This code pings a IP adress so you can make your own pinger very sweeeeet !!!! Please Vote !!!
VBcoders'1) Place a command button on the form and place this code in the Click event
Dim ECHO As ICMP_ECHO_REPLY
Dim pos As Integer
'ping an ip address, passing the
'address and the ECHO structure
Call Ping("209.48.177.35", ECHO)
'display the results from the ECHO structure
Form1.Print GetStatusCode(ECHO.status)
Form1.Print ECHO.Address
Form1.Print ECHO.RoundTripTime & " ms"
Form1.Print ECHO.DataSize & " bytes"
If Left$(ECHO.Data, 1) <> Chr$(0) Then
pos = InStr(ECHO.Data, Chr$(0))
Form1.Print Left$(ECHO.Data, pos - 1)
End If
Form1.Print ECHO.DataPointer
'2) Add a .BAS module and paste this code in that module
'3) Click the command button
