VB 2005 .aspx页面的定时器组件？ [英] Timer Component for VB 2005 .aspx page?

问题描述

我正在使用

My.Computer.Network.Ping创建一个监控服务器状态的网站。我正在寻找一种方法来每隔一秒左右触发我的Ping（）

功能。我看到一个Timer控件可用于Windows

表单，但它没有列在我的.ASPX页面中。是否有这样的控制？


谢谢。

I''m creating a website that monitors the status of servers using
My.Computer.Network.Ping. I''m looking for a way to fire off my Ping()
function every second or so. I see a Timer control availalble for Windows
forms but it is not listed for my .ASPX page. Is there such a control?

Thanks.

推荐答案

Ryan，

在Atlas中应该有这样的控制，标准你可以这样做。

Ryan,

There should be such a control in Atlas, standard you can make it like this.

I hope this helps,

你好瑞恩，

至于计时器组件，我假设您将在ASP.NET应用程序中执行一些

常量操作。这个操作是否特定于个人webform页面或者是一个应用程序范围

操作（就像背景工作者......）？ Cor提供的文章

演示了如何创建javascript客户端计时器，这将在网页的client-sdie html中不断调用脚本函数。 />
文件。但是，如果您想要的是服务器端背景计时器，我认为您需要创建服务器端后台工作线程或

System.Timers。定时器实例做的工作.eg


==================

void Application_Start（对象发件人，EventArgs e）

{

计时器计时器=新的System.Timers.Timer（）;


HttpContext.Current。应用程序[" g_timer"] =计时器;


timer.Elapsed + = new ElapsedEventHandler（this.OnTimedEvent）;

timer.Interval = 4000;

timer.Enabled = true;

}

==================== =======

Hello Ryan,

As for the timer component, I assume that you''re going to perform some
constant operations in your ASP.NET application. Is this operation
specific to individual webform page or is a application wide
operations(like a backgroun worker...)? The article Cor has provided
demonstrates how to create javascript client-side timer which will
constantly call a script function in the web page''s client-sdie html
document. However, if what you want is a server-side backgroun timer, I
think you would need to create a server-side background worker thread or a
System.Timers.Timer instance to do the work .e.g.

==================
void Application_Start(object sender, EventArgs e)
{
Timer timer = new System.Timers.Timer();

HttpContext.Current.Application["g_timer"] = timer;

timer.Elapsed += new ElapsedEventHandler(this.OnTimedEvent);
timer.Interval = 4000;
timer.Enabled = true;
}

谢谢史蒂文，这是有效的。但是，我的页面上有图像显示正在ping通的服务器的状态和这些图像没有被改变

苍蝇。我的Ping函数根据Ping成功或失败是否为
来更改ImageURL属性（成功为绿色图像，失败为红色）。我是否需要重新加载整个页面才能更新单个图像，或者是否需要另外一种方法来获取该图像以在页面上动态更新？

谢谢。

Thanks Steven, this works. However, I have images on my page showing the
status of the servers being pinged and these images are not being changed on
the fly. My Ping function changes the ImageURL property based on whether
the Ping succeeds or fails (green image for success, red for failure). Do I
have to re-load the entire page just to update a single image or is there
another way to get just that image to update dynamically on the page?

Thanks.
