ping in vbscript

Hi,

I wrote a script to get the output of ping every few minutes.
This is part of my script:

Set objShell = CreateObject("WScript.Shell")
Set objExec = objShell.Exec("ping -n 4 -w 1000 " & serverName)
strPingResults = LCase(objExec.StdOut.ReadAll)

Since ping runs in a window, a window pops up every few minutes when my script is running and I don't want that. I would like to get the output from pinging a server without a window showing up every few minutes. How can I do that? Should I be calling some other ping program?

Thank you

Check out http://support.microsoft.com/default.aspx?scid=kb;en-us;300197 ("HOW TO: Ping an IP Address with Visual Basic by Using ICMP"), maybe you can change that to work with VBS.

Hello,
I don't know of a way to hide the window using objShell.Exec

If the link above doesn't work out for you then let me know what you would like to with the
"strPingResults" and I will post a script for you

From strPingResults, I need to get the average response time. For example, if this is the output of ping, I need to get the number 40.

Pinging www.google.akadns.net [216.239.57.104] with 32 bytes of data:

Here is a sample that will get the response time of a ping
but we have to use a loop to ping 4 times to find the average:

'!!!Begin Copy
Dim strHost, strTarget, colPingResults, objPingResult, strPingRT,i

strHost = "."
strTarget = "www.google.akadns.net"

Do Until i = 4
Set colPingResults = GetObject("winmgmts:{impersonationLevel=impersonate}//" & _
        strHost & "/root/cimv2").ExecQuery("SELECT * FROM Win32_PingStatus " & _
        "WHERE Address = '" + strTarget + "'")

For Each objPingResult In colPingResults
    If objPingResult.StatusCode = 0 Then
       Ping = True
        strPingRT = strPingRT + objPingResult.responsetime
       
      Else
        Ping = False
    End If
     
Next
i = i + 1
Loop
wscript.echo strPingRT / 4

'!!End Copy

the line (line 12)....If objPingResult.StatusCode = 0 Then...
is there incase your script needs to know if there was a response or not.

But does Win32_PingStatus work on Windows 2000? I am getting an error when I run this script...

Well you are right it doesn't work in W2K...sorry

The best I can come up with is to use cscript.exe to call your existing vbs file.
I have tried this on my W2k machine and it worked

Place these 2 lines in a seperate vbscript and replace c:\ExistingFile.vbs with your existing file
If there is a space in the folder path you will need to use the 8.3 format...e.g Documents and Settings = docume~1

Set wshshell = CreateObject("WScript.Shell")
wshshell.run "cmd /c cscript //nologo c:\ExistingFile.vbs",0

Good Luck!
