[VB]IP Pinger

[Bendik]

Make a new project and make 2 command buttons make command 1's capton select and ping
and command 2's cption clear last ping
and then in the form code put

Dim theIP As String

Private Sub Command1_Click()
theIP = InputBox("Enter an IP") 'makes a box to enter the IP
Dim ECHO As ICMP_ECHO_REPLY
Dim pos As Integer

Call Ping(theIP, ECHO) 'calls to the IP

form1.Print GetStatusCode(ECHO.status) ' gets part of the return
form1.Print ECHO.Address ' gets the next bit
form1.Print ECHO.RoundTripTime & " ms" ' gets a bit more
form1.Print ECHO.DataSize & " bytes" ' gets the next bit

If Left$(ECHO.Data, 1) <> Chr$(0) Then
pos = InStr(ECHO.Data, Chr$(0))
form1.Print Left$(ECHO.Data, pos - 1) ' desplys the ping on form


End If

End Sub


Private Sub Command2_Click()
Unload Me 'makes the form close to clear
form1.Show 'makes the form show again
End Sub[/code]

Now Make A New Module And Put This Code In It:
