Ping script with loop and save in a txt - vbscript

Question

i try to make an Ping script with vbs. I need a Script, that ping (no ping limit, the program will run all the time) a computername in the network every 2 seconds and save the results in a txt file.
For Example:
06/08/2010 - 13:53:22 | The Computer "..." is online
06/08/2010 - 13:53:24 | The Computer "..." is offline
Now i try a little bit:
strComputer = "TestPC"
Set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}")._
ExecQuery("select * from Win32_PingStatus where address = '"_
& strComputer & "'")
For Each objStatus in objPing
If IsNull(objStatus.StatusCode) Or objStatus.StatusCode <> 0 Then
..........
Next
And than i don't know how to make it. (I'm new with vbs :-))
I hope some one can help me.
Greeting,
matthias

Try this
Option Explicit
Dim strHost, strFile
strHost = "www.google.com" '"127.0.0.1"
strFile = "C:\Test.txt"
PingForever strHost, strFile
Sub PingForever(strHost, outputfile)
Dim Output, Shell, strCommand, ReturnCode
Set Output = CreateObject("Scripting.FileSystemObject").OpenTextFile(outputfile, 8, True)
Set Shell = CreateObject("wscript.shell")
strCommand = "ping -n 1 -w 300 " & strHost
While(True)
ReturnCode = Shell.Run(strCommand, 0, True)
If ReturnCode = 0 Then
Output.WriteLine Date() & " - " & Time & " | The Computer " & strHost & " is online"
Else
Output.WriteLine Date() & " - " & Time & " | The Computer " & strHost & " is offline"
End If
Wscript.Sleep 2000
Wend
End Sub

You put your pings inside a loop of some kind and then use Wscript.Sleep 2000 to sleep for 2 seconds.
Then you use the File System Object (FSO) to write to a file. Information can be found here.
Edit: Something like this might work:
Const OpenFileForAppending = 8
Dim fso, ts
Set fso = CreateObject("Scripting. FileSystemObject")
While 1 > 0 ' loop forever
Set ts = fso.OpenTextFile("c:\temp\test.txt", OpenFileForAppending, True)
' do your pinging code
'if ok
ts.WriteLine("OK")
'else
ts.WriteLine("Not OK")
'endif
ts.Close()
Wscript.Sleep 2000
Wend
