Winsock - Pinging problem

[iceno9]

All,

Urgent this one...

I have a Winsock which sends a string saying "PING" to my controller on the other end.

The controller will respond with a "PING" back, otherwise it will send other monitor data back.

Whats happening is that my VB program seems to be getting confused between the two.....how do i stop this? I have a statement in the dataarrival function saying...

If (data == "PING") then
do this
else
do this


COuld it be that my controller is sending data back too fast??? Or is there another clever way round the problem?

Is it just an ICMP Ping you wish to send. If so you can use VB to send ping and return the result without using the winsock connection. Simply send an ICMP echo and wait for the result.

So will this code run in the background?

The reason i am pinging is to maintain communication - when the PINGing occures, the controller (running a C program) is already connected to my VB end and transfering data quite rapidly. The idea of the pinging it flag an error if the link goes down....for example, if the ethernet cable gets cut.

Im not sure if this code fits the bill?!? Or is there another way?
