ip addresses and pinging from VB

[locutus]

Hi
I have just written a small app to return the IP address of an input
host name ( from a book admittedly) I would like to also ping this
returned IP address, is there an api to do this or should I shell
to the winnt ping.exe to achive this. If the latter of the two how
do I go about passing the IP address ( as a variable ) to the ping.exe

Code would be helpful


PS how do you guys insert code into your replys in them condensed
grey boxes ( is there a secret method ?)


Thanks

Better yet, use the ICMP.DLL file.

Go to www.vbcode.com and look under Internet. On about the third page is an example of how to ping an address.

[john_murphy]

Shell ("ping.exe 192.5.3.199")

will ping it for you.

[john_murphy]

Just in case you do not know you can direct the output to a text file and read in the result....

dim ip_address as string
ip_address = "192.10.11.23"
shell("ping.exe " & ip_address & " > c:\output.txt")

Would you send me your IP Source Code?

The following code was taken directly from vbcode.com (no modifications):

[code]
'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
