VB6应用程序：WebBrowser.Navigate刷新每3分钟 [英] VB6 application : WebBrowser.Navigate refresh every 3 minutes

问题描述

我正在使用VB6中使用此code推出了web浏览器窗口中的应用程序：

I am making an application using VB6 in which a WebBrowser window is launched using this code:

     Private Sub Form_Load()
     WebBrowser1.Navigate ("http://google.com")
     End Sub

我怎样才能使窗口刷新相同的URL每一个让我们例如3分钟呢？
我知道它应该是众所周知的事情，但我仍然可以通过VB编程

How can I make the window refresh the same url every let's say 3 minutes ? I know it should be something well known but i am still searching my way through VB programming

推荐答案

您不需要2计时器。只是有一个全局变量 globalTimer随着日期，让你驾驶的最后一次
您可以设置定时器运行每一秒或分钟。为了更准确，我建议每一秒。

You don't need 2 timers. just have a global variable globalTimer As Date that keeps the last time you navigated You can set Timer1 to run every second or minute. To be more accurate, I recommend every second.

Dim globalTimer As Date
...
Private Sub Timer1_Timer()
    If Now >= DateAdd("n", 3, globalTimer) Then    ' its been at least 3 minutes since last Navigation
        WebBrowser1.Navigate ("http://google.com") ' Navigate
        globalTimer = Now                          ' store the new navigation time
    End If
End Sub
