vbs ping实现的两种方式
<p>对于vbs中ping的实现可以通过两种方式 ：</p><ul>
<li>1、调用系统ping命令；</li>
<li>2、使用wmi查询pingstate类处理。<br />
</li>
</ul>
<p>1、调用系统ping命令</p>
<div class="jb51code">
<pre class="brush:vb;">
Set wshell = CreateObject("WScript.Shell")
wshell.run("ping 182.183.101.1",0.true)
</pre>
</div>
<p>对于以上调用，如果想对其进行过滤，可以考虑将运行结果重定向到文件，在读到一个string中，查找其中是否有timeout或超时字符，判断是否超时。本打算直接拼接命令重定向到文件，但怎么都不成功，所以run调用一个bat，bat中写：ping 192.168.101.1 -n 1 -w 1200 </p>
<p>2、使用wmi查询pingstate类处理：</p>
<div class="jb51code">
<pre class="brush:vb;">
'url = "www.baidu.com"
url = "119.75.217.109"
strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colPings = objWMIService.ExecQuery ("Select * From Win32_PingStatus where Address = '" & url & "'")
For Each objPing in colPings
MsgBox url & " responded to ping." & vbcrlf &_
"Responding Address: " & objPing.ProtocolAddress & vbcrlf &_
"Responding Name: " & objPing.ProtocolAddressResolved & vbcrlf &_
"Bytes Sent: " & objPing.BufferSize & vbcrlf &_
"Time: " & objPing.ResponseTime & " ms"
Next
</pre>
</div>
