Fast Pinging from VB

I wanna know if is there any way to ping other computers on LAN and it must be very fast in getting response.

Because i will ping about 30 computers and get their responses. I will try to determine which computer is online and which is offline by pinging them.

Also if you have any other idea to do that without pinging and without using program on clients i will be glad to hear from you.

Thanks.

I am not sure how you can ping a computer over a LAN in vb but search www.vbcode.com they might an example. I know they have code to ping a website maybe that uses the same kind of thing.

You can but it aint gonna be any faster just coz it's from vb!
It still will be as fast as from a command prompt etc.

A better way would be to have a client app to run on a client pc and test if connected to network or if connected to internet!

Attached is a module to use:

On a form put:

VB Code:

Dim ECHO As ICMP_ECHO_REPLY  
 
  'ping an ip address, passing the
  'address and the ECHO structure
   Call Ping("127.0.0.1", ECHO)
   
   
  'display the results from the ECHO structure
Text1.Text = "Server Trip Time " & ECHO.RoundTripTime & " ms"

later
