您可以简单地对 DocumentCompleted 控制事件。

这将允许您在加载页面时重新启动计时器。

webBrowser1.Navigated += WebBrowser_DocumentCompleted;
timesToRun = 22;

private void Time_Tick(object sender, EventArgs e)
{
    timer.stop();
    webBrowser1.Document.Window.Navigate(url);
}

void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    timesToRun--;
    if(timesToRun > 0)
    {
        timer.Start();
    }
}

添加这样的事件

You could disable your timer in your Time_tick function, 

timer1.Enabled = false;

然后在doc completed事件中重新启用:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    if(timesToRun > 0) 
    { 
        timer1.Enabled = true;
    }
}

//我开始是在21更快的测试。 int timesToRun=21; private void Time_Tick(对象发送方,EventArgs e) {

        Console.WriteLine(timesToRun.ToString());
        string currentSite = siteList.GetSiteFromIndex(timesToRun);

        webBrowser1.Document.Window.Navigate(currentSite);

        //I think I need to wait here until the document is ready

        //this line of code doesn't run on timeToRun = 22
        forumAction.FillOutFormIn(webBrowser1.Document);

        Console.WriteLine(webBrowser1.Url);
        timerLabel1.Text = siteList.SiteLists.Count + ">" + timesToRun + "";

        if (timesToRun >= siteList.SiteLists.Count - 1)
        {
            enableControls(true);
            timesToRun = 0;
            timer.Stop();
            Console.WriteLine("done");

        }

        timesToRun++;          
}
