Using "GetObject" and "winmgmts" to ping devices.

I found the following bit of code online yesterday. This is awesome in it's speed. I have been using an entirely different method to ping devices from within Excel. This code is much faster.

However, I do have a question about it. I don't understand its syntax. How would I add the parameter to shorten the time out? Currently, it is about 2 seconds. In my case, I'd be happy shortening that to 1/2 second ( 500ms ).

Function GetPingResult$(Host$)
Dim objPing As Object
Dim objStatus As Object
'Dim Result$
   Set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}"). _
       ExecQuery("Select * from Win32_PingStatus Where Address = '" & Host & "'")
'
   For Each objStatus In objPing
      Select Case objStatus.StatusCode
         Case 0: GetPingResult = "Up"
         Case 11001: GetPingResult = "Buffer too small"
         Case 11002: GetPingResult = "Destination net unreachable"
         Case 11003: GetPingResult = "Destination host unreachable"
         Case 11004: GetPingResult = "Destination protocol unreachable"
         Case 11005: GetPingResult = "Destination port unreachable"
         Case 11006: GetPingResult = "No resources"
         Case 11007: GetPingResult = "Bad option"
         Case 11008: GetPingResult = "Hardware error"
         Case 11009: GetPingResult = "Packet too big"
         Case 11010: GetPingResult = "Request timed out"
         Case 11011: GetPingResult = "Bad request"
         Case 11012: GetPingResult = "Bad route"
         Case 11013: GetPingResult = "Time-To-Live (TTL) expired transit"
         Case 11014: GetPingResult = "Time-To-Live (TTL) expired reassembly"
         Case 11015: GetPingResult = "Parameter problem"
         Case 11016: GetPingResult = "Source quench"
         Case 11017: GetPingResult = "Option too big"
         Case 11018: GetPingResult = "Bad destination"
         Case 11032: GetPingResult = "Negotiating IPSEC"
         Case 11050: GetPingResult = "General failure"
         Case Else: GetPingResult = "Unknown host"
      End Select
'      GetPingResult = strResult
   Next
   Set objPing = Nothing
End Function

Ok... So you made me look...

And, this I found:

   Set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}"). _
       ExecQuery("Select * from Win32_PingStatus Where Timeout = " & timeout & " AND Address = '" & Host & "'")

I'm tweaking the timout value to speed things up. I'd lowered it to 350.
