使用 VBScript 检查网络连接 [英] Check network connection with VBScript

问题描述

我正在多台计算机设备上运行基于网络的幻灯片.我有一个在启动时运行的 VBScript，打开 IE 并以全屏模式导航到特定页面.只要在启动时有互联网连接，一切都很好.如果没有，则页面永远不会加载.在 VBScript 中有没有办法每隔几分钟检查一次连接，直到找到连接，然后继续执行脚本?这是供您参考的代码:

I'm running a web-based slideshow on multiple computer units. I have a VBScript that runs on startup, opens IE and navigates to a specific page in fullscreen mode. Everything works great, as long as there's an internet connection on startup. If there isn't then the page never loads. Is there a way in VBScript to check for a connection every couple minutes until the connection is found, and then continue with the script? Here is the code for your reference:

Option Explicit     
Dim WshShell
set WshShell = WScript.CreateObject("WScript.Shell")         

On Error Resume Next
   With WScript.CreateObject ("InternetExplorer.Application")     
      .Navigate "http://www.example.com/slideshow"
      .fullscreen = 1   
      .Visible    = 1
      WScript.Sleep 10000
   End With    
On Error Goto 0

推荐答案

参考这个 ==> 循环函数?

是的，您可以使用此代码轻松完成:

Yes, you can do it easily with this code :

Option Explicit
Dim MyLoop,strComputer,objPing,objStatus
MyLoop = True
While MyLoop = True
    strComputer = "smtp.gmail.com"
    Set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}!\\").ExecQuery _
    ("select * from Win32_PingStatus where address = '" & strComputer & "'")
    For Each objStatus in objPing
        If objStatus.Statuscode = 0 Then
            MyLoop = False
            Call MyProgram()
            wscript.quit
        End If
    Next
    Pause(10) 'To sleep for 10 secondes
Wend
'**********************************************************************************************
 Sub Pause(NSeconds)
    Wscript.Sleep(NSeconds*1000)
 End Sub
'**********************************************************************************************
Sub MyProgram()
Dim WshShell
set WshShell = WScript.CreateObject("WScript.Shell")         
On Error Resume Next
   With WScript.CreateObject ("InternetExplorer.Application")     
      .Navigate "http://www.example.com/slideshow"
      .fullscreen = 1   
      .Visible    = 1
      WScript.Sleep 10000
   End With    
On Error Goto 0
End Sub
